Generate random numbers and update in XML file using Robot Framework - python-3.x

Question

I've two XML files in which I manually change the values before proceeding with further evaluation. I would like to know how should I be able to update the values in the XML file using Robot Framework.
I've used faker library to generate random number but I don't know how to update them in XML. The first XML file is something like this:
<dns:ManageRequest>
<SPResource>
<ID>ORD452257337191</ID>
<interactionDate>2016-09-20T02:35:30Z</interactionDate>
<orderType>Connect</orderType>
<SPResourceComprisedOf>
<DescribedBy>
<value>CLI0000000000191</value>
<Characteristic>
<ID>clientID</ID>
</Characteristic>
</DescribedBy>
<DescribedBy>
<value>TOW566105009191</value>
<Characteristic>
<ID>ticketOfWorkId</ID>
</Characteristic>
</DescribedBy>
</SPResourceComprisedOf>
</SPResource>
</dns:ManageRequest>
and the second xml file looks like this:
<dns:ManageOrder>
<FieldWork>
<ID>WOR140618136785</ID>
<Priority>
<priorityValues>45</priorityValues>
</Priority>
<baseRevisionNumber>-1</baseRevisionNumber>
<FieldWorkSpecifiedBy>
<ID>Activation</ID>
<version>1.0.5</version>
<type>WorkOrder Specification</type>
</FieldWorkSpecifiedBy>
<FieldWorkOverview>
<DescribedBy>
<value>WRQ140618136785</value>
<Characteristic>
<ID>Work Request ID</ID>
<type>Overview</type>
</Characteristic>
</DescribedBy>
<DescribedBy>
<value>ORD452257337191</value>
<Characteristic>
<ID>Reference ID</ID>
<type>Overview</type>
</Characteristic>
</DescribedBy>
</FieldWorkOverview>
</FieldWork>
</dns:ManageOrder>
In the firs XML file the values of ORD, CLI & TOW needs to be changed and in the second XML file WOR & WRQ need to be changed but the value of ORD in the second file needs to same as the value of ORD in first file.
I really appreciate any help, because I am really lost in this now :( Thanks!

Answer 1

you can use lxml library.
Link: https://pypi.org/project/lxml/
This is example for edit element ID with your value ORD452257337191 to value '123456'.
Code:
${file}= get file ${path_to_file} encoding=UTF-8
${xml_file}= parse xml ${file}
set element text ${xml_file} 123456 xpath=ID
save xml ${xml_file} ${path_to_file} encoding=UTF-8
