[Sarissa-users] Internet Explorer Javascript Issue with Sarissa

[Lyndsey P. <lyn...@cu...>]

Hi,

 

I have searched this list to see if anyone had a similar problem, and I am
not an expert with xml, xslt or sarissa so please forgive my ignorance on
certain matters regarding these subjects.

 

I am using a mixture of xml/xslt/sarissa and javascript to transform xml
docs into their respective xslt html output.

 

You can see the basics of the application here (note that the task I am
debugging is converting pounds to US dollars, I don't expect anything else
to work. Also, I only set up the URL this evening so it may not be available
just yet):

If you view this in firefox no problems at all so far.  You should get a
message like so:

Result :2368.951USD
1 GBP = 1.937USD

You have gained $62.495

If you'd bought this at Thomas Cook, you would have received $2255.090! 

 

View it in IE6 and the application seems to lose it's variable values. View
it in IE 7 and I get a javascript error.

 

I downloaded vwd to use it in conjunction with IE 7 as a javascript debugger
(idea from this blog
http://www.berniecode.com/blog/2007/03/08/how-to-debug-javascript-with-visua
l-web-developer-express/)

 

And the javascript errors seem to get triggered around line 245 of the
sarissa.js file - vwd says:

 

"Msxml6.dll:required attribute '{http://www.w3.org/1999/XSL/Transform}
version' is missing."

 

 

Line 245 in the sarissa,js is:

 

"this.template.stylesheet = converted;"

 

And the code block is :

 

XSLTProcessor.prototype.importStylesheet = function(xslDoc){

        if(!_SARISSA_THREADEDDOM_PROGID){

            _SARISSA_THREADEDDOM_PROGID =
Sarissa.pickRecentProgID(["MSXML2.FreeThreadedDOMDocument.6.0",
"MSXML2.FreeThreadedDOMDocument.3.0"]);

        }

        xslDoc.setProperty("SelectionLanguage", "XPath");

        xslDoc.setProperty("SelectionNamespaces",
"xmlns:xsl='http://www.w3.org/1999/XSL/Transform'");

        // convert stylesheet to free threaded

        var converted = new ActiveXObject(_SARISSA_THREADEDDOM_PROGID);

        // make included/imported stylesheets work if exist and xsl was
originally loaded from url

        try{

            converted.resolveExternals = true; 

            converted.setProperty("AllowDocumentFunction", true); 

        }

        catch(e){

            // Ignore. "AllowDocumentFunction" is only supported in MSXML
3.0 SP4 and later.

        } 

        if(xslDoc.url && xslDoc.selectSingleNode("//xsl:*[local-name() =
'import' or local-name() = 'include']") != null){

            converted.async = false;

            converted.load(xslDoc.url);

        } 

        else {

            converted.loadXML(xslDoc.xml);

        }

        converted.setProperty("SelectionNamespaces",
"xmlns:xsl='http://www.w3.org/1999/XSL/Transform'");

        var output = converted.selectSingleNode("//xsl:output");

        //this.outputMethod = output ? output.getAttribute("method") :
"html";

        if(output) {

            this.outputMethod = output.getAttribute("method");

        } 

        else {

            delete this.outputMethod;

        } 

        this.template.stylesheet = converted;

        this.processor = this.template.createProcessor();

        // for getParameter and clearParameters

        this.paramsSet = [];

    };

 

 

Looking at Mike Kay's response here:
http://www.oxygenxml.com/archives/xsl-list/200003/msg00795.html

This appears to be because of a missing 'version' attribute. However in my
'calc.xsl' file where I transform the xml, there is a version attribute so I
am confused. I have checked the validation of the calc.xsl file in an xml
editor called 'Xray' and in Firefox and all seems ok.

 

I am wondering if there is a problem with the version attribute being
omitted here:

 

xslDoc.setProperty("SelectionNamespaces",
"xmlns:xsl='http://www.w3.org/1999/XSL/Transform'");

 

Or if this is symptomatic of something else - some oversight I have made.

 

All help is greatly appreciated as I am going bonkers with this now!

Any ideas?

 

Thanks in advance!
