Details

xslHandleDebugger ()

void	xslHandleDebugger		(xmlNodePtr cur, 
					 xmlNodePtr node, 
					 xsltTemplatePtr templ, 
					 xsltTransformContextPtr ctxt)

If either cur or node are a breakpoint, or xslDebugStatus in state where debugging must occcur at this time then transfer control to the xslDebugBreak function

`cur`:	source node being executed
`node`:	data node being processed
`templ`:	temlate that applies to node
`ctxt`:	the xslt transform context

xsltApplyImports ()

					 xmlNodePtr contextNode, 
					 xmlNodePtr inst, 
					 xsltElemPreCompPtr comp)

`ctxt`:	an XSLT transformation context
`contextNode`:	the current node in the source tree.

xsltApplyOneTemplate ()

void	xsltApplyOneTemplate		(xsltTransformContextPtr ctxt, 
					 xmlNodePtr contextNode, 
					 xmlNodePtr list, 
					 xsltTemplatePtr templ, 
					 xsltStackElemPtr params)

Processes a sequence constructor on the current node in the source tree. @params are the already computed variable stack items; this function pushes them on the variable stack, and pops them before exiting; it's left to the caller to free or reuse @params afterwards. The initial states of the variable stack will always be restored before this function exits. NOTE that this does *not* initiate a new distinct variable scope; i.e. variables already on the stack are visible to the process. The caller's side needs to start a new variable scope if needed (e.g. in exsl:function). @templ is obsolete and not used anymore (e.g. <exslt:function> does not provide a @templ); a non-NULL @templ might raise an error in the future. BIG NOTE: This function is not intended to process the content of an xsl:template; it does not expect xsl:param instructions in @list and will report errors if found. Called by: - xsltEvalVariable() (variables.c) - exsltFuncFunctionFunction() (libexsl/functions.c)
