XML file edit with Python script

Question

I need to write a Python script that reads and replaces some data in an XML file. The data that is replaced has to be read automatically from a directory (it's a file's name)

<setting name="abc" serializeAs="String">
<value>fw.version.1.1</value>

the fw.version1.1 has to be replaced with the file name from a folder.

Could use some help:)

thanks, Robert

OK, then write one. Do you have a question? – jonrsharpe Apr 26 '16 at 08:47 — jonrsharpe, Apr 26 '16 at 08:47

Assuming the XML File looks something like that test.xml:

<someXml>
<setting name="abc" serializeAs="String"/>
<value>fw.version.1.1</value>
</someXml>

To read the XML Data from File:

from lxml import etree
parser = etree.XMLParser(remove_blank_text=True)
xmlData = etree.parse('test.xml', parser )

Reading the text from the value Tag:

xmlData.xpath('//value')[0].text

Writing new text to the value Tag:

xmlData.xpath('//value')[0].text = "test"

And finally write your changes to the same (or any other) File:

xmlData.write( 'test.xml', pretty_print=True )
