                </presentation:notes>
            </draw:page>

Ultimately, i want to get the value of all text:p elements or their child if they exist such as <text:span ...>.

My python code is :

   ostr = self.m_odf.read('content.xml')
    doc = ET.fromstring(ostr)
    self.pages = doc.findall("//*[@name='draw:page']")#'text:p')

I want to first get a list of the draw:page nodes and then search inside these nodes the 'text:p' elements.

My code returns an error "SyntaxError: cannot use absolute path on element".

Im not used to these tag:x syntax in xml so i dont find how to parse it with xpath ("//*[@name='draw:page']") doesnt seem to work.

Could you help me please?

  • I would recommend reproducing your error with a barebones version of your input xml. It could also help others lend a hand. Commented Sep 22, 2022 at 13:38
  • the xml is 87 pages long. this is only one page.... Commented Sep 22, 2022 at 13:45
  • Can you reproduce your error with a smaller version of your xml? Commented Sep 22, 2022 at 13:50
  • you can test here : freeformatter.com/xpath-tester.html with the full file (all the styles need to be loaded...) : s3.eu-west-3.amazonaws.com/pretty.xml/pretty.xml Commented Sep 22, 2022 at 14:17

In your xml there are a lot if missing namespace declarations, but surely they are on a high level in the xml-tree. If you are not able to use those namespace, you can use the local-name() function, to select elements based on there names without the namespace-prefix.

In the end you could try this XPath:

"//*[local-name()='page']//*[local-name()='p']//node()"

where the last part select all descendants (also text-nodes and element-nodes)
