* This module gives external access to the functions needed to create |
9
|
|
|
|
|
|
|
* and use XML::LibXML::Nodes from C functions. These functions are made |
10
|
|
|
|
|
|
|
* accessible from Perl to have cleaner dependencies. |
11
|
|
|
|
|
|
|
* The idea is to pass xmlNode * pointers (as typemapped void *) to and |
12
|
|
|
|
|
|
|
* from Perl and call the functions that turns them to and from |
13
|
|
|
|
|
|
|
* XML::LibXML::Nodes there. |

|
|
|
|
|
* Be aware that using this module gives you the ability to easily create |
16
|
|
|
|
|
|
|
* segfaults and memory leaks. |
