xslt_setopt() sets the options specified by newmask on the given processor.
The XSLT processor link identifier, created with xslt_create().
newmask is a bitmask constructed with the following constants:
XSLT_SABOPT_PARSE_PUBLIC_ENTITIES - Tell the
processor to parse public entities. By default this has been turned
XSLT_SABOPT_DISABLE_ADDING_META - Do not add
the meta tag "Content-Type" for HTML output. The default is set
during the compilation of the processor.
XSLT_SABOPT_DISABLE_STRIPPING - Suppress the
whitespace stripping (on data files only).
XSLT_SABOPT_IGNORE_DOC_NOT_FOUND - Consider
unresolved documents (the document() function) non-lethal.
Returns the number of previous mask is possible,
FALSE in case of an error.
$xh = xslt_create();
// Tell Sablotron to process public entities
// Let's also ask him to suppress whitespace stripping
xslt_setopt($xh, xslt_getopt($xh) | XSLT_SABOPT_DISABLE_STRIPPING);
