C# 클래스 iTextSharp.xmp.impl.XmpMetaParser

This class replaces the ExpatAdapter.cpp and does the XML-parsing and fixes the prefix. After the parsing several normalisations are applied to the XMPTree. @since 01.02.2006

Parse ( object input, ParseOptions options ) : XMPMeta

Parses the input source into an XMP metadata object, including de-aliasing and normalisation.

메소드 설명
FindRootNode ( XmlNode root, bool xmpmetaRequired, object result ) : object[]

Find the XML node that is the root of the XMP data tree. Generally this will be an outer node, but it could be anywhere if a general XML document is parsed (e.g. SVG). The XML parser counted all rdf:RDF and pxmp:XMP_Packet nodes, and kept a pointer to the last one. If there is more than one possible root use PickBestRoot to choose among them.

If there is a root node, try to extract the version of the previous XMP toolkit.

Pick the first x:xmpmeta among multiple root candidates. If there aren't any, pick the first bare rdf:RDF if that is allowed. The returned root is the rdf:RDF child if an x:xmpmeta element was chosen. The search is breadth first, so a higher level candiate is chosen over a lower level one that was textually earlier in the serialized XML.
ParseXml ( object input, ParseOptions options ) : XmlDocument

Parses the raw XML metadata packet considering the parsing options. Latin-1/ISO-8859-1 can be accepted when the input is a byte stream (some old toolkits versions such packets). The stream is then wrapped in another stream that converts Latin-1 to UTF-8.

If control characters shall be fixed, a reader is used that fixes the chars to spaces (if the input is a byte stream is has to be read as character stream).

Both options reduce the performance of the parser.
ParseXmlFromBytebuffer ( ByteBuffer buffer, ParseOptions options ) : XmlDocument

Parses XML from a byte buffer, fixing the encoding (Latin-1 to UTF-8) and illegal control character optionally.
ParseXmlFromInputStream ( Stream stream, ParseOptions options ) : XmlDocument

Parses XML from an Stream, fixing the encoding (Latin-1 to UTF-8) and illegal control character optionally.
ParseXmlFromString ( string input, ParseOptions options ) : XmlDocument

Parses XML from a string, fixing the illegal control character optionally.
XmpMetaParser ( ) : System

the DOM Parser Factory, options are set

Hidden constructor, initialises the SAX parser handler.
