xsltExtensionInstructionResultFinalize: @ctxt: an XSLT transformation context

Finalizes the data (e.g. result tree fragments) created within a value-returning process (e.g. EXSLT's function). Tree fragments marked as being returned by a function are set to normal state, which means that the fragment garbage collector will free them after the function-calling process exits.

Returns 0 in case of success and -1 in case of API or internal errors.

This function is unsupported in newer releases of libxslt.

Marks the result of a value-returning extension instruction in order to avoid it being garbage collected before the extension instruction exits. Note that one still has to additionally register any newly created tree fragments (via xsltCreateRVT()) with xsltRegisterLocalRVT().

Returns 0 in case of success and -1 in case of error.

Updates ownership information of RVTs in @obj according to @val.

@val = XSLT_RVT_FUNC_RESULT for the result of an extension function, so its RVTs won't be destroyed after leaving the returning scope. @val = XSLT_RVT_LOCAL for the result of an extension function to reset the state of its RVTs after it was returned to a new scope. @val = XSLT_RVT_GLOBAL for parts of global variables.

Returns

format-number() uses the JDK 1.1 DecimalFormat class:

http://java.sun.com/products/jdk/1.1/docs/api/java.text.DecimalFormat.html

Structure:

pattern := subpattern{;subpattern} subpattern := {prefix}integer{.fraction}{suffix} prefix := '\u0000'..'\uFFFD' - specialCharacters suffix := '\u0000'..'\uFFFD' - specialCharacters integer := '#'* '0'* '0' fraction := '0'* '#'*

Notation: X* 0 or more instances of X (X | Y) either X or Y. X..Y any character from X up to Y, inclusive. S - T characters in S, except those in T

Special Characters:

Symbol Meaning 0 a digit

a digit, zero shows as absent

. placeholder for decimal separator , placeholder for grouping separator. ; separates formats.

• default negative prefix. % multiply by 100 and show as percentage ? multiply by 1000 and show as per mille X any other characters can be used in the prefix or suffix ' used to quote special characters in a prefix or suffix.

Returns a possible XPath error

xsltLoadStylesheetPI: @doc: a document to process

This function tries to locate the stylesheet PI in the given document If found, and if contained within the document, it will extract that subtree to build the stylesheet to process @doc (doc itself will be modified). If found but referencing an external document it will attempt to load it and generate a stylesheet from it. In both cases, the resulting stylesheet and the document need to be freed once the transformation is done.

Returns a new XSLT stylesheet structure or NULL if not found.
