copied!<p>In principle you need to use the XPathNodeIterator to return node sets (as Samjudson says). I take it that the example you gave is a degenerated function, as you do not supply it with any parameters. However, I think it is instructive the see how you <em>could</em> fabricate nodes out of thin air. </p> <pre><code><msxsl:script language="C#"> XPathNodeIterator getNodes() { XmlDocument doc = new XmlDocument(); doc.PreserveWhitespace = true; doc.LoadXml("<root><fld>val</fld><fld>val2</fld></root>"); return doc.CreateNavigator().Select("/root/fld"); } </msxsl:script> </code></pre> <p>However, typically you would want to do something in your function that is not possible in xslt, like filtering a node set based on some criteria. A criteria that is better implemented through code or depends om some external data structure. Another option is just that you would to simplify a wordy expression (as in the example bellow). Then you would pass some parameters to you getNodes function. For simplicity I use a XPath based filtering but it could be anything:</p> <pre><code> <msxsl:script language="C#"> XPathNodeIterator getNodes(XPathNodeIterator NodesToFilter, string Criteria) { XPathNodeIterator x = NodesToFilter.Current.Select("SOMEVERYCOMPLEXPATH["+Criteria+"]"); return x; } </msxsl:script> <xsl:for-each select="user:getNodes(values/val,'SomeCriteria')"> ... </xsl:for-each> </code></pre> <p>Hopes this helps, Boaz</p>
