The Python interpreter is interpreting the backslashes before it gets
passed to pxdom.parse(). In particular, '\b' is seen to be the backspace
character (ASCII code 8) and treated as such.

You need to pass in "proxy_pxdom_xpath\\basedataschema.xml" or use raw
strings: r"proxy_pxdom_xpath\basedataschema.xml"
