How to create and return a nodeset in a javascript

jerry.gadd · October 16th, 2003, 04:47 AM

I need a function to create and return a nodeset to a variable from within my XSLT.

here is a small example of what I intend to do

Code:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:msxsl="urn:schemas-microsoft-com:xslt" xmlns:ja="http://mycode/js" extension-element-prefixes="js msxsl">
    <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
    <msxsl:script language="JavaScript" implements-prefix="js">    
        <![CDATA[            
            function getnewnodes() { 
                var xmlDoc = new ActiveXObject("MSXML2.DOMDocument");
                var str;
                ...
                xmlDoc.loadXML("<root>" + str + </root>");
                return xmlDoc;
            };
        ]]>
    </msxsl:script>

    <xsl:template match="/">
        ....
        <xsl:variable name ="results" select="js:getnewnodes()"/>
        ....
    </xsl:template>
</xsl:stylesheet>

I'm not sure why you are doing this, why not just use node-set function?

The sample does not describe what I am actually doing,
this is to complicated.

However, I can say this.
Every time I find a specific structure in my source file I need to run an extremely complicated algorythm on the array of values it holds.
The result of the algorythm is another array of values, which I need to slot into my output at different places.

As the source array is held in a nodeset i send the function the node-set and let the function get the separate values from it.

The problem is how do I return the array of results back to xsl?
I thought that sending it back as a node-set was the best idea.
But I can not get it to work

You're right, it is complicated. I don't really understand but if you return it as a valid xml string then you could use the msxml:node-set function on that.

Now I dont understand!

I think your saying that the function should return a string of the xmlDoc, something like
"<resultarray><index0>1</index0><index1>2</index1><index2>3</index2></resultarray>"

But then how do I use msxml:node-set on this?

Something like:

Code:

<xsl:variable name="myDoc" select="msxml:node-set(js:getnewnodes())"/>

I only get the string and not the node-set returned

I am using msxsl:node-set(), is this the same or not?

Sorry, my typo. So now your getnewnodes looks like:

Code:

function getnewnodes()
{ 
                var str;
                ...
                return "<root>" + str + </root>";
};

Hope I've understood :)

I have now replaced the javascript function with the equivalent using xsl:variables, its a bit long but at least it works.
I still need some javascript functions for the some maths, but thats ok.
It keeps the javacode small.
