Enum xmlC14NMode

enum xmlC14NMode {
    XML_C14N_1_0 = 0 /* Original C14N 1.0 spec */
    XML_C14N_EXCLUSIVE_1_0 = 1 /* Exclusive C14N 1.0 spec */
    XML_C14N_1_1 = 2 /*  C14N 1.1 spec */
};

Function type xmlC14NIsVisibleCallback

int	xmlC14NIsVisibleCallback	(void * user_data, 
					 xmlNodePtr node, 
					 xmlNodePtr parent)

Signature for a C14N callback on visible nodes

`user_data`:	user data
`node`:	the current node
`parent`:	the parent node
`Returns`:	1 if the node should be included

xmlC14NDocDumpMemory ()

int	xmlC14NDocDumpMemory		(xmlDocPtr doc, 
					 xmlNodeSetPtr nodes, 
					 int mode, 
					 xmlChar ** inclusive_ns_prefixes, 
					 int with_comments, 
					 xmlChar ** doc_txt_ptr)

Dumps the canonized image of given XML document into memory. For details see "Canonical XML" (http://www.w3.org/TR/xml-c14n) or "Exclusive XML Canonicalization" (http://www.w3.org/TR/xml-exc-c14n)

`doc`:	the XML document for canonization
`nodes`:	the nodes set to be included in the canonized image or NULL if all document nodes should be included
`mode`:	the c14n mode (see @xmlC14NMode)
`inclusive_ns_prefixes`:	the list of inclusive namespace prefixes ended with a NULL or NULL if there is no inclusive namespaces (only for exclusive canonicalization, ignored otherwise)
`with_comments`:	include comments in the result (!=0) or not (==0)
`doc_txt_ptr`:	the memory pointer for allocated canonical XML text; the caller of this functions is responsible for calling xmlFree() to free allocated memory
`Returns`:	the number of bytes written on success or a negative value on fail

xmlC14NDocSave ()

int	xmlC14NDocSave			(xmlDocPtr doc, 
					 xmlNodeSetPtr nodes, 
					 int mode, 
					 xmlChar ** inclusive_ns_prefixes, 
					 int with_comments, 
					 const char * filename, 
					 int compression)

Dumps the canonized image of given XML document into the file. For details see "Canonical XML" (http://www.w3.org/TR/xml-c14n) or "Exclusive XML Canonicalization" (http://www.w3.org/TR/xml-exc-c14n)

`doc`:	the XML document for canonization
`nodes`:	the nodes set to be included in the canonized image or NULL if all document nodes should be included
`mode`:	the c14n mode (see @xmlC14NMode)
`inclusive_ns_prefixes`:	the list of inclusive namespace prefixes ended with a NULL or NULL if there is no inclusive namespaces (only for exclusive canonicalization, ignored otherwise)
`with_comments`:	include comments in the result (!=0) or not (==0)
`filename`:	the filename to store canonical XML image
`compression`:	the compression level (zlib required): -1 - libxml default, 0 - uncompressed, >0 - compression level
`Returns`:	the number of bytes written success or a negative value on fail

xmlC14NDocSaveTo ()

int	xmlC14NDocSaveTo		(xmlDocPtr doc, 
					 xmlNodeSetPtr nodes, 
					 int mode, 
					 xmlChar ** inclusive_ns_prefixes, 
					 int with_comments, 
					 xmlOutputBufferPtr buf)

Dumps the canonized image of given XML document into the provided buffer. For details see "Canonical XML" (http://www.w3.org/TR/xml-c14n) or "Exclusive XML Canonicalization" (http://www.w3.org/TR/xml-exc-c14n)

`doc`:	the XML document for canonization
`nodes`:	the nodes set to be included in the canonized image or NULL if all document nodes should be included
`mode`:	the c14n mode (see @xmlC14NMode)
`inclusive_ns_prefixes`:	the list of inclusive namespace prefixes ended with a NULL or NULL if there is no inclusive namespaces (only for exclusive canonicalization, ignored otherwise)
`with_comments`:	include comments in the result (!=0) or not (==0)
`buf`:	the output buffer to store canonical XML; this buffer MUST have encoder==NULL because C14N requires UTF-8 output
`Returns`:	non-negative value on success or a negative value on fail

xmlC14NExecute ()

int	xmlC14NExecute			(xmlDocPtr doc, 
					 xmlC14NIsVisibleCallback is_visible_callback, 
					 void * user_data, 
					 int mode, 
					 xmlChar *

c14n
