/** An input stream class for VML streams, implementing the UNO interface
|
|
com.sun.star.io.XInputStream needed by the Expat XML parsers.
|
|
|
|
This stream reads the data from the input stream passed to the constructor,
|
|
and parses all XML elements for features unsupported by the current Expat
|
|
XML parser:
|
|
|
|
1) All elements that have the form '<![inst]>' where 'inst' is any string
|
|
not containing the characters '<' and '>' are stripped from the input
|
|
stream.
|
|
|
|
2) Multiple occurrences of the same attribute in an element but the last
|
|
are removed.
|
|
|
|
3) Line breaks represented by a single <br> element (without matching
|
|
</br> element) are replaced by a literal LF character.
