Python ElementTree default namespace?

阅读更多关于 Python ElementTree default namespace?

问题 Is there a way to define the default/unprefixed namespace in python ElementTree? This doesn't seem to work... ns = {"":"http://maven.apache.org/POM/4.0.0"} pom = xml.etree.ElementTree.parse("pom.xml") print(pom.findall("version", ns)) Nor does this: ns = {None:"http://maven.apache.org/POM/4.0.0"} pom = xml.etree.ElementTree.parse("pom.xml") print(pom.findall("version", ns)) This does, but then I have to prefix every element: ns = {"mvn":"http://maven.apache.org/POM/4.0.0"} pom = xml.etree

How do I get the full XML or HTML content of an element using ElementTree?

That is, all text and subtags, without the tag of an element itself? Having blah bleh blih I want blah bleh blih element.text returns "blah " and etree.tostring(element) returns: blah bleh blih ElementTree works perfectly, you have to assemble the answer yourself. Something like this... "".join( [ "" if t.text is None else t.text ] + [ xml.tostring(e) for e in t.getchildren() ] ) Thanks to JV amd PEZ for pointing out the errors. Edit. >>> import xml.etree.ElementTree as xml >>> s= 'blah bleh blih\n' >>> t=xml.fromstring(s) >>> "".join( [ t.text

How to find XML Elements via XPath in Python in a namespace-agnostic way?

阅读更多关于 How to find XML Elements via XPath in Python in a namespace-agnostic way?

问题 since I had this annoying issue for the 2nd time, I thought that asking would help. Sometimes I have to get Elements from XML documents, but the ways to do this are awkward. I’d like to know a python library that does what I want, a elegant way to formulate my XPaths, a way to register the namespaces in prefixes automatically or a hidden preference in the builtin XML implementations or in lxml to strip namespaces completely. Clarification follows unless you already know what I want :) Example

Elementtree setting attribute order

阅读更多关于 Elementtree setting attribute order

问题 I am trying to write a python script to standardise generic XML files, used to configure websites and website forms. However to do this I would like to either maintain the original attribute ordering of the elements, or even better be able to rearrange them in a pre-defined way. Currently most xml parsers I have tried re-write the attribute order to be alpha-numeric. As these XML files are human read/written and maintained, this isn't too useful. For example a generic element may look like
