Parser for string XML files.

This object is not thread-safe and should be used for parsing a single file at

a time, only.

def Parse(self, file):
|

'''
|
|
Parses the given file and returns a dictionary mapping keys to an object
|
|
with attributes for that key, such as the value, start/end line and explicit
|
|
revisions.
|
|
|
|
In addition to the standard XML format of the strings file, this parser
|
|
supports an annotation inside comments, in one of these formats:
|
|
|
|
<!-- KEEP_PARENT name="bla" -->
|
|
<!-- KEEP_PARENT name="bla" rev="123456789012" -->
|
|
|
|
Such an annotation indicates that we're explicitly inheriting form the
|
|
master file (and the optional revision says that this decision is compatible
|
|
with the master file up to that revision).

|
|
|
