| 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 occurences 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. |
