Hello I'm trying to read an xml file using minidome. The xml looks
like:
<rootNode>
<project>
<name>myProj</name>
<path>/here/</path>
</project>
</rootNode>
My code looks like so:
from xml.dom.minidom import parse
dom = parse("myfile.xml")
for node in dom.getElementsByTagName("project'):
print('name: %s, path: %s \n') % (node.childNodes[0].nodeValue,
node.childNodes[1])
Unfortunately, it returns 'nodeValue as none. I'm trying to read the
value out of the node fir example name: myProj. I haven't found much
help in the documentation. Can someone point me in the right
direction?
Two issues:
In your example XML file, the first child node of the project Element
is the Text node containing the whitespace between the <project> and
<name> tags. node.childNodes[0] will select that whitespace node.
The nodeValue of an Element is null (None). In order to get the text
contents of an element, you must get the nodeValue of the Text child
node of the Element.
Like Gabriel, I would recommend using an XML library with a more
concise API than the W3C DOM (I like lxml.objectify). But if you
stick with xml.dom, use the specification as a reference:
