Parse xml type file

I have an xml-type document:

<configuration>

    <appSettings>

        <add key="title" value="Donny" />

        <add key="updaterApplication" value="Updater v4.3" />

    </appSettings>

</configuration>

And I need to modify a particular entry, e.g. the value="Updater v4.3" to value="Updater v4.4", when add key="updaterApplication".

I tried with:

import xml.etree.ElementTree as ET



tree = ET.parse(my_file_name)

root = tree.getroot()

tkr_itms = root.findall('appSettings')

for elm in tkr_itms[0]:

    print(elm)

    print(elm.attributes)

    print(elm.value)

    print(elm.text)

But can't get to address the content between '< ... />'.

I see you figured out that the "content between '< ... />' " are attributes.

An alternative to iterating over add elements and checking the value of the key attribute is to check the attribute value in a predicate.

Example...

Python

import xml.etree.ElementTree as ET



tree = ET.parse("my_file_name")

root = tree.getroot()

root.find('appSettings/add[@key="updaterApplication"]').attrib["value"] = "Updater v4.4"



print(ET.tostring(root).decode())

Output

<configuration>

    <appSettings>

        <add key="title" value="Donny" />

        <add key="updaterApplication" value="Updater v4.4" />

    </appSettings>

</configuration>

I see you figured out that the "content between '< ... />' " are attributes.

An alternative to iterating over add elements and checking the value of the key attribute is to check the attribute value in a predicate.

Example...

Python

import xml.etree.ElementTree as ET



tree = ET.parse("my_file_name")

root = tree.getroot()

root.find('appSettings/add[@key="updaterApplication"]').attrib["value"] = "Updater v4.4"



print(ET.tostring(root).decode())

Output

<configuration>

    <appSettings>

        <add key="title" value="Donny" />

        <add key="updaterApplication" value="Updater v4.4" />

    </appSettings>

</configuration>
