# This script is used to split the jdiff xml into several smaller xml files
|
|
# so that we could avoid the xml resource limit in Android platform.
|
|
#
|
|
# Usage:
|
|
# android_api_description.py xmlfile tagname
|
|
#
|
|
# The script will do the following:
|
|
# 1. Read the xml file and generate DOM tree
|
|
# 2. Generate xml file for each tagname.
|
|
#
|
|
# Example:
|
|
# xml source:
|
|
# <Root>
|
|
# <A name="i">
|
|
# <B>1</B>
|
|
# <B>2</B>
|
|
# </A>
|
|
# <A name="ii">
|
|
# <B>3</B>
|
|
# </A>
|
|
# </Root>
|
|
#
|
|
# when the tagname is specified as A, it will generate two xml files:
|
|
# first one's source:
|
|
# <Root>
|
|
# <A name="i">
|
|
# <B>1</B>
|
|
# <B>2</B>
|
|
# </A>
|
|
# </Root>
|
|
# second one's source:
|
|
# <Root>
|
|
# <A name="ii">
|
|
# <B>3</B>
|
|
# </A>
|
|
# </Root>
|
|
#
|
|
# when the tagname is specified as B, it will generated three xml files:
|
|
# first one's source:
|
|
# <Root>
|
|
# <A name="i">
|
|
# <B>1</B>
|
|
# </A>
|
|
# </Root>
|
|
# second one's source:
|
|
# <Root>
|
|
# <A name="i">
|
|
# <B>2</B>
|
|
# </A>
|
|
# </Root>
|
|
# third one's source:
|
|
# <Root>
|
|
# <A name="ii">
|
|
# <B>3</B>
|
|
# </A>
|
|
# </Root>
|
|
#
|
|
# NOTE:
|
|
# 1. Currently just suppor the top level element
|
|
# 2. Use the name attribute of the specified element as the file name
|
|
# 3. Currently will remove all the doc element. - workaround for jdiff xml
