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 |

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 |

| 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 |

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 |
