I'm working with an XML file which represent an UML model. Here is an example of what it is:
<?xml version="1.0" encoding="utf-8"?>
<XMI xmi.version="1.1" xmlns:UML="omg.org/UML13">
<XMI.content>
<UML:Model name="Model" xmi.id="_0">
<UML:Namespace.ownedElement>
<UML:Package name="Standard" xmi.id="_5">
</UML:Package>
</UML:Namespace.ownedElement>
</UML:Model>
</XMI.content>
</XMI>
It is a Rhapsody import format.
I want to modify this XML file by using ElementTree in Python 2.5.
I have at least one problem but I found 2 consequences, here they are:
With this simple code:
import xml.etree.ElementTree as ET
tree = ET.parse('source.xml')
root = tree.getroot()
tree.write('output.xml')
The output is: (and I don't wanted any change)
<XMI xmi.version="1.1">
<XMI.content>
<ns0:Model name="FPLN_Model" xmi.id="_0" xmlns:ns0="omg.org/UML13">
<ns0:Namespace.ownedElement>
<ns0:Package name="Standard" xmi.id="_5">
</ns0:Package>
</ns0:Namespace.ownedElement>
</ns0:Model>
</XMI.content>
</XMI>
I searched about this problem and I found a topic on stackoverflow that said to add
ET.register_namespace("UML", "omg.org/UML13")
But an error occur:
AttributeError: 'module' object has no attribute 'register_namespace'
The second consequence is that with a code like the following:
for Package_Node in Temp_Node.find('UML:Package'):
I get the error: SyntaxError: expected path separator (:)
Have someone an idea to help me?
Thank you!
