xsltInternals - internal data structures, constants and functions

Internal data structures, constants and functions used by the XSLT engine. They are not part of the API or ABI, i.e. they can change without prior notice, use carefully.

## Description

## Details

### 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(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

`fptr`: | pointer to a function

### 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_RUNTIME_EXTRA

    #define XSLT_RUNTIME_EXTRA(ctxt, nr);

Macro used to define extra information stored in the context

`ctxt`: | the transformation context
`nr`: | the index

### Macro XSLT_RUNTIME_EXTRA_FREE

    #define XSLT_RUNTIME_EXTRA_FREE(ctxt, nr);

Macro used to free extra information stored in the context

`ctxt`: | the transformation context
`nr`: | the index

### Macro XSLT_RUNTIME_EXTRA_LST

    #define XSLT_RUNTIME_EXTRA_LST(ctxt, nr);

Macro used to access extra information stored in the context

`ctxt`: | the transformation context
`nr`: | the index
