Description
Structure xmlPattern
struct _xmlPattern {
The content of this structure is not made public by the API.
} Function: xmlFreePatternvoid xmlFreePattern (xmlPatternPtr comp)
Free up the memory allocated by @comp
Function: xmlFreePatternListvoid xmlFreePatternList (xmlPatternPtr comp)
Free up the memory allocated by all the elements of @comp
Function: xmlPatternMatchint xmlPatternMatch (xmlPatternPtr comp,
xmlNodePtr node)
Test wether the node matches the pattern
| comp: | the precompiled pattern | | node: | a node | | Returns: | 1 if it matches, 0 if it doesn't and -1 in case of failure |
Function: xmlPatterncompilexmlPatternPtr xmlPatterncompile (const xmlChar * pattern,
xmlDict * dict,
int flags,
const xmlChar ** namespaces)
Compile a pattern.
| pattern: | the pattern to compile | | dict: | an optional dictionnary for interned strings | | flags: | compilation flags, undefined yet | | namespaces: | the prefix definitions, array of [URI, prefix] or NULL | | Returns: | the compiled for of the pattern or NULL in case of error |
