XSLT_REGISTER_VARIABLE_LOOKUP()

#define     XSLT_REGISTER_VARIABLE_LOOKUP(ctxt)

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

ctxt :

xsltEvalGlobalVariables ()

int         xsltEvalGlobalVariables         (xsltTransformContextPtr ctxt);

Evaluate the global variables of a stylesheet. This need to be done on parsed stylesheets before starting to apply transformations

`ctxt` :	the XSLT transformation context
Returns :	0 in case of success, -1 in case of error

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

`ctxt` :	the XSLT transformation context
`params` :	a NULL terminated arry of parameters names/values tuples
Returns :	0 in case of success, -1 in case of error

xsltParseGlobalVariable ()

void        xsltParseGlobalVariable         (xsltStylesheetPtr style,
                                             xmlNodePtr cur);

parse an XSLT transformation variable declaration and record its value.

`style` :	the XSLT stylesheet
`cur` :	the "variable" element

xsltParseGlobalParam ()

void        xsltParseGlobalParam            (xsltStylesheetPtr style,
                                             xmlNodePtr cur);

parse an XSLT transformation param declaration and record its value.

`style` :	the XSLT stylesheet
`cur` :	the "param" element

xsltParseStylesheetVariable ()

void        xsltParseStylesheetVariable     (xsltTransformContextPtr ctxt,
                                             xmlNodePtr cur);

parse an XSLT transformation variable declaration and record its value.

`ctxt` :	the XSLT transformation context
`cur` :	the "variable" element

xsltParseStylesheetParam ()

void        xsltParseStylesheetParam        (xsltTransformContextPtr ctxt,
                                             xmlNodePtr cur);

parse an XSLT transformation param declaration and record its value.

`ctxt` :	the XSLT transformation context
`cur` :	the "param" element

xsltParseStylesheetCallerParam ()

xsltStackElemPtr xsltParseStylesheetCallerParam
                                            (xsltTransformContextPtr ctxt,
                                             xmlNodePtr cur);

parse an XSLT transformation param declaration, compute its value but doesn't record it.

It returns the new xsltStackElemPtr or NULL

`ctxt` :	the XSLT transformation context
`cur` :	the "param" element
Returns :

xsltAddStackElemList ()

int         xsltAddStackElemList            (xsltTransformContextPtr ctxt,
                                             xsltStackElemPtr elems);

add the new element list at this level of the stack.

`ctxt` :	xn XSLT transformation context
`elems` :	a stack element list
Returns :	0 in case of success, -1 in case of failure.

xsltFreeGlobalVariables ()

void        xsltFreeGlobalVariables         (xsltTransformContextPtr ctxt);

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

ctxt : the XSLT transformation context

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.

`ctxt` :	the XSLT transformation context
`name` :	the variable name
`ns_uri` :	the variable namespace URI
Returns :	the value or NULL if not found

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.

`ctxt` :	a void * but the the XSLT transformation context actually
`name` :	the variable name
`ns_uri` :	the variable namespace URI
Returns :	the value or NULL if not found
