Help with Webservices and XML

[johne417]

I'm doing a webservices call and having some troubles.

Here's the code in my cfc:
<cfcomponent
displayName=&quot;Detail of an Individual Account&quot;
hint=&quot;Returns the detail of a single individual account&quot; >

<cffunction
name=&quot;IndividualAccountDetail&quot;
output=&quot;false&quot;
access=&quot;remote&quot;
displayname=&quot;Detail of an Individual Account&quot;
hint=&quot;Returns the detail of a single individual account&quot;
returntype=&quot;string&quot;>

<cfxml variable=&quot;IndividualAccounts&quot;>
<IndividualAccounts>
<firstname>John</firstname>
<lastname>Smith</lastname>
<IndividualAccounts>

<cfset unParsedXML=&quot;#IndividualAccounts#&quot;>
<cfreturn unParsedXML>

</cffunction>
</cfcomponent>

----------------------------------------------------------

In my base page I call the CFC from
here's the relevant code:

<cfinvoke webservice=&quot;#application.siteurl#/WebServices/IndividualAccountDetail.cfc?WSDL&quot;>
returnvariable=&quot;userDetail&quot;
method=&quot;IndividualAccountDetail&quot; >
</cfinvoke>

<cfset temp=xmlParse(userDetail)>
<cfdump var=&quot;#temp#&quot;>

------------------------------------
I get the following error:
Document root not found

If I comment out the xmlparse(userdetail) line, the cfdump returns 'coldfusion.xml.XmlNodeList@2daf89'.

I have no idea why I'm getting that error? Is my XML invalid or something?

Thanks in advance for any help.

OOPs, I just noticed that while retyping in the post box I missed the / in my close Individual Accounts tag in the XML. It's there in my real code though, problem still there.

Do you have a close tag for your

CFXML

, though?

<cfxml variable=&quot;IndividualAccounts&quot;>
<IndividualAccounts>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</IndividualAccounts>

</cfxml>

Also, check out the comments at the bottom of the LiveDocs for CFXML:

http://livedocs.macromedia.com/coldfusion/6.1/htmldocs/tags-b21.htm

Since you're writing a CFC, I assume you're using

<cfsetting enablecfoutputonly=&quot;yes&quot; ...>

somewhere. So you'd need to wrap the entire document definition in CFOUTPUTs:

<CFXML variable=&quot;IndividualAccounts&quot;>
<CFOUTPUT>
<IndividualAccounts>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</IndividualAccounts>
</CFOUTPUT>
</CFXML>

in order for anything to be saved to the IndividualAccounts variable.

Thanks for the reply Carl.

I did have my </cfxml> in production as well. Gotta be more careful retyping stuff...

And I don't have a <cfsetting enablecfoutputonly=&quot;yes&quot; ..> in the cfc either.

Strange thing is, when I do a IsXMLDoc on the IndividualAccounts variable in the cfc, I get a &quot;Yes&quot;.
Pass it to the userDetail variable in the calling page, do a IsXMLDoc on it there (without doing anything else to it), and I get 'No'.

Ahhh... sure... that's all you needed to say. ;-)

Your CFFUNCTION is saying it's returning a string (which is what you're expecting for the XMLParse)... but what you're actually returning is an XML doc... which is represented in ColdFusion as a structure, though a CFC won't understand it as such.

Trying assembling a true string, rather than an XML doc. You should be able to do this fairly easily by substituting CFSAVECONTENT where your CFXML tags are:

<cfcomponent
  displayName=&quot;Detail of an Individual Account&quot;
  hint=&quot;Returns the detail of a single individual account&quot; >

<cffunction
  name=&quot;IndividualAccountDetail&quot;
  output=&quot;false&quot;
  access=&quot;remote&quot;
  displayname=&quot;Detail of an Individual Account&quot;
  hint=&quot;Returns the detail of a single individual account&quot;
  returntype=&quot;string&quot;>

<CFSAVECONTENT variable=&quot;IndividualAccounts&quot;>
<IndividualAccounts>
  <firstname>John</firstname>
  <lastname>Smith</lastname>
</IndividualAccounts>
</CFSAVECONTENT>

<cfset unParsedXML=&quot;#IndividualAccounts#&quot;>
<cfreturn unParsedXML>

</cffunction>
</cfcomponent>

and the base page stays exactly how you had it ( except, get rid of that pesky &quot;>&quot; after the webservice attribute, if it's really there ) -

<cfinvoke webservice=&quot;#application.siteurl#/WebServices/IndividualAccountDetail.cfc?WSDL&quot;
  returnvariable=&quot;userDetail&quot;
  method=&quot;IndividualAccountDetail&quot;>
</cfinvoke>

<cfset temp=xmlParse(userDetail)>
<cfdump var=&quot;#temp#&quot;>

that should do it for you.

Ah, you were right Carl, the calling page didn't like the structure, and it took a string just fine. I ended up just doin a toString() on the variable and returning that instead of doing the <cfsavecontent>, but I'd guess it works pretty much the same. Thanks a lot for the help.
