Description
Structure xmlURI struct _xmlURI {
char * scheme : the URI scheme
char * opaque : opaque part
char * authority : the authority part
char * server : the server part
char * user : the user part
int port : the port number
char * path : the path string
char * query : the query string
char * fragment : the fragment identifier
int cleanup : parsing potentially unclean URI
} Function: xmlBuildURIxmlChar * xmlBuildURI (const xmlChar * URI, const xmlChar * base)
Computes he final URI of the reference done by checking that the given URI is valid, and building the final URI using the base URI. This is processed according to section 5.2 of the RFC 2396 5.2. Resolving Relative References to Absolute Form
URI: | the URI instance found in the document | base: | the base value | Returns: | a new URI string (to be freed by the caller) or NULL in case of error. |
Function: xmlCanonicPathxmlChar * xmlCanonicPath (const xmlChar * path)
Constructs a canonic path from the specified path.
path: | the resource locator in a filesystem notation | Returns: | a new canonic path, or a duplicate of the path parameter if the construction fails. The caller is responsible for freeing the memory occupied by the returned string. If there is insufficient memory available, or the argument is NULL, the function returns NULL. |
Function: xmlCreateURIxmlURIPtr xmlCreateURI (void)
Simply creates an empty xmlURI
Returns: | the new structure or NULL in case of error |
Function: xmlFreeURIvoid xmlFreeURI (xmlURIPtr uri)
Free up the xmlURI struct
Function: xmlNormalizeURIPathint xmlNormalizeURIPath (char * path)
Applies the 5 normalization steps to a path string--that is, RFC 2396 Section 5.2, steps 6.c through 6.g. Normalization occurs directly on the string, no new allocation is done
path: | pointer to the path string | Returns: | 0 or an error code |
Function: xmlParseURIxmlURIPtr xmlParseURI (const char * str)
Parse an URI URI-reference = [ absoluteURI | relativeURI ] [ "#" fragment ]
str: | the URI string to analyze | Returns: | a newly build xmlURIPtr or NULL in case of error |
Function: xmlParseURIReferenceint xmlParseURIReference (xmlURIPtr uri, const char * str)
Parse an URI reference string and fills in the appropriate fields of the @uri structure URI-reference = [ absoluteURI | relativeURI ] [ "#" fragment ]
uri: | pointer to an URI structure | str: | the string to analyze | Returns: | 0 or the error code |
Function: xmlPrintURIvoid xmlPrintURI (FILE * stream, xmlURIPtr uri)
Prints the URI in the stream @steam.
stream: | a FILE* for the output | uri: | pointer to an xmlURI |
Function: xmlSaveUrixmlChar * xmlSaveUri (xmlURIPtr uri)
Save the URI as an escaped string
uri: | pointer to an xmlURI | Returns: | a new string (to be deallocated by caller) |
Function: xmlURIEscapexmlChar * xmlURIEscape (const xmlChar * str)
Escaping routine, does not do validity checks ! It will try to escape the chars needing this, but this is heuristic based it's impossible to be sure.
str: | the string of the URI to escape | Returns: | an copy of the string, but escaped 25 May 2001 Uses xmlParseURI and xmlURIEscapeStr to try to escape correctly according to RFC2396. - Carl Douglas |
Function: xmlURIEscapeStrxmlChar * xmlURIEscapeStr (const xmlChar * str, const xmlChar * list)
This routine escapes a string to hex, ignoring reserved characters (a-z) and the characters in the exception list.
str: | string to escape | list: | exception list string of chars not to escape | Returns: | a new escaped string or NULL in case of error. |
Function: xmlURIUnescapeStringchar * xmlURIUnescapeString (const char * str, int len, char * target)
Unescaping routine, does not do validity checks ! Output is direct unsigned char translation of %XX values (no encoding)
str: | the string to unescape | len: | the length in bytes to unescape (or <= 0 to indicate full string) | target: | optional destination buffer | Returns: | an copy of the string, but unescaped |
