xml

There are two issues. First, whether or not the zip element exists for an employee. Secondly, whether or not there is a value for the element.

For a start, the XML must have a root element. I have called it employees.

<cfxml variable="xmlDoc">
<employees>
    <employee>
         <id>101</id>
         <name>Janice Henry</name>
         <zip>33021</zip>
    </employee>
    <employee>
         <id>102</id>
         <name>Julian Andrews</name>
    </employee>
</employees>
</cfxml>

Each employee element is a child of the xmlRoot, employees. The employee elements are therefore xmlDoc.xmlRoot.xmlChildren[1] and xmlDoc.xmlRoot.xmlChildren[2]. The following loop runs through the employee elements, and displays each employee's zip, if it exists

<cfloop from="1" to="#arrayLen(xmlDoc.xmlRoot.xmlChildren)#" index="idx">
    <cfif structkeyexists(xmlDoc.xmlRoot.xmlChildren[idx], "zip")>
        Element index: <cfoutput>#idx#</cfoutput><br>
        zip: <cfoutput>#xmlDoc.xmlRoot.xmlChildren[idx]["zip"].xmlText#</cfoutput><br>
    </cfif>
</cfloop>
