My code for parsexml:
var parseXml = function (xml) {
var dom = null;
if (window.DOMParser) {
try {
dom = (new DOMParser()).parseFromString(xml, "text/xml");
}
catch (e) { dom = null; }
}
else if (window.ActiveXObject) {
try {
dom = new ActiveXObject('Microsoft.XMLDOM');
dom.async = false;
if (!dom.loadXML(xml)) // parse error ..
window.alert(dom.parseError.reason + dom.parseError.srcText);
}
catch (e) { dom = null; }
}
else
alert("cannot parse xml string!");
return dom;
}
now suppose
s="<a>random</a>";
b=parseXml(s);
now I want to get s back from b. How do I do that?
You need an XMLSerializer in most browsers and the xml property of XML nodes in older version of IE:
function serializeXmlNode(xmlNode) {
if (typeof window.XMLSerializer != "undefined") {
return new window.XMLSerializer().serializeToString(xmlNode);
} else if (typeof xmlNode.xml != "undefined") {
return xmlNode.xml;
}
return "";
}
var xmlStr = serializeXmlNode(b);
You need a XMLSerializer (MDN docu) object for converting your XML tree back to a string:
var ser = new XMLSerializer();
s = ser.serializeToString( b );

For some reason parsing this XML string...I'm getting this error at dom.async = false;
...in theory this should be possible?
$(document).ready( function(){
function parseXml(xml) {
var dom = null;
if (window.DOMParser) {
try {
dom = (new DOMParser()).parseFromString(xml, "text/xml");
}
catch (e) { dom = null; }
}
else if (window.ActiveXObject) {
try {
dom = new ActiveXObject('Microsoft.XMLDOM');
dom.async = false;
if (!dom.loadXML(xml)) // parse error ..
window.alert(dom.parseError.reason + dom.parseError.srcText);
}
catch (e) { dom = null; }
}
else
alert("oops");
return dom;
}
});
According to Here IE11 Cannot be detected by window.ActiveXObject.

