Python question

[Jürgen Spitzmüller]

In order to fix bug 2520, I need to parse the external_templates files in 
lyx_pot.py.

This works, except for the HelpText. Can any Pythonist tell me how to Parse 
the content between
HelpText
        <content (multiline)>
HelpTextEnd

in the function below?

def external_l10n(input_files, output, base):
    '''Generate pot file from lib/external_templates'''
    output = open(output, 'w')
    Template = re.compile(r'^Template\s+(.*)')
    GuiName = re.compile(r'\s*GuiName\s+(.*)')
    i = -1
    for src in input_files:
        input = open(src)
        for lineno, line in enumerate(input.readlines()):
            if Template.match(line):
                (string,) = Template.match(line).groups()
            elif GuiName.match(line):
                (string,) = GuiName.match(line).groups()
-->         elif <HelpText>???
            else:
                continue
            string = string.replace('"', '')
            if string != "":
                print >> output, '#: %s:%d\nmsgid "%s"\nmsgstr ""\n' % \
                    (relativePath(src, base), lineno+1, string)
        input.close()
    output.close()
