xpath expression with attribute in Element tree python

import xml.etree.ElementTree as ET
tree: ET = ET.parse(file)
tree.find('.//ns1:tag/@someattribute', ns)

is resulting in {KeyError}'@', xpath expression is correct as per my knowledge, is there any way in element tree to get attribute value directly using xpath and not using .attrib

Solution

  • The XPath expression is syntactically OK. The problem is that find() locates only elements. It cannot be used to find attributes.

    This should work:

    attr = tree.find('.//ns1:tag', ns).get('someattribute')

    With lxml, you could use the xpath() method (which returns a list):

    attr = tree.xpath('.//ns1:tag/@someattribute', namespaces=ns)[0]
