Description

Details

Structure xmlSaveCtxt

struct _xmlSaveCtxt {
The content of this structure is not made public by the API.
} xmlSaveCtxt;


Typedef xmlSaveCtxtPtr

xmlSaveCtxt * xmlSaveCtxtPtr;


Enum xmlSaveOption

enum xmlSaveOption {
    XML_SAVE_FORMAT = 1 /* format save output */
    XML_SAVE_NO_DECL = 2 /* drop the xml declaration */
    XML_SAVE_NO_EMPTY = 4 /* no empty tags */
    XML_SAVE_NO_XHTML = 8 /* disable XHTML1 specific rules */
    XML_SAVE_XHTML = 16 /* force XHTML1 specific rules */
    XML_SAVE_AS_XML = 32 /* force XML serialization on HTML doc */
    XML_SAVE_AS_HTML = 64 /*  force HTML serialization on XML doc */
};


xmlSaveClose ()

int	xmlSaveClose			(xmlSaveCtxtPtr ctxt)

Close a document saving context, i.e. make sure that all bytes have been output and free the associated data.

ctxt:a document saving context
Returns:the number of byte written or -1 in case of error.

xmlSaveDoc ()

long	xmlSaveDoc			(xmlSaveCtxtPtr ctxt, 
xmlDocPtr doc)

Save a full document to a saving context TODO: The function is not fully implemented yet as it does not return the byte count but 0 instead

ctxt:a document saving context
doc:a document
Returns:the number of byte written or -1 in case of error

xmlSaveFlush ()

int	xmlSaveFlush			(xmlSaveCtxtPtr ctxt)

Flush a document saving context, i.e. make sure that all bytes have been output.

ctxt:a document saving context
Returns:the number of byte written or -1 in case of error.

xmlSaveSetAttrEscape ()

int	xmlSaveSetAttrEscape		(xmlSaveCtxtPtr ctxt, 
xmlCharEncodingOutputFunc escape)

Set a custom escaping function to be used for text in attribute content

ctxt:a document saving context
escape:the escaping function
Returns:0 if successful or -1 in case of error.

xmlSaveSetEscape ()

int	xmlSaveSetEscape		(xmlSaveCtxtPtr ctxt, 
xmlCharEncodingOutputFunc escape)

Set a custom escaping function to be used for text in element content

ctxt:a document saving context
escape:the escaping function
Returns:0 if successful or -1 in case of error.

xmlSaveToBuffer ()

xmlSaveCtxtPtr	xmlSaveToBuffer		(xmlBufferPtr buffer, 
const char * encoding,
int options)

Create a document saving context serializing to a buffer with the encoding and the options given

buffer:a buffer
encoding:the encoding name to use or NULL
options:a set of xmlSaveOptions
Returns:a new serialization context or NULL in case of error.

xmlSaveToFd ()

xmlSaveCtxtPtr	xmlSaveToFd		(int fd, 
const char * encoding,
int options)

Create a document saving context serializing to a file descriptor with the encoding and the options given.

fd:a file descriptor number
encoding:the encoding name to use or NULL
options:a set of xmlSaveOptions
Returns:a new serialization context or NULL in case of error.

xmlSaveToFilename ()

xmlSaveCtxtPtr	xmlSaveToFilename	(const char * filename, 
const char * encoding,
int options)

Create a document saving context serializing to a filename or possibly to an URL (but this is less reliable) with the encoding and the options given.

filename:a file name or an URL
encoding:the encoding name to use or NULL
options:a set of xmlSaveOptions
Returns:a new serialization context or NULL in case of error.

xmlSaveToIO ()

xmlSaveCtxtPtr	xmlSaveToIO		(xmlOutputWriteCallback iowrite, 
xmlOutputCloseCallback ioclose,
void * ioctx,
const char * encoding,
int options)

Create a document saving context serializing to a file descriptor with the encoding and the options given

iowrite:an I/O write function
ioclose:an I/O close function
ioctx:an I/O handler
encoding:the encoding name to use or NULL
options:a set of xmlSaveOptions
Returns:a new serialization context or NULL in case of error.

xmlSaveTree ()

long	xmlSaveTree			(xmlSaveCtxtPtr ctxt, 
xmlNodePtr node)

Save a subtree starting at the node parameter to a saving context TODO: The function is not fully implemented yet as it does not return the byte count but 0 instead

ctxt:a document saving context
node:the top node of the subtree to save
Returns:the number of byte written or -1 in case of error
