RE: Allowed return data types using addobject?
Hey Neil, In msxml's msxsl:script element, the input and return datatypes must either be: 1. simple (number or string), or... 2. a nodelist (IXMLDOMNodeList**) That's why if you ever pass a "node" or nodeset into an msxsl:script method, you have to call "nextNode()" or "item(index)" on the input parameter before you work with it all... even if you think you're only passing in a single node. The most common way of returning a nodeset back to an xslt context from your msxsl:script method, would be to use "selectNodes" instead of "selectSingleNode".

Hi, I am using ASP and MSXML. I am calling a COM object (written in VB) that is made available to an XSLT style sheet using XSLTprocessor.addobject. I can successfully call a method in the object from the style sheet that returns xml as a string ( so < becomes < etc.) to an xsl:variable but I want to call one that returns a tree to be converted into a node-set. I have tried all sorts of methods to accomplish this but none have been entirely successful. What data type should I use for the return value (within VB) of the COM method to achieve this and what should I be doing to turn this value into a node-set. Is it even allowable to return an object? My current approach is call a method that takes a string and returns an MSXML2.DOMDocument using: <xsl:variable name="msid"><xsl:value-of select="//rsc:docroot/@msid"/></xsl:variable> <xsl:variable name="links" select="myObj:resolveLinks(string($msid))"/> <xsl:variable name="doclinks" select="msxsl:node-set($links)"/> The ASP page that does the work tends to hang and time out. Any advice is much appreciated. Thanks, Neil. XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list
