CFHTTP.FileContent

Hello I have the below, when the file is read  firstchild.XMLName returne "errors" but the actual line of the CFHTTP.FileContent returned is

400 xxxx, xxxxxxx xxxxxx.

What I can not figure out is the word errors found in the "<cfelseif firstchild.XMLName is 'errors'>"

<cfhttp url="xxxxx" method="POST" resolveurl="No" throwonerror="Yes">
            <cfhttpparam name="xxxxx" type="Formfield" value="#xxxx#">
            <cfhttpparam name="xxxx" type="Formfield" value="#xxxxx#">

</cfhttp>

        <cfset xmlfile = CFHTTP.FileContent>
        <Cfset MYXML = XmlParse(xmlfile)>
        <cfset XMLResponseBook = MYXML.xmlroot>
        <cfset numchildren = arraylen(XMLResponseBook.XmlChildren)>
        <cfset firstchild = XMLResponseBook.XmlChildren>
        <cfset numgrandkids = arraylen(firstchild.XmlChildren)>

       
        <cfloop from="1" to="#numchildren#" index="i">

            <cfset firstchild = XMLResponseBook.XmlChildren>
            <cfset numgrandkids = arraylen(firstchild.XmlChildren)>
            <cfif firstchild.XMLName is 'confirmation'>
                <cfset confirmation = firstchild.XmlText>
            <cfelseif firstchild.XMLName is 'errors'>
                <cfset errid = grandkid.XmlChildren.XmlText>
            </cfif>
        </cfloop>

        <cfset xmlfile = CFHTTP.FileContent>
        <Cfset MYXML = XmlParse(xmlfile)>
        <cfset XMLResponseBook = MYXML.xmlroot>
        <cfset numchildren = arraylen(XMLResponseBook.XmlChildren)>
