      Returns:
      current track position setting
    • setTrackPosition

      public Parser setTrackPosition(boolean trackPosition)

      current ParseSettings
    • isContentForTagData

      public boolean isContentForTagData(String normalName)

    • parse

      public static Document parse(String html, String baseUri)
      Parse HTML into a Document.
      Parameters:
      html - HTML to parse

    • parseFragment

      public static List<Node> parseFragment(String fragmentHtml, Element context, String baseUri)
      Parse a fragment of HTML into a list of nodes. The context element, if supplied, supplies parsing context.
      Parameters:
      fragmentHtml - the fragment of HTML to parse
      context - (optional) the element that this HTML fragment is being parsed for (i.e. for inner HTML). This provides stack context (for implicit element creation).
      baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.
      Returns:
      list of nodes parsed from the input HTML. Note that the context element, if supplied, is not modified.
    • parseFragment

      public static List<Node> parseFragment(String fragmentHtml, Element context, String baseUri, ParseErrorList errorList)
      Parse a fragment of HTML into a list of nodes. The context element, if supplied, supplies parsing context.
      Parameters:
      fragmentHtml - the fragment of HTML to parse
      context - (optional) the element that this HTML fragment is being parsed for (i.e. for inner HTML). This provides stack context (for implicit element creation).
      baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.
      errorList - list to add errors to
      Returns:
      list of nodes parsed from the input HTML. Note that the context element, if supplied, is not modified.
    • parseXmlFragment

      public static List<Node> parseXmlFragment(String fragmentXml, String baseUri)
      Parse a fragment of XML into a list of nodes.
      Parameters:
      fragmentXml - the fragment of XML to parse
      baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.
      Returns:
      list of nodes parsed from the input XML.
    • parseBodyFragment

      public static Document parseBodyFragment(String bodyHtml, String baseUri)
      Parse a fragment of HTML into the body of a Document.
      Parameters:
      bodyHtml - fragment of HTML
      baseUri - base URI of document (i.e. original fetch location), for resolving relative URLs.
      Returns:
      Document, with empty head, and HTML parsed into body
    • unescapeEntities

      public static String unescapeEntities(String string, boolean inAttribute)

      Parameters:
      string - HTML escaped string

      Returns:
      an unescaped string
    • htmlParser

      public static Parser htmlParser()
      Create a new HTML parser. This parser treats input as HTML5, and enforces the creation of a normalised document, based on a knowledge of the semantics of the incoming tags.
      Returns:
      a new HTML parser.
    • xmlParser

      public static Parser xmlParser()
      Create a new XML parser. This parser assumes no knowledge of the incoming tags and does not treat it as HTML, rather creates a simple tree directly from the input.
      Returns:
      a new simple XML parser.
