JavaScript - Reading Data From Xml File
i am thinking of using a xml file as a data base
for example , the xml file stores a list of reference numbers which is allocated to a url or a name such as 0123456789 and i have a text box on a webpage and the user types in a reference number and the javascripts reads the xml file to check if its a valid reference number i.e a registered number i am new to working with xml etc... so would be nice to have a little help here EXAMPLE <DATA> <REF> <0123456789>JOE</01234567890> <1111111111>www.google.com</1111111111> </REF> </DATA> id like it to read the specific data thats contained within the tag such as 0123456789's tag = JOE Similar TutorialsHi all, How can i read CSV data from the text file using Java Script.Please give me the script for the problem. Thanx, Nari need help.... I need to create a web page that can pull data from sensatronics senturion sensor probe. The unit has a web server that displays temperature, humidity,etc. You can also query it for from telnet or webpage which kicks back xml. My page needs to read the values of the probes. I don't know much about javascript and have been unsuccessful trying to use httprequest. I guess this would be considered cross domain as well? Here is the XML that is generated from the unit. I get this by pulling through a web browser x.x.x.x/xmldata Thanks <?xml version="1.0" encoding="ISO-8859-1"?> <Sensatronics id="S10604" hb="10554"> <Group id="1"> <Probe id="100"><Value>75.2</Value></Probe> </Group> <Group id="2"> </Group> <Group id="3"> </Group> <Group id="4"> </Group> <Group id="5"> </Group> <Group id="6"> </Group> <Group id="7"> </Group> <Group id="8"> </Group> <Group id="9"> <Probe id="99"><Value>1.0</Value></Probe> <Probe id="1"><Value>79.5</Value></Probe> <Probe id="2"><Value>34.3</Value></Probe> <Probe id="3"><Value>35.6</Value></Probe> <Probe id="4"><Value>0.0</Value></Probe> </Group> </Sensatronics> hi Guys , I have some instructions in property files , now I wat to retrive that fmt tag values in scriptlets So that I can modify the content in property file So i have written the code in jsp as <c:set var="mailBodyData" value='<fmt:message key="confirmemail.body.message"/>' scope="request"/> <% out.println("hero "+request.getAttribute("mailBodyData")); %> but its displays empty , Also I have tried as <% String str ="<fmt:message key="confirmemail.body.message"/>' %> but its throughs the Compilation error , Pls help , So that I can retrive the data from fmt to Scriptlets Dear frnd I wanna read on html page , and i have script : " [I]<html> <head> <script type="text/javascript" language="javascript"> function Read() { var Scr = new ActiveXObject("Scripting.FileSystemObject"); var CTF = Scr .OpenTextFile("C:\\123.txt", 1, true); data = CTF .ReadAll(); document.write("<pre>" + data + "</pre>"); CTF .Close(); } </script> </head> <body onLoad="Read()" > </body> </html> [I] " But as its using activex control not allowing in all browser . Have you any other way with pure js to read the file contains ? or allowing activex in all browser ? Hi I'm reading a text file, manipulating the string that I've read, and then writing to a new text file called temp. The error that I am getting is basically reading past the end of the file. function SpaceFileEntries() { fso = new ActiveXObject("Scripting.FileSystemObject"); filename = "NDELPROF.txt"; path1 = document.getElementById("lblDataOutputDirectory").innerText + "\\" + filename; path2 = document.getElementById("lblDataOutputDirectory").innerText + "\\temp.txt"; s = fso.OpenTextFile(path1); j = fso.CreateTextFile(path2 , true); do { text = s.readLine(); partOne = text.substring(0,34); lastPart = text.substring(35, 54); space = " "; j.write(partOne); j.write(space); j.writeline(lastPart); } while ( text != null ) s.Close(); j.Close(); } Can someone please help me find this bug in the code. I know it's got to do with the while statement, but can't think or find good alternatives. Thanks. Daniel Somebody had posted this query on how to read text files using JavaScript.......can't find that post now... Anyways, though it's not possible to read text-files using JavaScript it is possible to read XML files using it. Here is an XML based JavaScript Ticker http://www.dynamicdrive.com/dynamicindex2/xmlticker.htm It works only on browsers supporting XML (IE) Enjoy! Hey guys, I'm writing a script and I've encountered a problem.. I have a txt file with many words, each word in a different line. For example: the file words.txt contains: word1 word2 word3 word4 word5 I need to load the content of the file into a variable in my script. I prefer that all the words will be in the same variable with line breaks, but if you'll figure out a way to put it in an array, it's