Question

I’m looking for a way to add attributes to xml tags in python. Or to create a new tag with a new attributes
for example, I have the following xml file:

<types name='character' shortName='chrs'>
....
...

</types>

and i want to add an attribute to make it look like this:

<types name='character' shortName='chrs' fullName='MayaCharacters'>
....
...
</types>

how do I do that with python? by the way. I use python and minidom for this
please help. thanks in advance

Answer 1

You can use the attributes property of the respective Node object.

For example:

from xml.dom.minidom import parseString
documentNode = parseString("<types name='character' shortName='chrs'></types>")
typesNode = documentNode.firstChild

# Getting an attribute
print typesNode.attributes["name"].value # will print "character"

# Setting an attribute
typesNode.attributes["mynewattribute"] = u"mynewvalue"
print documentNode.toprettyxml()

The last print statement will output this XML document:

<?xml version="1.0" ?>
<types mynewattribute="mynewvalue" name="character" shortName="chrs"/>
