Purpose of this XML Stylesheet is to implement a set of templates |
| 7 |
|
|
to translate XUpdate lingo into an intermediate xslt stylesheet |
| 8 |
|
|
which actually performs the update to the original xml document |
| 9 |
|
|
in a second step. |
| 10 |
|
|
The required glue code - written in Perl - is available in module |
| 11 |
|
|
XML::XUpdate::XSLT. Please have a look at this to port it to other |
| 12 |
|
|
languages. |
