    • namespaceAware

      public boolean namespaceAware()
      Returns if this W3C DOM is namespace aware. By default, this will be true, but is disabled for simplicity when using XPath selectors in Element.selectXpath(String).
      Returns:
      the current namespace aware setting.

    • namespaceAware

      public W3CDom namespaceAware(boolean namespaceAware)
      Update the namespace aware setting. This impacts the factory that is used to create W3C nodes from jsoup nodes.

      For HTML documents, controls if the document will be in the default http://www.w3.org/1999/xhtml namespace if otherwise unset.

      .
      Parameters:
      namespaceAware - the updated setting
      Returns:
      this W3CDom, for chaining.

    • convert

      public static Document convert(Document in)

      W3C Document

    • asString

      public static String asString(Document doc, @Nullable Map<String,String> properties)
      Serialize a W3C document to a String. Provide Properties to define output settings including if HTML or XML. If you don't provide the properties (null), the output will be auto-detected based on the content of the document.
      Parameters:
      doc - Document
      properties - (optional/nullable) the output properties to use. See Transformer.setOutputProperties(Properties) and OutputKeys
      Returns:
      Document as string

    • OutputHtml

      public static HashMap<String,String> OutputHtml()
      Canned default for HTML output.

    • OutputXml

      public static HashMap<String,String> OutputXml()
      Canned default for XML output.

    • fromJsoup

      public Document fromJsoup(Document in)
      Convert a jsoup Document to a W3C Document. The created nodes will link back to the original jsoup nodes in the user property SourceProperty (but after conversion, changes on one side will not flow to the other).
      Parameters:
      in - jsoup doc
      Returns:
      a W3C DOM Document representing the jsoup Document or Element contents.

    • fromJsoup

      public Document fromJsoup(Element in)
      Convert a jsoup DOM to a W3C Document. The created nodes will link back to the original jsoup nodes in the user property SourceProperty (but after conversion, changes on one side will not flow to the other). The input Element is used as a context node, but the whole surrounding jsoup Document is converted. (If you just want a subtree converted, use convert(org.jsoup.nodes.Element, Document).)
      Parameters:
      in - jsoup element or doc
      Returns:
      a W3C DOM Document representing the jsoup Document or Element contents.

      Parameters:
      nodeList - the W3C nodes to get the original jsoup nodes from
      nodeType - the jsoup node type to retrieve (e.g. Element, DataNode, etc)
