Synopsis

                  
                  
                  XmlSearch(XmlDocObj, XPath_exp)

Searches the specified ColdFusion XML document object using an XPath expression. If a successful match is made, the function returns an array of XML document object nodes that match the search criteria. The following example reads in an XML news feed from macromedia.com, parses it into an XML document object, uses XPath to return only the XML nodes containing tutorials, and outputs the results to the browser:

<cfhttp URL="http://www.macromedia.com/devnet/resources/macromedia_resources.xml"
        method="Get">
   
<cfset DesDev = XmlParse(cfhttp.FileContent)>
<cfset SearchResults = XmlSearch(DesDev, "/macromedia_resources/resource[attribute::
type='Tutorial']")>
   
<h2>Available Tutorials</h2>
<cfloop index="i" from="1" to="#ArrayLen(SearchResults)#">
  <cfoutput>
  <a href="#SearchResults[i].URL.XmlText#">#SearchResults[i].Title.XmlText#</a><br>
  </cfoutput>
</cfloop>
