## Description

## Details

### xmlSecParseFile ()

    xmlDocPtr   xmlSecParseFile                 (const char *filename);

Loads XML Doc from file filename. We need a special version because of c14n issue. The code is copied from `xmlSAXParseFileWithData()` function.

filename : | the filename.
Returns : | pointer to the loaded XML document or NULL if an error occurs.

### xmlSecParseMemory ()

    xmlDocPtr   xmlSecParseMemory               (const xmlSecByte *buffer,
                                                 xmlSecSize size,
                                                 int recovery);

Loads XML Doc from memory. We need a special version because of c14n issue. The code is copied from `xmlSAXParseMemory()` function.

buffer : | the input buffer.
size : | the input buffer size.
recovery : | the flag.
Returns : | pointer to the loaded XML document or NULL if an error occurs.

### xmlSecParseMemoryExt ()

    xmlDocPtr   xmlSecParseMemoryExt            (const xmlSecByte *prefix,
                                                 xmlSecSize prefixSize,
                                                 const xmlSecByte *buffer,
                                                 xmlSecSize bufferSize,
                                                 const xmlSecByte *postfix,
                                                 xmlSecSize postfixSize);

Loads XML Doc from 3 chunks of memory: prefix, buffer and postfix.

prefix : | the first part of the input.
prefixSize : | the size of the first part of the input.
buffer : | the second part of the input.
bufferSize : | the size of the second part of the input.
postfix : | the third part of the input.
postfixSize : | the size of the third part of the input.
Returns : | pointer to the loaded XML document or NULL if an error occurs.

### xmlSecTransformXmlParserId

    #define     xmlSecTransformXmlParserId

The XML Parser transform klass.

### xmlSecTransformXmlParserGetKlass ()

    xmlSecTransformId xmlSecTransformXmlParserGetKlass
                                                (void);

The XML parser transform.

Returns : | XML parser transform klass.
