Renaming request nodes

One way to do it:

Response XML

<info>
   <item index="1">
      <itemContent index="1">asdfasd</itemContent>
      <itemContent index="2">wertywe</itemContent>
   </item>
   <item index="2">
      <itemContent index="1">ae344qwer</itemContent>
      <itemContent index="2">w64534</itemContent>
   </item>
</info>

Groovy script to rename the first node (adapted from http://stackoverflow.com/a/4956151:)

import javax.xml.transform.Transformer
import javax.xml.transform.TransformerFactory
import javax.xml.transform.OutputKeys
import javax.xml.parsers.DocumentBuilderFactory
import javax.xml.parsers.DocumentBuilder 
import org.w3c.dom.Document
import org.xml.sax.InputSource
import javax.xml.transform.dom.DOMSource
import javax.xml.transform.stream.StreamResult

def gu = new com.eviware.soapui.support.GroovyUtils( context )
def resp = context.expand( '${HTTP Test Request#Response#/info/item[1]}' )

// parse String as DOM
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
DocumentBuilder db = dbf.newDocumentBuilder();
Document doc = db.parse(new InputSource(new StringReader(resp)));

// modify DOM
doc.renameNode(doc.getDocumentElement(), null, "myItem");

// output DOM as String
Transformer transformer = TransformerFactory.newInstance().newTransformer();
StringWriter sw = new StringWriter();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.transform(new DOMSource(doc), new StreamResult(sw));
def newNode = sw.toString();
return newNode

Request with property expansion:

<newInfo>${Groovy Script#result}</newInfo>

Expanded request with renamed node:

<newInfo>
   <myItem index="1">
      <itemContent index="1">asdfasd</itemContent>
      <itemContent index="2">wertywe</itemContent>
   </myItem>
</newInfo>

Hi M McDonald,

Thank you for the response. However, was hoping this could be done by manipulating a request object with data already in it. I.e. take the node segment, loop through and rename, and then persist changes.

I tried the following....

def groovyUtils = new com.eviware.soapui.support.GroovyUtils( context )
def requestHolder = groovyUtils.getXmlHolder("updateRequest#Request")
def requestNode = requestHolder.getDomNode("//*:updateRequest[1]")
def requestDoc = requestHolder.getDomNode("//*:updateRequest[1]/ns3:valuation").getOwnerDocument()
for (int i = 0; i < requestDoc.getLength(); i++) {
def node = requestDoc.item(i)
requestDoc.renameNode(node, requestNode.getNamespaceURI(), "ns22:data")
}
requestHolder.updateProperty(true)

Ended with "java.lang.RuntimeException: DOM Level 3 Not implemented" error.

Any ideas?

OK, this one changes matching nodes in an existing request:

import javax.xml.transform.Transformer
import javax.xml.transform.TransformerFactory
import javax.xml.transform.OutputKeys
import javax.xml.parsers.DocumentBuilderFactory
import javax.xml.parsers.DocumentBuilder 
import org.w3c.dom.Document
import org.xml.sax.InputSource
import javax.xml.transform.dom.DOMSource
import javax.xml.transform.stream.StreamResult
import org.apache.xpath.XPathAPI
import org.apache.xml.dtm.ref.DTMNodeList

def request = context.expand( '${Test Request#Request}' )

Document doc = DocumentBuilderFactory.newInstance().newDocumentBuilder().parse(new InputSource(new StringReader(request)));
DTMNodeList nodes = XPathAPI.selectNodeList(doc.getFirstChild(), "/info/item");
for (node in nodes) { 
 doc.renameNode(node, null, 'myItem')
}

Transformer transformer = TransformerFactory.newInstance().newTransformer();
StringWriter sw = new StringWriter();
transformer.setOutputProperty(OutputKeys.OMIT_XML_DECLARATION, "yes");
transformer.transform(new DOMSource(doc), new StreamResult(sw));
def newRequest = sw.toString();
testRunner.testCase.getTestStepByName('Test Request').httpRequest.requestContent = newRequest

Hi McDonald,

That script has got me further. However, i need the name spaces of the nodes being changed, changed as well. This was not straight forward when I tried implementing that functionality.
However, your script did give me ideas. Thanks

I have managed to get functionality required using a hack - now that I know how to set the request object after manipulation is done.

I treat the request as a plain string and call replaceAll.

def request = context.expand( '${updateRequest#Request}' ).toString()
request = request.replaceAll("ns3:valuation", "ns22:data")
def tc = testRunner.testCase;
tc.getTestStepByName('updateRequest').httpRequest.requestContent = request
def result = null //to stop the groovy information pop-up

This will get me over the line. I am aware of the risk of other data being changed as a result, but I am only changing namespace:nodename type combos. So, other data should be relatively safe. Please advise if there is any other risk or problem with doing it this way.

Thanks again, much appreciated,
TestRanger
