   RE: [xml-dev] Calling functions from XSLTs

[ Lists Home | Date Index | Thread Index ]

Thanks for the help folks.

I have another question. I am trying to transform instance of one schema
to an instance of another schema using XSLTs, but the problem is that
sometimes instead of an instance I have an XPath. How do I handle that? 

Example: I have to convert the following instance:  <abc>	
<name> Seattle </name>
<state> WA </state>
into another instance  <xyz>	
				 <result> Seattle is in WA </result>

That's fairly simple to do, but in some cases I might get an XPath
/abc/[name=Seattle] and I need to convert this into the same schema,
(but with a different rule), so that the result will be
  <result> Seattle is a city</result>    // "is a city" is a constant
Is there any way to handle this?? One simple way I thought about was to
convert the XPath into a partial instance and then write the XSLT, but
this method runs into trouble the moment one has operators (AND, OR) in
the XPath. 

Thanks again

In order to invoke self defined functions from within XSL stylesheet, 

1.You can add extension objects to XsltArgumentList and invoke any
methods on those from within your style sheet.


2.Use msxsl:script. There is no restriction on the namespaces you can
use inside msxsl:script.

However only certain namespaces are supported by default (i.e there is
no need to fully qualify the namespaces when using classes from these
namespaces). These are:- 


Classes can still be used outside of the namespace, except that the name
must be namespace qualified. e.g. System.Diagnostics.Process
