Description

Function: xsltAttrListTemplateProcess

xmlAttrPtr	xsltAttrListTemplateProcess	(xsltTransformContextPtr ctxt, 
						 xmlNodePtr target, 
						 xmlAttrPtr attrs)

Processes all attributes of a Literal Result Element. Attribute references are applied via xsl:use-attribute-set attributes. Copies all non XSLT-attributes over to the @target element and evaluates Attribute Value Templates. Called by xsltApplySequenceConstructor() (transform.c).

`ctxt`:	the XSLT transformation context
`target`:	the element where the attributes will be grafted
`attrs`:	the first attribute
`Returns`:	a new list of attribute nodes, or NULL in case of error. (Don't assign the result to @target->properties; if the result is NULL, you'll get memory leaks, since the attributes will be disattached.)

Function: xsltAttrTemplateProcess

xmlAttrPtr	xsltAttrTemplateProcess	(xsltTransformContextPtr ctxt, 
					 xmlNodePtr target, 
					 xmlAttrPtr attr)

Process one attribute of a Literal Result Element (in the stylesheet). Evaluates Attribute Value Templates and copies the attribute over to the result element. This does *not* process attribute sets (xsl:use-attribute-set).

`ctxt`:	the XSLT transformation context
`target`:	the element where the attribute will be grafted
`attr`:	the attribute node of a literal result element
`Returns`:	the generated attribute node.

Function: xsltAttrTemplateValueProcess

xmlChar *	xsltAttrTemplateValueProcess	(xsltTransformContextPtr ctxt, 
						 const xmlChar * str)

Process the given node and return the new string value.

`ctxt`:	the XSLT transformation context
`str`:	the attribute template node value
`Returns`:	the computed string value or NULL, must be deallocated by the caller.

Function: xsltAttrTemplateValueProcessNode

xmlChar *	xsltAttrTemplateValueProcessNode	(xsltTransformContextPtr ctxt, 
							 const xmlChar * str, 
							 xmlNodePtr inst)

Process the given string, allowing to pass a namespace mapping context and return the new string value. Called by: - xsltAttrTemplateValueProcess() (templates.c) - xsltEvalAttrValueTemplate() (templates.c) QUESTION: Why is this function public? It is not used outside of templates.c.

`ctxt`:	the XSLT transformation context
`str`:	the attribute template node value
`inst`:	the instruction (or LRE) in the stylesheet holding the attribute with an AVT
`Returns`:	the computed string value or NULL, must be deallocated by the caller.

Function: xsltEvalAttrValueTemplate

xmlChar *	xsltEvalAttrValueTemplate	(xsltTransformContextPtr ctxt, 
						 xmlNodePtr inst, 
						 const xmlChar * name, 
						 const xmlChar * ns)

Evaluate a attribute value template, i.e. the attribute value can contain expressions contained in curly braces ({}) and those are substituted by they computed value.

`ctxt`:	the XSLT transformation context
`inst`:	the instruction (or LRE) in the stylesheet holding the attribute with an AVT
`name`:	the attribute QName
`ns`:	the attribute namespace URI
`Returns`:	the computed string value or NULL, must be deallocated by the caller.

Function: xsltEvalStaticAttrValueTemplate

const xmlChar *	xsltEvalStaticAttrValueTemplate	(xsltStylesheetPtr style, 
						 xmlNodePtr inst, 
						 const xmlChar * name, 
						 const xmlChar * ns, 
						 int * found)

Check if an attribute value template has a static value, i.e. the attribute value does not contain expressions contained in curly braces ({})

`style`:	the XSLT stylesheet
`inst`:	the instruction (or LRE) in the stylesheet holding the attribute with an AVT
`name`:	the attribute Name
`ns`:	the attribute namespace URI
`found`:	indicator whether the attribute is present
`Returns`:	the static string value or NULL, must be deallocated by the caller.

Function: xsltEvalTemplateString

xmlChar *	xsltEvalTemplateString	(xsltTransformContextPtr ctxt, 
					 xmlNodePtr contextNode, 
					 xmlNodePtr inst)

Processes the sequence constructor of the given instruction on @contextNode and converts the resulting tree to a string. This is needed by e.g. xsl:comment and xsl:processing-instruction.

`ctxt`:	the XSLT transformation context
`contextNode`:	the current node in the source tree
`inst`:	the XSLT instruction (xsl:comment, xsl:processing-instruction)
`Returns`:	the computed string value or NULL; it's up to the caller to free the result.

Function: xsltEvalXPathPredicate

int	xsltEvalXPathPredicate		(xsltTransformContextPtr ctxt, 
					 xmlXPathCompExprPtr comp, 
					 xmlNsPtr * nsList, 
					 int nsNr)

Process the expression using XPath and evaluate the result as an XPath predicate

`ctxt`:	the XSLT transformation context
`comp`:	the XPath compiled expression
`nsList`:	the namespaces in scope
`nsNr`:	the number of namespaces in scope
`Returns`:	1 is the predicate was true, 0 otherwise

Function: xsltEvalXPathString

xmlChar *	xsltEvalXPathString	(xsltTransformContextPtr ctxt, 
					 xmlXPathCompExprPtr comp)

Process the expression using XPath and get a string

`ctxt`:	the XSLT transformation context
`comp`:	the compiled XPath expression
`Returns`:	the computed string value or NULL, must be deallocated by the caller.

Function: xsltEvalXPathStringNs

xmlChar *	xsltEvalXPathStringNs	(xsltTransformContextPtr ctxt, 
					 xmlXPathCompExprPtr comp, 
					 int nsNr, 
					 xmlNsPtr * nsList)

Process the expression using XPath, allowing to pass a namespace mapping context and get a string

`ctxt`:	the XSLT transformation context
`comp`:	the compiled XPath expression
`nsNr`:	the number of namespaces in the list
`nsList`:	the list of in-scope namespaces to use
`Returns`:	the computed string value or NULL, must be deallocated by the caller.

Function: xsltTemplateProcess

xmlNodePtr *	xsltTemplateProcess	(xsltTransformContextPtr ctxt, 
					 xmlNodePtr node)

Obsolete. Don't use it.

`ctxt`:	the XSLT transformation context
`node`:	the attribute template node
`Returns`:	NULL.
