Refactor parse_xml function to handle external target references (Issue #1349)

[al-rahul]

The added code checks if self.target_ref exists and if it starts with a "#", which is a common way to denote external references. If both conditions are met, the method returns RTM.EXTERNAL, indicating that the target reference is external.

This change improves the robustness of our code by correctly handling and classifying external references. This will prevent potential errors or unexpected behavior when encountering such references.

Hello
I met this issue.
It could be interesting to get this fix in the main branch.

    def getinfo(self, name):
        """Return the instance of ZipInfo given 'name'."""
        info = self.NameToInfo.get(name)
        if info is None:
>           raise KeyError(
                'There is no item named %r in the archive' % name)
E           KeyError: "There is no item named 'word/#schémaglobal' in the archive"

Hello @al-rahul Thank you for the fix. Could you resolve the conflicts ? I am interested by the fix in the master branch.

I've made a pull request already, but the repo owner seems to be inactive and hasn't touched it in more than a year.
