Description
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
}

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 |

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 |
Function: xmlC14NDocSaveToint 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 |

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 | | is_visible_callback: | the function to use to determine is node visible or not | | user_data: | the first parameter for @is_visible_callback function (in most cases, it is nodes set) | | 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 |
Function type: xmlC14NIsVisibleCallbackFunction 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 |
