I have an xml file - here is a snippet..
<gmd_fileIdentifier>
<gco_CharacterString>{0328cb65-b564-495a-b17e-e49e04864ab7}</gco_CharacterString>
</gmd_fileIdentifier>
<gmd_identifier>
<gmd_RS_Identifier>
<gmd_authority gco_nilReason="missing" />
<gmd_code>
<gco_CharacterString>0000</gco_CharacterString>
</gmd_code>
<gmd_codeSpace xmlns:gml="" xmlns:msxsl="urn:schemas-microsoft-com:xslt">
<gco_CharacterString>test</gco_CharacterString>
</gmd_codeSpace>
</gmd_RS_Identifier>
</gmd_identifier>
What I want to do is change the value of 0000 which is currently in the tag, to the gmd_fileIdentifier character string {0328cb65-b564-495a-b17e-e49e04864ab7}.
I can access the values, using the following python code, but how do I set the value? Current code
import os, sys
from lxml import etree
myXML = r"D:\test.xml"
tree = etree.parse(myXML)
root = tree.getroot()
root.xpath("//gmd_fileIdentifier/gco_CharacterString/text()")
print fileID
code = root.xpath("//gmd_identifier/gmd_RS_Identifier/gmd_code/gco_CharacterString/text()")
print code
Thanks

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! :)
