Detailed Description

Parse XML to handle element tags and attributes.

vtkXMLParser reads a stream and parses XML element tags and corresponding attributes. Each element begin tag and its attributes are sent to the StartElement method. Each element end tag is sent to the EndElement method. Subclasses should replace these methods to actually use the tags.

◆ InitializeParser()

virtual int vtkXMLParser::InitializeParser ( )
virtual

When parsing fragments of XML, or when streaming XML, use the following three methods:

  • InitializeParser() initializes the parser but does not perform any actual parsing.
  • ParseChunk() parses a fragment of XML; this has to match to what was already parsed.
  • CleanupParser() finishes parsing; if there were errors, it will report them.

◆ ParseChunk()

virtual int vtkXMLParser::ParseChunk ( const char *  inputString,
unsigned int  length 
)
virtual

When parsing fragments of XML, or when streaming XML, use the following three methods:

  • InitializeParser() initializes the parser but does not perform any actual parsing.
  • ParseChunk() parses a fragment of XML; this has to match to what was already parsed.
  • CleanupParser() finishes parsing; if there were errors, it will report them.

◆ CleanupParser()

virtual int vtkXMLParser::CleanupParser ( )
virtual

When parsing fragments of XML, or when streaming XML, use the following three methods:

  • InitializeParser() initializes the parser but does not perform any actual parsing.
  • ParseChunk() parses a fragment of XML; this has to match to what was already parsed.

virtual

If this is off (the default), CharacterDataHandler will be called to process text within XML Elements.

If this is on, the text will be ignored.

virtual void vtkXMLParser::SetEncoding ( const char *  )
virtual

Set and get the encoding the parser should expect (nullptr defaults to Expat's own default encoder, i.e UTF-8).

This should be set before parsing (i.e. a call to Parse()) or even initializing the parser (i.e. a call to InitializeParser())

virtual char * vtkXMLParser::GetEncoding ( )
virtual

Set and get the encoding the parser should expect (nullptr defaults to Expat's own default encoder, i.e UTF-8).
