 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 |

 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 |

 Dumps the canonized image of given XML document into the provided buffer.