ok too. I really don't know how to do it, and I tried to google but didn't understand.. By the way, I don't want to change the txt file to js file, I need it to remain txt.. Can anybody help me with that? Thanks Alot, Ran Hi I have a large'ish project under development. The code below distills the problem I am having. In essence, I am trying to read in an XML file. It appears to load okay but when I try to count how many there are of a certain tag (The "Team" tag) I am told that there are zero. This is despite being told that that file loads okay (as the callback function is called). Javascript and the xml file is below. I hope that it is easy to follow. When the page is loaded, the initialize function is called. I first check my browser as I only need this to work on a Mozilla browser (I am using Mozilla Firefox 3.6.3). I then load the xml file and the callback function (fileLoaded) is called. I then try to find out how many "Team" tags I have, but get the message that there are zero. Sorry if this is a simple question but I have spent the best part of yesterday trying to get this to work. Any help would be appreciated. Thx G === javascript === Code:

Hi I have written the following code to read contents of a text file using FileReader object of HTML 5 for Google Chrome. Quote: <script> function handle_files(files) { var i; if (checkBrowser("Chrome")) { for (i = 0; i < files.length; i++) { file = files[i]; var reader = new FileReader(); ret = []; reader.onload = function (e) { console.log(e.target.result) } reader.onerror = function (stuff) { console.log("error", stuff) console.log(stuff.getMessage()) } text = reader.readAsText(file[i]); alert(text); } } } </script> ---------------------- <input type="file" multiple="multiple" onchange="handle_files(this.files)"> Unfortunately, the variable text always displays as undefined. Everything above the line text = reader.readAsText(file[0]); works fine. How can I fix it?. Or is there any other solution to read a text file using HTML5/JavaScript on Chrome? Thanks in advance. i am using the jquery plugin uploadify as an image uploader, i want the image to be able to be uploaded and then redirected to another page where you will see a thumbnail of the picture and be able edit the caption, description, etc... ... i am not interested on how to do it but only how to control variables from the files uploaded.... i have uploadify on a upload.php and it accesses the script uploadify.php to process the file handling in a regular php uploader, i could put the uploaded file information into variables and redirect to another page and use those variables... with uploadify i am not sure how to accomplish this... i can't use uploadify.php to create variables to be used, after the upload, the user remains on the page uploadify is installed on(upload.php)... how can i take the file information and put it into variables and be redirected with the ability to call those variables i'm sorry i am new to javascript and i'm trying to understand it the best i can, if someone could help me achieve this Hello, I'm trying to parse my data from an xml file now and print it out on the page based on date from my existing code. I have that working, with each item formatted the same way on the page What I'd like to do now is alter it a bit to make the most recent (the item listed on the top of the page) formatted differently and the rest of them as it is now. Something like - (if 1st <li> then build html like this else build html like that) I hope this makes sense. Code: <?xml version="1.0" encoding="utf-8" ?>

Hi, I'm trying to write a little Javascript that would parse a CSV file that contains a name and date, and only display the name if the date matches today. Here's some example data: Name, Date Joe, 6/10/2010 Jane, 7/11/2010 If today were 6/10/2010, the output of the script would just be "Joe" Can anybody help? Thanks! well i'm kind of new to this website and scripting with javascript but i am wondering: in a client side .js file i have some coding which results in a string which is stored in a variable called exportData now i want that string to be written into a text file on a server but how do i do that? it is not local on the client's pc and i can't find how to do it anywhere... can you guys help me? greetings, Fady Hello All, I always wonder that how to display any sort of data or HTML codes by just simply calling or including a Javascript file in other HTML file or a webpage. If you didn't understand what I want to say, I would like to give an example like AdSense gives a javascript code that need to be put where we want to show ads. And the ads appear, similarly how to display any HTML code with just inclusion of Javascript file. An other example is - <script type="text/javascript" src="http://example.com/scripts/javascript/source/somescript.js"> <div id="div_one"></div> <div id="div_two"></div> <div id="div_three"></div> </script> Now this script will show some HTML inside first div, some on second and so on. So How can I do that, please explain with an example... Thanks. I am trying for a javascript code that would ask for the excel file location when run, fetch data from two columns till eof in an excel file (MS Excel 2010), append it to an existing text file and upload the plain text file to an ftp location. The ftp username, password and location needs to be hard coded in the script. Is this possible? All, Say I have the following code: Code: <!DOCTYPE html>
<html>
<head>
<style>img{ height: 100px; float: left; }</style>
<script src="http://code.jquery.com/jquery-1.7rc2.js"></script>
</head>
<body>
<div id="images">
</div>
<script>
$.getJSON("http://api.flickr.com/services/feeds/photos_public.gne?jsoncallback=?",
{
tags: "cat",
tagmode: "any",
format: "json"
},
function(data) {
$.each(data.items, function(i,item){
$("<img/>").attr("src", item.media.m).appendTo("#images");
if ( i == 3 ) return false;
});
});</script>
</body>
</html>
This came from the jQuery website. What I would like to do is change the link to something like this: https://graph.facebook.com/me/friend...ss_token=12345 The data that comes back is something like: Code: {
"data": [
{
"review_comment": "Here is a comment",
"id": "12"
},
{
"review_comment": "Testing With more",
"id": "34"
},
{
"review_comment": "Third comment",
"id": "643"
},
{
"review_comment": "More Comments",
"id": "120"
},
{
"review_comment": "Testing",
"id": "3455"
}
]
}
What I would like to do is basically read all of the review_comment tags and basically rotate these to display them on the webpage. So have "Here is a comment" be displayed for like 10 seconds and then fade out and have "Testing with More" fade in and be displayed for another 10 seconds etc. What is the best way to do this? I'm not sure how to change my JSON code above to acheive this. Would I need to basically put the comments in a div and then use jQuery to fade in the divs in and out? Any help you could provide would be greatly appreciated!! I would like to modify an old script retrieve a registry key and sifting through the many forums put this together but not sure if this is correct? Thanks Code: <html>
<head>
<script language="javascript">
<!--
var value;
var Shell;
var cicserver;
Shell = new ActiveXObject("WScript.Shell");
value = Shell.RegRead("HKLM\\Software\\Interactive Intelligence\\EIC\\Notifier");
if value = "servername1"
{ cicserver = "servername1"
}
else
{ cicserver = "servername2"
}
Hi all, I am having trouble trying to use the substring String method. Relevant HTML code: Code: <img id="news" src="../images/news.png" alt="News" onmouseover="change(this)" /> Relevant JavaScript code: Code: function change(element) {
if (element.id == "news" && element.src.substring(3,5) != "../") {
element.src = "../images/news.png";
alert(element.src.substring(3,5));
}
else if (element.id == "news" && element.src.substring(3,5) == "../") {
element.src = "../../images/news.png";
}
}
I want the image to change to another image, but depending on the src in the HTML code. This is so that it can locate the correct folder. However, it doesn't work, and I tried using an alert statement to show me what JavaScript is reading and it seems to read "e:", which is not correct. It never reads "../", which it should. I don't know how to solve this problem, any ideas? Hi there! I'm having a little bit of trouble, I've read through tutorials on parsing XML to Javascript and such, but the XML file I'm working with is very different to the ones the tutorial showed me. Normally it'd be like Code: <here> <there></there> </here> But the one I'm wanting to work in looks like this: Code: <rowset name="names" columns="name"> <row name="this"> <rowset name="fun" columns="name"> <row name="that"> </rowset> </row> </rowset> To make it more clear, my question to you is: How can I parse <row name="that"> where only we only have <row name="this"> Hi, I am a newbie at XML and this issue is proving to be a tough nut to crack for me. My AJAX query returns me an XML response of the following structure for a query on "ind": <countries> <country> <name>India</name> <capital>New Delhi</capital> </country> <country> <name>Indonesia</name> <capital>Jakarta</capital> </country> </countries> How do I transform the XML response into a HTML layout? Particularly, how do I get down to the value at each node?How do I traverse the XML document using JS? Is this (using XML) better than JSON (other than the obvious platform-independence)? Which is better? Thanks! |
