Question

i’m iterating xml node values, which i get from xpath query. And i need to assign a reference to some node value.

Here what i want to to:

from lxml import etree

doc = etree.fromstring(some_xml)
nodes = doc.xpath('some_query')
for node in nodes:
    if node.text == 'smth':
        #there i need to assign reference
        reference = node.text

#after iterating i need to that change the node value
reference = 'hello world'

is there a way to do it in python?

thanks!

Answer 1

store a reference to the actual node instead:

from lxml import etree

doc = etree.fromstring(some_xml)
nodes = doc.xpath('some_query')
for node in nodes:
    if node.text == 'smth':
        reference = node

reference.text = 'hello world'
