XML.h - Xerces wrappers & convenience functions
|
|
EXAMPLE :
|
|
Simple usage:
|
|
|
|
CVFSEntityResolver *entRes=new CVFSEntityResolver(filename);
|
|
parser->setEntityResolver(entRes);
|
|
|
|
CVFSInputSource src;
|
|
if (src.OpenFile("this/is/a/vfs/path.xml")==0)
|
|
parser->parse(src);
|
|
|
|
delete entRes;
|
|
|
|
The input source object should be kept alive as long as the parser is
|
|
using its input stream (i.e. until the parse is complete). The same
|
|
goes for the entity resolver.
