def XML2Python.fixQuoteValue

(

match

)

Changes all characters inside of the match

Definition at line 215 of file XML2Python.py.

    '''Changes all characters inside of the match'''
    quote = match.group(2)
    for regexTup in regexList:
        quote = regexTup[0].sub( regexTup[1], quote )

def XML2Python.xml2obj

(

kwargs

)

Converts XML data into native Python object.  Takes either
file handle or string as input.  Does NOT fix illegal characters.

input source:  Exactly one of the three following is needed
filehandle     - input from file handle
contents       - input from string
filename       - input from filename

options:
filtering      - boolean value telling code whether or not to fileter
                 input selection to remove illegal XML characters
nameChangeDict - dictionaries of names to change in python object
