Reformat XML SOAP Response

Question

Hi,
I am creating a CF component that calls a Web service and I
would like to reformat the result. I do not have access to the
service provider to make changes so I have to make the conversion
on the client side.
The result from the service returns the field definitions for
every element then the actual data values follow. Here is an
example of the XML sent back from the service only showing two
elements.
<fieldDefinitions>
<fieldName>NAME1</fieldName>
<fieldType>STRING</fieldType>
<fieldLength>20</fieldLength>
</fieldDefinitions>
<fieldDefinitions>
<fieldName>NAME2</fieldName>
<fieldType>STRING</fieldType>
<fieldLength>40</fieldLength>
</fieldDefinitions>
<dataRows>
<value>John</value>
<value>Doe</value>
</dataRows>
I would like to reformat the XML to make the value of the
<fieldName> as the element tag then put the actual value
inside the tag. Something like this.
<name1>John</name1>
<name2>Doe</name2>
I am not exactly sure what the best method would be to
accomplish this, using the XmlNew function or maybe transforming
the output with a style sheet (XSLT).
Any suggestions would be helpful.
Thanks,
Chris

The SOAP message minus the mime headers(i.e. Content-length) is an xml file. You can parse this file using a SAX or DOM parser. The soap message will be on the request input stream. Read the soap message into a string and then create an inputSource of this string, then use a sax parser to parse this input. You can write a contenthandler to look for certain element tags and extract its content which you can then place in the response output stream. For details on using sax look at java.sun.com/xml for the xml tutorial.
hope this helps.
