I'm writing a packaged Chrome Web App and trying to parse external XML. It works when I download the XML file to my server, but does not work when I change the XML file to the location on the web.
For example, I am trying to access this file: .xml
Here is my JavaScript code (note that HTML ):
function dashboardContent() {
html="";
xmlhttp=new XMLHttpRequest();
xmlhttp.open("GET",".xml",false);
xmlhttp.send();
xmlDoc=xmlhttp.responseXML;
html+=xmlDoc.getElementsByTagName("to")[0].childNodes[0].nodeValue;
html+=xmlDoc.getElementsByTagName("from")[0].childNodes[0].nodeValue;
html+=xmlDoc.getElementsByTagName("body")[0].childNodes[0].nodeValue;
document.getElementById("contentArea").innerHTML=html;
}
In my Chrome Web App manifest.json file, I put the following under permissions per Google's manifest requirement for Cross-origin XMLHttpRequests:
{
"name": "BirdTrax",
"version": "0.1.1",
"description": "Birding explorer to help you plan birding trips and find recently eBirded sightings, rarities, and checklists in your area",
"icons": {
"16": "icons/helloWorld_16.png",
"128": "icons/helloWorld_128.png"
},
"app": {
"launch": {
"local_path": "main.html",
"container": "tab"
}
},
"background_page": "background.html",
"options_page": "options.html",
"permissions": [
"/*",
"notifications",
"unlimitedStorage"
],
"incognito": "split"
}
I'm not sure if I'm still missing something, but the code isn't working for me. Any suggestions, tips, ideas? I really appreciate any help!!

- @RobW The function is called when the <body> element loads. <body onload="dashboardContent()". The script linked in the <head> of my main.html document which loads as default first page. – zdebruine Commented Jul 7, 2012 at 14:50
- I think I'll just copy Google's own example code and try to work from there. Thanks for your help! – zdebruine Commented Jul 7, 2012 at 15:00

Reset to default 3Suffice a wildcard after /. Otherwise, you're allowing your extension to only request pages at the root.
"permissions": [
"http://www.w3schools./*",
In your case, you're requesting only one URL. It might be even better to restrict the pattern even more:
"permissions": [
"http://www.w3schools./xml/note.xml",
