Hi Tom (Schreck)
Your code - for retrieving specific elements and their children - looks
good. The only alternative I can suggest is to use one of the existing
custom tags (like soXML or the XML Toolkit) although these won't give you
any performance advantages. I've copied below the way the code for doing
this with the Toolkit tags:
<!--- create an XML datasource from your information --->
<cf_xmldatasource name = "ds_ElementTemplates">
<ElementTemplates>
<TextBox>
<elementType>TextBox</elementType>
<elementName>This is the element Name</elementName>
<elementLabel/>
<elementLabelClass/>
<elementClass/>
<elementPosition/>
<elementSize/>
<elementMaxLength/>
<DefaultValue/>
<xslMember/>
<editLevel/>
<ynIsRequired/>
</TextBox>
<Memo>
<elementType>Memo</elementType>
<elementName/>
<elementLabel/>
<elementLabelClass/>
<elementClass/>
<elementPosition/>
<elementCols/>
<elementRows/>
<DefaultValue/>
<xslMember/>
<editLevel/>
<ynIsRequired/>
</Memo>
</ElementTemplates>
</cf_xmldatasource>
<!--- Query the datasource using XPath --->
<cf_xmlquery name = "testQuery" datasource = "ds_ElementTemplates">
//ElementTemplates/TextBox
</cf_xmlquery>
<!--- output the Query --->
<cfoutput query = "testQuery">
elementType is #TextBox_elementType#<br />
elementName is #TextBox_elementName#<br />
elementLabel is #TextBox_elementLabel#<br />
</cfoutput>
