Description

Details

Macro XSLT_REGISTER_FUNCTION_LOOKUP

#define XSLT_REGISTER_FUNCTION_LOOKUP;

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

xsltDocumentFunction ()

void	xsltDocumentFunction		(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the document() XSLT function node-set document(object, node-set?)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltElementAvailableFunction ()

void	xsltElementAvailableFunction	(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the element-available() XSLT function boolean element-available(string)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltFormatNumberFunction ()

void	xsltFormatNumberFunction	(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the format-number() XSLT function string format-number(number, string, string?)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltFunctionAvailableFunction ()

void	xsltFunctionAvailableFunction	(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the function-available() XSLT function boolean function-available(string)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltGenerateIdFunction ()

void	xsltGenerateIdFunction		(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the generate-id() XSLT function string generate-id(node-set?)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltKeyFunction ()

void	xsltKeyFunction			(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the key() XSLT function node-set key(string, object)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltRegisterAllFunctions ()

void	xsltRegisterAllFunctions	(xmlXPathContextPtr ctxt)

Registers all default XSLT functions in this context

ctxt:the XPath context

xsltSystemPropertyFunction ()

void	xsltSystemPropertyFunction	(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the system-property() XSLT function object system-property(string)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltUnparsedEntityURIFunction ()

void	xsltUnparsedEntityURIFunction	(xmlXPathParserContextPtr ctxt, 
					 int nargs)

Implement the unparsed-entity-uri() XSLT function string unparsed-entity-uri(string)

ctxt:the XPath Parser context
nargs:the number of arguments

xsltXPathFunctionLookup ()

xmlXPathFunction	xsltXPathFunctionLookup	(void * vctxt, 
						 const xmlChar * name, 
						 const xmlChar * ns_uri)

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

vctxt:a void * but the XSLT transformation context actually
name:the function name
ns_uri:the function namespace URI
Returns:the callback function or NULL if not found
