Hi ,
I am trying to parse a xml file and read values for it. For this i am
trying to use the DocumentBuilderFactory.
The xml i am trying to read is :
<?xml version='1.0' encoding='utf-8'?>
<Mydata>
<name>QuickSanity</name>
<machine_name>155.35.3.79,155.63.3.89,155.62.3.91</machine_name>
</Mydata>
I want to read the data in tag's <name> , <machine_name> (the array of ip
address ). I want to read these values and store them in
variables so that i can use them in my stax job later on.
I am parsing them this way:
<?xml version="1.0" encoding="UTF-8" standalone="no"?>
<!DOCTYPE stax SYSTEM "stax.dtd">
<stax>
<defaultcall function="Main"/>
<function name="Main">
<sequence>
<!-- Assign the file name of a STAX xml document you want to parse -->
<call function="'parseXML'">'c:/MyXml.xml'</call>
<script>
document = STAXResult
<I am not sure sure how to use the document builder API to get the
xml files values here>
msg = '%s\nFound %s element ' % (msg,
root.getElementsByTagName("name"))
for i in range(children.getLength()):
thisChild = children.item(i);
if (thisChild.getNodeType() == Node.ELEMENT_NODE and
thisChild.getNodeName() == 'defaultcall'):
msg = '%s\nFound defaultcall element' % (msg)
elif thisChild.getNodeType() == Node.COMMENT_NODE:
# Do nothing
continue
elif thisChild.getNodeType() == Node.ELEMENT_NODE:
msg = '%s\nFound %s element ' % (msg, thisChild.getNodeName())
</script>
<message>'Some parsed data: %s' % (msg)</message>
<log>'Some parsed data: %s' % (msg)</log>
</sequence>
</function>
