Hi,

How can I read xml file using web services?

Here is my cfc web services: (I just want to see how to read the xml file)

<cfcomponent>

  <cffunction name="getBooks" access="remote" returntype="string" output="no">

    <cfargument name="xmlObject" type="xml" required="yes" >

   

    <cfset BookResponse = "">

    <cfset var arrIndx = "">

    <cftry>

        <cfloop from="1" to="#ArrayLen(arguments.xmlObject.XmlChildren)#" index="arrIndx">

            <cfset BookResponse= arguments.xmlObject.XmlChildren[arrIndx].XmlName>

        </cfloop>

      <cfcatch type="any">

          <cfset BookResponse= "#cfcatch.message# #cfcatch.detail#">

     </cfcatch>

   </cftry>

<cfreturn BookResponse>

  </cffunction>

</cfcomponent>

Here my code to test the web services:

1. Define the xml

<!--- Setup some XML to work with --->

<cfsavecontent variable="XMLFile"><?xml version="1.0"?>

<root>

<header>

<user>1</user>

</header>

<book>

<isbn>0321330110</isbn>

<title>Macromedia ColdFusion MX 7 Certified Developer Study Guide</title>

<author>Ben Forta</author>

</book>

<header>

<user>2</user>

</header>

<book>

<isbn>0596004206</isbn>

<title>Learning XML, Second Edition</title>

<author>Erik Ray</author>

</book>

<header>

<user>3</user>

</header>

<book>

<isbn>0782140297</isbn>

<title>Coldfusion MX Developer's Handbook</title>

<author>Raymond Camden</author>

</book>

</root>

</cfsavecontent>

2.Invoke the web services

<cfinvoke

   method="getBooks"

   returnvariable="rawXMLBookList"

   webservice="http://localhost/Hoteleria/webServices/books.cfc?wsdl">

  

   <cfinvokeargument name="xmlObject" value="#XMLFile#">

</cfinvoke>

<!---<cfset XMLDocResult = XmlParse(rawXMLBookList)>

<cfdump var="#XMLDocResult#">--->

<cfdump var="#rawXMLBookList#' >

3. Error: Element XMLOBJECT.XMLCHILDREN is undefined in ARGUMENTS.

I try also using XMLParse without luck.

Any ideas?

Thanks

    Correct answer BKBK

    I am back to this XML issue.

    I am getting this:

    Element XMLROOT is undefined in XMLOBJECT.

    Something is not clicking here.

    Any ideas?

    Thanks for your help!


    Sorry about that. It did work for me!

    What about doing it on the basis of strings, as follows:

    books.cfc

    <cfcomponent>

      <cffunction name="getAuthors" access="remote" returntype="string" output="yes">

        <cfargument name="xmlString" type="string" required="yes" >

       

       <cfset var xmlObject = "">

       <cfset var rootChildren = "">

       <cfset var authors = "">

       <cfset var arrIndx = "">

         

        <cfxml variable="xmlObject"><cfoutput>#arguments.xmlString#</cfoutput></cfxml>

        <cfset rootChildren = xmlObject.xmlRoot.xmlChildren>

       

        <cftry>

           

            <cfloop from="1" to="#ArrayLen(rootChildren)#" index="arrIndx">

                <!--- 'Author' elements are in 'book'. The 'book' elements are even-numbered --->

                <cfif arrIndx mod 2 is 0>

                    <cfset authors = authors & chr(10) & chr(13) & rootChildren[arrIndx].author.XmlText>

                  </cfif>

           </cfloop>

          <cfcatch type="any">

              <cfset authors = "#cfcatch.message# #cfcatch.detail#">

         </cfcatch>

       </cftry>

      <cfreturn authors>

      </cffunction>

    </cfcomponent>

    testPage.cfm

    <cfsavecontent variable="XMLFile"><root>

    Looks like is not passing the XML doc.

    I try this in my function: <cfset BookResponse = #xmlObject#>

    Just to see if I can see the XML, I am getting this:  [#document: null]

    Any ideas?

    There are few things you can improve, for example, using cfxml to pass an XML object, rather than cfsavecontent which passes a string. The following ilustrates this and other points:

    books.cfc

    <cfcomponent>

      <cffunction name="getAuthors" access="remote" returntype="string" output="no">

        <cfargument name="xmlObject" type="xml" required="yes" >

      

        <cfset var authors = "">

        <cfset var arrIndx = "">

        <cftry>

            <cfloop from="1" to="#ArrayLen(arguments.xmlObject.XmlRoot["root"].XmlChildren)#" index="arrIndx">

                <!--- 'Author' elements are in 'book'. The 'book' elements are even-numbered --->

                <cfif arrIndx mod 2 is 0>

                    <cfset authors = authors & chr(10) & chr(13) & arguments.xmlObject.XmlRoot["root"].XmlChildren[arrIndx].author.XmlText>

                  </cfif>

           </cfloop>

          <cfcatch type="any">

              <cfset authors = "#cfcatch.message# #cfcatch.detail#">

         </cfcatch>

       </cftry>

      <cfreturn authors>

      </cffunction>

    </cfcomponent>

    testPage.cfm

    <!--- Setup some XML to work with --->

    <cfxml variable="XMLFile"><root>

    <header>
