I dont get the Text value from the element i am trying to work on.

results = doc.getElementsByTagName("G_TRANSACTIONS")
def getText(nodelist):
    rc = []
    for node in nodelist:
        if node.nodeType == node.TEXT_NODE:
            rc.append(node.data)
    return ''.join(rc)
for result in results:
    for element in result.getElementsByTagName("INVOICE_NUMBER"):