Following is the piece of code I am using to retrieve the <b:BusinessUnitId> tag values. The input to the functions are resultXml which is the XML above and attributeName which I am passing as "b:PrivilegeId".
function extractValuesFromXml(resultXml, attributeName)
{
var valueArray = new Array();
var parseXml;
if (typeof window.DOMParser != "undefined")
{
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
}
else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM"))
{
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
}
else
{
throw new Error("No XML parser found");
}
var xmlDoc = parseXml(resultXml);
x = xmlDoc.getElementsByTagName(attributeName);
for (i = 0; i < x.length; i++)
{
if (x[i].childNodes[0] != null && x[i].childNodes[0] != 'undefined' && x[i].childNodes[0].data != null && x[i].childNodes[0].data != 'undefined')
{
valueArray[i] = x[i].childNodes[0].data.toUpperCase();;
}
}
return valueArray;
}
The code works perfectly in IE and Firefox, but I can't seem to get it to work in Chrome, Opera or Safari. I have tried all sorts of things to have this working in these 3 browsers but have failed.
Any help would be appreciated! Thanks.
Well, finally got it to work. IE and Firefox could use the getElementsByTagName("b:PrivilegeId") but Chrome, Opera and Safari could use getElementsByTagName("Privilege").
So, I used this wonderful library here : http://jsfiddle.net/pupunzi/dnJNS/ to detect the browser and modify the code. And now it works like a charm!
My code now looks like the following:
function extractValuesFromXml(resultXml)
{
var valueArray = new Array();
var parseXml;
if (typeof window.DOMParser != "undefined")
{
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
}
else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM"))
{
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
}
else
{
throw new Error("No XML parser found");
}
var xmlDoc = parseXml(resultXml);
if($.browser.msie == true || $.browser.mozilla == true)
{
x = xmlDoc.getElementsByTagName("b:PrivilegeId");
}
else
{
x = xmlDoc.getElementsByTagName("PrivilegeId");
}
for (i = 0; i < x.length; i++)
{
if (x[i].childNodes[0] != null && x[i].childNodes[0] != 'undefined' && x[i].childNodes[0].data != null && x[i].childNodes[0].data != 'undefined')
{
valueArray[i] = x[i].childNodes[0].data.toUpperCase();;
}
}
return valueArray;
}
Attempting to add parameters to an xsl template, for use in a navigation menu.
Trying to figure out how to use the output that IXSLProcessor leaves me with.
I have the following code that works perfectly for Firefox
var xslStylesheet;
var xsltProcessor = new XSLTProcessor();
var myDOM;
var xmlDoc;
var myXMLHTTPRequest = new XMLHttpRequest();
myXMLHTTPRequest.open("GET", "client.xsl", false);
myXMLHTTPRequest.send(null);
xslStylesheet = myXMLHTTPRequest.responseXML;
xsltProcessor.importStylesheet(xslStylesheet);
// load the xml file
myXMLHTTPRequest = new XMLHttpRequest();
myXMLHTTPRequest.open("GET", "client.xml", false);
myXMLHTTPRequest.send(null);
xmlDoc = myXMLHTTPRequest.responseXML;
// set the parameter using the parameter passed to the outputgroup function
xsltProcessor.setParameter(null, "cid", client);
xsltProcessor.setParameter(null, "browser", "other");
var fragment = xsltProcessor.transformToFragment(xmlDoc,document);
document.getElementById("scriptHook").innerHTML = "";
document.getElementById("maincontent").replaceChild(fragment, document.getElementById("scriptHook"));
scroll(0,0);
This is the code I have (mostly pilfered from msdn)
var xslt = new ActiveXObject("Msxml2.XSLTemplate.3.0");
var xsldoc = new ActiveXObject("Msxml2.FreeThreadedDOMDocument.3.0");
var xslproc;
xsldoc.async = false;
xsldoc.load("client.xsl");
if (xsldoc.parseError.errorCode != 0) {
var myErr = xsldoc.parseError;
WScript.Echo("You have error " + myErr.reason);
} else {
xslt.stylesheet = xsldoc;
var xmldoc = new ActiveXObject("Msxml2.DOMDocument.3.0");
xmldoc.async = false;
xmldoc.load("client.xml");
if (xmldoc.parseError.errorCode != 0) {
var myErr = xmldoc.parseError;
WScript.Echo("You have error " + myErr.reason);
} else {
xslproc = xslt.createProcessor();
xslproc.input = xmldoc;
xslproc.addParameter("cid", client);
xslproc.addParameter("browser", "ie");
xslproc.transform();
//somehow convert xslproc.output to object that can be used in replaceChild
document.getElementById("scriptHook").innerHTML = "";
document.getElementById("maincontent").replaceChild(xslproc.output, document.getElementById("scriptHook"));
}
}
Any and all help is appreciated, cheers.
With Mozilla you can exchange nodes between XSLT and DOM but with IE you need to take the XSLT transformation result as a string and feed that to IE's HTML parser; so for your sample I think you want
document.getElementById("scriptHook").outerHTML = xslproc.output;
which will replace the scriptHook element with the result of the transformation.
I have been working on adding XML element to XML structure without success, here is my code.
var parseXml;
if (window.DOMParser) {
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
}
else if (typeof window.ActiveXObject != "undefined" && new window.ActiveXObject("Microsoft.XMLDOM")) {
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
}
else {
parseXml = function() { return null; }
}
var xmlTree = parseXml("<root></root>");
function add_children(child_name,parent_name)
{
str = '<'+child_name+'></'+child_name+'>';
//strXML = parseXml(str);
$(xmlTree).find(parent_name).append(str);
var xmlString = (new XMLSerializer()).serializeToString(xmlTree);
console.log(xmlString);
}
add_children("apple","root");
add_children("orange","root");
add_children("lychee","root");
but console is showing <root/> all three times
The problem is that you are creating the node in the Html document, not in the XML one, so you can't append it. Change this line:
str = '<'+child_name+'></'+child_name+'>';
For this one:
str = xmlTree.createElement(child_name);
See the working code in http://jsfiddle.net/W9Wpb/

Mine seems to work fine with less code. Try replacing your onDataAvailable function code with:
var binaryInputStream = Components.classes["#mozilla.org/binaryinputstream;1"].createInstance(Components.interfaces.nsIBinaryInputStream);
binaryInputStream.setInputStream(inputStream);
this.receivedData.push(binaryInputStream.readBytes(count));
