Change text value with lxml

Question

I have an xml file - here is a snippet..

  
    {0328cb65-b564-495a-b17e-e49e04864ab7}

        

Answer 1

You'll have to query the whole node instead of only its contents:

code = root.xpath('//gmd_identifier/gmd_RS_Identifier/gmd_code/gco_CharacterString')

Then, if it matched, just replace its text and save back to the XML file:

if code:
    # Replaces <gco_CharacterString> text
    code[0].text = '{0328cb65-b564-495a-b17e-e49e04864ab7}'
    # Save back to the XML file
    etree.ElementTree(root).write('D:\test.xml', pretty_print=True)

That's all! :)
