Description

The w3c spec states:
getElementsByTagName
Returns a NodeList of all the Elements with a given tag name in the order in which they would be encountered in a preorder traversal of the Document tree.

It looks that current implementation of org.apache.axiom.om.impl.dom.ElementImpl looks only at the 1st level of children and not through the tree.

Here is the code snippet

//Instantiate and parse soap message with AXIOM DOM
DocumentBuilderFactoryImpl.setDOOMRequired(true);
Document doc =DocumentBuilderFactoryImpl.newInstance().newDocumentBuilder().parse(new FileInputStream(SOAP_EXAMPLE_XML));
nl = doc.getDocumentElement().getElementsByTagName("return");
System.out.println("AXIOM DOM XML Parser found " + nl.getLength() + " element(s)"); //AXIOM DOM XML Parser found 0 element(s)

// Instantiate and parse document with xerces
System.getProperties().setProperty("javax.xml.parsers.DocumentBuilderFactory", "org.apache.xerces.jaxp.DocumentBuilderFactoryImpl");
DocumentBuilderFactory dbf = DocumentBuilderFactory.newInstance();
dbf.setNamespaceAware(true);
doc = dbf.newDocumentBuilder().parse(new FileInputStream(SOAP_EXAMPLE_XML));
nl = doc.getDocumentElement().getElementsByTagName("return");
System.out.println("XERCES XML Parser found " + nl.getLength() + " element(s)"); // XERCES XML Parser found found 1 element(s)

SOAP_EXAMPLE_XML.file:
