  • Parse xml from file using etree works when reading string, but not a file

    2 answers




Attempting to parse an XML with namespaces and attributes. I wish to retrieve an element by a given attribute (id).



Documentation specifies but




[@attrib] Selects all elements that have the given attribute.



[@attrib='value'] Selects all elements for which the given attribute has the given value. The value cannot contain quotes.




neither solutions below returns an element when given an attribute name & value or when given an attribute name only



from lxml import etree
tree = etree.parse("es.xml")
root = tree.getroot()

print root.findall('file/body/trans-unit', root.nsmap)


# Unable to fetch all with attribute == id
print root.findall('file/body/trans-unit[@id]', root.nsmap)

# Unable to fetch element with id = 111
print root.find('file/body/trans-unit[@id="111"]', root.nsmap)

          I don't know how to do it with the {None: "urn:oasis:names:tc:xliff:document:1.2"} namespace of root.nsmap...



          However, if you redefine a namespace map like



          ns = {"n": "urn:oasis:names:tc:xliff:document:1.2"}


          then this works



          root.find('.//n:trans-unit[@id="111"]', ns)
