I have an XML document with the following structure-

I am interested in capturing the text contained within ... and for that I wrote the following Python 3 regex code-

file = open("sample_xml.xml", "r")
xml_doc = file.read()
file.close()

body_text = re.findall(r'<bdy>(.+)</bdy>', xml_doc)

But 'body_text' is always returning an empty list. However, when I try to capture the text for the tags ... using code-

category_text = re.findall(r'(.+)', xml_doc)

This does the job.
Any idea(s) as to why the ... XML element code is not working?

Thanks!

The special character . will not match a newline, so that regex will not match a multiline string.

You can change this behavior by specifying the DOTALL flag. To specify that flag you can include this at the start of your regular expression: (?s)

More information on Python's regular expression syntax can be found here: https://docs.python.org/3/library/re.html#regular-expression-syntax

You can use re.DOTALL

category_text = re.findall(r'<bdy>(.+)</bdy>', xml_doc, re.DOTALL)

Output:

[" Postmodernism preceded by Modernism '' Postmodernityn> Postchristianity Postmodern philosophy Postmodern architecturen> Postmodern art Postmodernist film Postmodern literature Postmodernn> music Postmodern theater Critical theory Globalization Consumerismn> "]
