| BachusII on Jan 19, 2006 at 8:41:47 AM (# 8) Crazily enough most examples of document.evaluate employ their own selfmade functions to resolve. I found createNSResolver while writing my own resolver. (Which reminds me that I need to update that page with my findings.)

thanks for your answer....
However it still give me this problem
": uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIDOMXPathEvaluator.createNSResolver]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: file:///d:/profiles/ben010/Desktop/Event%20Lo_files/eventloggertable.htm :: loadXML :: line 79" data: no]"
my code is:
var xsl = document.implementation.createDocument("","",null);
xsl.load("eventlogger.xsl");
var currSort1DirNodeVal = xsl.evaluate("//xsl:param[@name=\"sort1By\"]/@select", xsl.createNSResolver( xsl.documentElement ) , null, 9,null).singleNodeValue
Thanks....

This message has been edited.To make the script work cross-browser, here's an includable bit to add the MS parser's selectNodes to the Mozilla DOM object. I like this method better, because it allows a simple way to check the existence of matching nodes, e.g.
var myNodes=xsl.documentElement.selectNodes("//xsl:param[@name=\"sort1Dir\"]");
if(myNodes.length>0){
currSort1DirNodeVal = myNodes[0].getAttribute["select"];
}else{
// Data missing
}
Include this script to use selectNodes in IE, NS & FF:
/*
Prefix-correcting evaluate statement from http://www.faqts.com/knowledge_base/view.phtml/aid/34022/fid/119
*/
if( document.implementation.hasFeature("XPath", "3.0") ){
XMLDocument.prototype.selectNodes = function(cXPathString, xNode){
if( !xNode ) {
xNode = this;
}
var defaultNS = this.defaultNS;
var aItems = this.evaluate(cXPathString, xNode,{
normalResolver:
this.createNSResolver(this.documentElement),
lookupNamespaceURI : function (prefix) {
switch (prefix) {
case "dflt":
return defaultNS;
default:
return this.normalResolver.lookupNamespaceURI(prefix);
}
}
},XPathResult.ORDERED_NODE_SNAPSHOT_TYPE,null);
var aResult = [];
for( var i = 0; i < aItems.snapshotLength; i++){
aResult[i] = aItems.snapshotItem(i);
}
return aResult;
}
Element.prototype.selectNodes = function(cXPathString){
if(this.ownerDocument.selectNodes){
return this.ownerDocument.selectNodes(cXPathString, this);
}else{
throw "For XML Elements Only";
}
}
/* set the SelectionNamespaces property the same for NN or IE: */
XMLDocument.prototype.setProperty = function(p,v){
if(p=="SelectionNamespaces" && v.indexOf("xmlns:dflt")==0){
this.defaultNS = v.replace(/^.*=\'(.+)\'/,"$1");
}
}
XMLDocument.prototype.defaultNS;
}
mikejr83 on May 9, 2006 at 9:25:52 AM (# 13)After reading many articles on this subject I have yet to find a "good" solution in such that it does not crash in FF. I have seen the above code in many different websites. I've used this one and several others. On my current implementation the code breaks on the similar spot in the above code:
this.createNSResolver(this.documentElement),
The error I get:
Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsIDOMXPathEvaluator.createNSResolver]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: http://localhost:3421/MVP%20Testing%20Items/mozxpath.js :: anonymous :: line 10" data: no]
Line 10 being:
var oNSResolver = this.createNSResolver(this.documentElement)
I do not know why this keeps happening. I've been looking into why this error is being generated. If someone could elaborate it would be much appreciated.
