I looked into the API, and I found:
- the field xsltTransformContext { ...; xsltTransformState state;
...; } can be set to XSLT_STATE_STOPPED
- the macro CHECK_STOPPED* which should be used in libxslt code to
check if the execution should be stopped.
So I should able to stop xsl transformation by changing the state to
XSLT_STATE_STOPPED right ?
Thanks.
