title: How to iterate through the org.w3c.dom.NodeList using jython?
body: <p>I'm using org.w3c.dom to process some xml documents. And I'm using jython 2.5.1 to implement it.</p>
  
  <p>Part of my xml document (EmployeeInfo.xml) is like:</p>
  
  <pre><code>&lt;employees&gt;
      &lt;employee id="1"&gt;
        &lt;name&gt;ABC&lt;/name&gt;
        &lt;title&gt;Software Engineer&lt;/title&gt;
      &lt;/employee&gt; 
      &lt;employee id="2"&gt;
        &lt;name&gt;DEF&lt;/name&gt;
        &lt;title&gt;Systems Engineer&lt;/title&gt;
      &lt;/employee&gt;
      &lt;employee id="3"&gt;
        &lt;name&gt;GHI&lt;/name&gt;
        &lt;title&gt;QA Engineer&lt;/title&gt;
      &lt;/employee&gt;
      ......
  &lt;/employees&gt;
  </code></pre>
  
  <p>And my jython code for reading in and parsing xml is like:</p>
  
  <pre><code>import sys, logging
  logging.basicConfig(level=logging.INFO)
  
  from java.io import File
  from javax.xml.parsers import DocumentBuilder
  from javax.xml.parsers import DocumentBuilderFactory
  from org.w3c.dom import Document
  from org.w3c.dom import Element
  from org.w3c.dom import Node
  from org.w3c.dom import NodeList
  
  // ... some code 
  
  file = "C:/Users/Adminstrator/Doc/EmployeeInfo.xml"
  doc = File(file)
  if doc.exists():
      docFactory = DocumentBuilderFactory.newInstance()
      docFactory.setNamespaceAware(True)
      docBuilder = docFactory.newDocumentBuilder()
  
      if doc.endswith(".xml"):
          logging.info(" -- Reading " + doc)
          employeeDoc = docBuilder.parse(doc)
  
          if employeeDoc != None:
              employees = employeeDoc.getElementsByTagNameNS("*","employee")
              if employees != None:
                  for employee in employees:
                      logging.info(employee.getChildNodes().getLength())
              else:
                  logging.warn("Failed to get the employee from " + doc)
          else:
              logging.warn("Failed to parse the document " + doc)
  
  else:
      logging.warn("Failed to find the specified document" + doc + ", please check the path!")
  </code></pre>
  
  <p>When I ran this script, there was an error:</p>
  
  <pre><code>TypeError: 'org.apache.xerces.dom.DeepNodeListImpl' object is not iterable
  </code></pre>
  
  <p>referring to the line:</p>
  
  <pre><code>for employee in employees:
  </code></pre>
  
  <p>It seems like it automatically treat the 'employees' as the jython's NodeList rather than org.w3c.dom.NodeList...</p>
  
  <p>I searched online regarding this issue, but I've got little regarding this issue...Could anyone here help me with this? Thanks in advance!  </p>
