## Description

### Macro: CHECK_STOPPED

    #define CHECK_STOPPED

Macro to check if the XSLT processing should be stopped. Will return from the function.

### Macro: CHECK_STOPPED0

    #define CHECK_STOPPED0

Macro to check if the XSLT processing should be stopped. Will return from the function with a 0 value.

### Macro: CHECK_STOPPEDE

    #define CHECK_STOPPEDE

Macro to check if the XSLT processing should be stopped. Will goto the error: label.

### Macro: IS_XSLT_ATTR_FAST

    #define IS_XSLT_ATTR_FAST

quick check for xslt namespace attribute

### Macro: IS_XSLT_ELEM_FAST

    #define IS_XSLT_ELEM_FAST

quick check whether this is an xslt element

### Macro: XML_CAST_FPTR

    #define XML_CAST_FPTR

Macro to do a casting from an object pointer to a function pointer without encountering a warning from gcc #define XML_CAST_FPTR(fptr) (*(void **)(&fptr)) This macro violated ISO C aliasing rules (gcc4 on s390 broke) so it is disabled now

### Macro: XSLT_CCTXT

    #define XSLT_CCTXT

get pointer to compiler context

### Macro: XSLT_FAST_IF

    #define XSLT_FAST_IF

Internal define to enable usage of xmlXPathCompiledEvalToBoolean() for XSLT "tests"; e.g. in <xsl:if test="/foo/bar">

### Macro: XSLT_GET_INTERNAL_NSMAP

    #define XSLT_GET_INTERNAL_NSMAP

get pointer to namespace map

### Macro: XSLT_HAS_INTERNAL_NSMAP

    #define XSLT_HAS_INTERNAL_NSMAP

check for namespace mapping

### Macro: XSLT_IS_RES_TREE_FRAG

    #define XSLT_IS_RES_TREE_FRAG

internal macro to test tree fragments

### Macro: XSLT_IS_TEXT_NODE

    #define XSLT_IS_TEXT_NODE

check if the argument is a text node

### Macro: XSLT_ITEM_COMMON_FIELDS

    #define XSLT_ITEM_COMMON_FIELDS

Common fields used for all items.

### Macro: XSLT_ITEM_COMPATIBILITY_FIELDS

    #define XSLT_ITEM_COMPATIBILITY_FIELDS

Fields for API compatibility to the structure _xsltElemPreComp which is used for extension functions. Note that @next is used for storage; it does not reflect a next sibling in the tree. TODO: Evaluate if we really need such a compatibility.

### Macro: XSLT_ITEM_NAVIGATION_FIELDS

    #define XSLT_ITEM_NAVIGATION_FIELDS

Currently empty. TODO: It is intended to hold navigational fields in the future.

### Macro: XSLT_ITEM_NSINSCOPE_FIELDS

    #define XSLT_ITEM_NSINSCOPE_FIELDS

The in-scope namespaces.

### Macro: XSLT_MARK_RES_TREE_FRAG

    #define XSLT_MARK_RES_TREE_FRAG

internal macro to set up tree fragments

### Macro: XSLT_MAX_SORT

    #define XSLT_MAX_SORT

Max number of specified xsl:sort on an element.

### Macro: XSLT_PAT_NO_PRIORITY

    #define XSLT_PAT_NO_PRIORITY

Specific value for pattern without priority expressed.

### Macro: XSLT_REFACTORED_KEYCOMP

    #define XSLT_REFACTORED_KEYCOMP

Internal define to enable on-demand xsl:key computation. That's the only mode now but the define is kept for compatibility

### Macro: XSLT_REFACTORED_VARS

    #define XSLT_REFACTORED_VARS

Internal define to enable the refactored variable part of libxslt

### Macro: XSLT_REFACTORED_XPATHCOMP

    #define XSLT_REFACTORED_XPATHCOMP

Internal define to enable the optimization of the compilation of XPath expressions.

### Macro: XSLT_RUNTIME_EXTRA

    #define XSLT_RUNTIME_EXTRA

Macro used to define extra information stored in the context

### Macro: XSLT_RUNTIME_EXTRA_FREE

    #define XSLT_RUNTIME_EXTRA_FREE

Macro used to free extra information stored in the context

### Macro: XSLT_RUNTIME_EXTRA_LST

    #define XSLT_RUNTIME_EXTRA_LST

Macro used to access extra information stored in the context

### Function: xsltAllocateExtra

    int	xsltAllocateExtra		(xsltStylesheetPtr style)

Allocate an extra runtime information slot statically while compiling the stylesheet and return its number

`style`: | an XSLT stylesheet
`Returns`: | the number of the slot

### Function: xsltAllocateExtraCtxt

    int	xsltAllocateExtraCtxt		(xsltTransformContextPtr ctxt)

Allocate an extra runtime information slot at run-time and return its number This make sure there is a slot ready in the transformation context

`ctxt`: | an XSLT transformation context
`Returns`: | the number of the slot

### Function: xsltCompileAttr

    void	xsltCompileAttr			(xsltStylesheetPtr style,
    					 xmlAttrPtr attr)

Precompile an attribute in a stylesheet, basically it checks if it is an attrubute value template, and if yes establish some structures needed to process it at transformation time.

`style`: | a XSLT process context
`attr`: | the attribute coming from the stylesheet.

### Function: xsltCreateRVT

    xmlDocPtr	xsltCreateRVT		(xsltTransformContextPtr ctxt)

Creates a Result Value Tree (the XSLT 1.0 term for this is "Result Tree Fragment")

`ctxt`: | an XSLT transformation context
`Returns`: | the result value tree or NULL in case of API or internal errors.

### Function: xsltDecimalFormatGetByName

    xsltDecimalFormatPtr	xsltDecimalFormatGetByName	(xsltStylesheetPtr style,
    							 xmlChar * name)

Find decimal-format by name

`style`: | the XSLT stylesheet
`name`: | the decimal-format name to find
`Returns`: | the xsltDecimalFormatPtr

### Function type: xsltElemPreCompDeallocator

    Function type: xsltElemPreCompDeallocator
    void	xsltElemPreCompDeallocator	(xsltElemPreCompPtr comp)

Deallocates an #xsltElemPreComp structure.

`comp`: | the #xsltElemPreComp to free up

### Function: xsltEvalAVT

    xmlChar *	xsltEvalAVT		(xsltTransformContextPtr ctxt,
    					 void * avt,
    					 xmlNodePtr node)

Process the given AVT, and return the new string value.

`ctxt`: | the XSLT transformation context
`avt`: | the prevompiled attribute value template info
`node`: | the node hosting the attribute
`Returns`: | the computed string value or NULL, must be deallocated by the caller.

### Function: xsltExtensionInstructionResultFinalize

    int	xsltExtensionInstructionResultFinalize	(xsltTransformContextPtr ctxt)

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.

`ctxt`: | an XSLT transformation context
`Returns`: | 0 in case of success and -1 in case of API or internal errors.

### Function: xsltExtensionInstructionResultRegister

    int	xsltExtensionInstructionResultRegister	(xsltTransformContextPtr ctxt,
    						 xmlXPathObjectPtr obj)

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().

`ctxt`: | an XSLT transformation context
`obj`: | an XPath object to be inspected for result tree fragments

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.
