Description

Macro: XSLT_REGISTER_VARIABLE_LOOKUP

#define XSLT_REGISTER_VARIABLE_LOOKUP

Registering macro, not general purpose at all but used in different modules.

Function: xsltAddStackElemList

int	xsltAddStackElemList		(xsltTransformContextPtr ctxt, 
					 xsltStackElemPtr elems)

Push an element list onto the stack.

Function: xsltEvalGlobalVariables

int	xsltEvalGlobalVariables		(xsltTransformContextPtr ctxt)

Evaluates all global variables and parameters of a stylesheet. For internal use only. This is called at start of a transformation.

Function: xsltEvalOneUserParam

int	xsltEvalOneUserParam		(xsltTransformContextPtr ctxt, 
					 const xmlChar * name, 
					 const xmlChar * value)

This is normally called from xsltEvalUserParams to process a single parameter from a list of parameters. The @value is evaluated as an XPath expression and the result is stored in the context's global variable/parameter hash table. To have a parameter treated literally (not as an XPath expression) use xsltQuoteUserParams (or xsltQuoteOneUserParam). For more details see description of xsltProcessOneUserParamInternal.

Function: xsltEvalUserParams

int	xsltEvalUserParams		(xsltTransformContextPtr ctxt, 
					 const char ** params)

Evaluate the global variables of a stylesheet. This needs to be done on parsed stylesheets before starting to apply transformations. Each of the parameters is evaluated as an XPath expression and stored in the global variables/parameter hash table. If you want your parameter used literally, use xsltQuoteUserParams.

Function: xsltFreeGlobalVariables

void	xsltFreeGlobalVariables		(xsltTransformContextPtr ctxt)

Free up the data associated to the global variables its value.

Function: xsltParseGlobalParam

void	xsltParseGlobalParam		(xsltStylesheetPtr style, 
					 xmlNodePtr cur)

parse an XSLT transformation param declaration and record its value.

Function: xsltParseGlobalVariable

void	xsltParseGlobalVariable		(xsltStylesheetPtr style, 
					 xmlNodePtr cur)

Parses a global XSLT 'variable' declaration at compilation time and registers it

Function: xsltParseStylesheetCallerParam

xsltStackElemPtr	xsltParseStylesheetCallerParam	(xsltTransformContextPtr ctxt, 
							 xmlNodePtr inst)

Processes an xsl:with-param instruction at transformation time. The value is compute, but not recorded. NOTE that this is also called with an *xsl:param* element from exsltFuncFunctionFunction().

Function: xsltParseStylesheetParam

void	xsltParseStylesheetParam	(xsltTransformContextPtr ctxt, 
					 xmlNodePtr cur)

Registers a local XSLT 'param' declaration at transformation time and evaluates its value.

Function: xsltParseStylesheetVariable

void	xsltParseStylesheetVariable	(xsltTransformContextPtr ctxt, 
					 xmlNodePtr inst)

Registers a local XSLT 'variable' instruction at transformation time and evaluates its value.

Function: xsltQuoteOneUserParam

int	xsltQuoteOneUserParam		(xsltTransformContextPtr ctxt, 
					 const xmlChar * name, 
					 const xmlChar * value)

This is normally called from xsltQuoteUserParams to process a single parameter from a list of parameters. The @value is stored in the context's global variable/parameter hash table.

Function: xsltQuoteUserParams

int	xsltQuoteUserParams		(xsltTransformContextPtr ctxt, 
					 const char ** params)

Similar to xsltEvalUserParams, but the values are treated literally and are * *not* evaluated as XPath expressions. This should be done on parsed stylesheets before starting to apply transformations.

Function: xsltVariableLookup

xmlXPathObjectPtr	xsltVariableLookup	(xsltTransformContextPtr ctxt, 
						 const xmlChar * name, 
						 const xmlChar * ns_uri)

Search in the Variable array of the context for the given variable value.

Function: xsltXPathVariableLookup

xmlXPathObjectPtr	xsltXPathVariableLookup	(void * ctxt, 
						 const xmlChar * name, 
						 const xmlChar * ns_uri)

This is the entry point when a varibale is needed by the XPath interpretor.
