Chrome and Safari XSLT using JavaScript

If your XSLT is using xsl:include you might receive weird unexplainable errors but always with the same end result: your transformation failing.

See this chromium bug report and please support it!
http://code.google.com/p/chromium/issues/detail?id=8441

The bug is actually in webkit though. For more info here’s another link which goes into more detail why it doesn’t work.

The only way around this is to pre-process the stylesheet so that it injects the included stylesheets. Which is what a crossbrowser XSLT library like Sarissa will do for you automatically.

If your looking for jQuery solution:
http://plugins.jquery.com/project/Transform/ is a cross browser XSL plug-in. I’ve succesfully used this to get xsl:include working in the past without much hassle. You don’t have to rewrite your xsl’s this plugin will pre-process them for you. Definitely worth looking at as it’s more lightweight then Sarissa.

This test html page works both in Chrome/FireFox/IE.

input.xml is just a simple xml file containing <root />
transform.xsl is the stripped down xsl you posted.

EDIT

It does however seem the $.transform has problems importing stylesheets from included files:

Here’s how to fix this:

Locate

var safariimportincludefix = function(xObj,rootConfig) {

in jquery.transform.js and replace the entire function with this:

var safariimportincludefix = function(xObj,rootConfig) {
    var vals = $.merge($.makeArray(xObj.getElementsByTagName("import")),$.makeArray(xObj.getElementsByTagName("include")));

    for(var x=0;x<vals.length;x++) {
        var node = vals[x];
        $.ajax({
            passData : { node : node, xObj : xObj, rootConfig : rootConfig},
            dataType : "xml",
            async : false,
            url : replaceref(node.getAttribute("href"),rootConfig),
            success : function(xhr) {
                try {
                    var _ = this.passData;
                    xhr = safariimportincludefix(xhr,_.rootConfig);

                    var imports = $.merge(childNodes(xhr.getElementsByTagName("stylesheet")[0],"param"),childNodes(xhr.getElementsByTagName("stylesheet")[0],"template"));
                    var excistingNodes = [];
                    try 
                    {
                        var sheet = _.xObj;
                        var params = childNodes(sheet,"param");
                        var stylesheets = childNodes(sheet,"template");
                        existingNodes = $.merge(params,stylesheets);
                    }
                    catch(exception) 
                    {
                        var x = exception;
                    }
                    var existingNames = [];
                    var existingMatches = [];
                    for(var a=0;a<existingNodes.length;a++) {
                        if(existingNodes[a].getAttribute("name")) {
                            existingNames[existingNodes[a].getAttribute("name")] = true;
                        } else {
                            existingMatches[existingNodes[a].getAttribute("match")] = true;
                        }
                    }

                    var pn = _.node.parentNode;
                    for(var y=0;y<imports.length;y++) {
                        if(!existingNames[imports[y].getAttribute("name")] && !existingMatches[imports[y].getAttribute("match")]) {
                            var clonednode = _.xObj.ownerDocument.importNode(imports[y],true);
                            //pn.insertBefore(clonednode,_.xObj);
                            pn.insertBefore(clonednode,childNodes(_.xObj,"template")[0]);
                        }
                    }
                    pn.removeChild(_.node);
                } catch(ex) { 

                }
            }
        });
    }

    return xObj;
};

Now using the previously pasted test index.html use this for transform.xsl:

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0"
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    >
        <xsl:include href="https://stackoverflow.com/questions/2042178/include.xsl" />
    <xsl:output method="html"/>
    <xsl:template match="https://stackoverflow.com/">
            <xsl:call-template name="giveMeAnIncludedHeader" />
    </xsl:template>
</xsl:stylesheet>

And this for include.xsl

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
    <xsl:template name="giveMeAnIncludedHeader">
        <h1>Test</h1>
    </xsl:template>
</xsl:stylesheet>

With the previously posted fix in jquery.transform.js this will now insert the included <h1>Test</h1> on all the browsers.
