#define     XSLT_TODO

Macro to flag unimplemented blocks.


XSLT_STRANGE

#define     XSLT_STRANGE

Macro to flag that a problem was detected internally.


IS_XSLT_ELEM()

#define     IS_XSLT_ELEM(n)

Checks that the element pertains to XSLT namespace.

n :

IS_XSLT_NAME()

#define     IS_XSLT_NAME(n, val)

Checks the value of an element in XSLT namespace.

n :
val :

IS_XSLT_REAL_NODE()

#define     IS_XSLT_REAL_NODE(n)

xsltGetNsProp ()

Similar to xmlGetNsProp() but with a slightly different semantic

Search and get the value of an attribute associated to a node This attribute has to be anchored in the namespace specified, or has no namespace and the element is in that namespace.

This does the entity substitution. This function looks in DTD attribute declaration for FIXED or default declaration values unless DTD use has been turned off.

Returns :the attribute value or NULL if not found. It's up to the caller to free the memory.

Add template "call" to call stack

templ : current template being applied
source : the source node being processed
Returns :: 1 on sucess 0 otherwise an error may be printed if WITH_XSLT_DEBUG_BREAKPOINTS is defined
