public class NekoHtmlDocumentFormat
extends TextualDocumentFormat

DocumentFormat that uses Andy Clark's NekoHTML parser to parse HTML documents. It tries to render HTML in a similar way to a web browser, i.e. whitespace is normalized, paragraphs are separated by a blank line, etc. By default the text content of style and script tags is ignored completely, though the set of tags treated in this way is configurable via a CREOLE parameter.

supportsRepositioning

public Boolean supportsRepositioning()

We support repositioning info for HTML files.

Overrides:

supportsRepositioning in class DocumentFormat

unpackMarkup

public void unpackMarkup(Document doc)
                  throws DocumentFormatException

Old-style unpackMarkup, without repositioning info.

Overrides:

unpackMarkup in class TextualDocumentFormat

Throws:

DocumentFormatException

unpackMarkup

public void unpackMarkup(Document doc,
                         RepositioningInfo repInfo,
                         RepositioningInfo ampCodingInfo)
                  throws DocumentFormatException

Unpack the markup in the document. This converts markup from the native format into annotations in GATE format. If the document was created from a String, then is recomandable to set the doc's sourceUrl to null. So, if the document has a valid URL, then the parser will try to parse the XML document pointed by the URL.If the URL is not valid, or is null, then the doc's content will be parsed. If the doc's content is not a valid XML then the parser might crash.

Overrides:

unpackMarkup in class TextualDocumentFormat

Parameters:

doc - The gate document you want to parse. If doc.getSourceUrl() returns null then the content of doc will be parsed. Using a URL is recomended because the parser will report errors corectlly if the document is not well formed.

Throws:

DocumentFormatException

init

public Resource init()
              throws ResourceInstantiationException

Initialise this resource, and return it.

Specified by:

init in interface Resource

Overrides:

init in class TextualDocumentFormat

Throws:

ResourceInstantiationException
