xsltApplyOneTemplate()

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

xsltApplyOneTemplate: @ctxt: a XSLT process context @contextNode: the node in the source tree. @list: the nodes of a sequence constructor @templ: not used @params: a set of parameters (xsl:param) or NULL

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@templ is obsolete and not used anymore (e.g. 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.
