  • Constructor Details

    • DataNode

      public DataNode​(String data)
      Create a new DataNode.
      Parameters:
      data - data contents

  • Method Details

    • nodeName

      public String nodeName()
      Description copied from class: Node
      Get the node name of this node. Use for debugging purposes and not logic switching (for that, use instanceof).
      Specified by:
      nodeName in class Node
      Returns:
      node name

    • getWholeData

      public String getWholeData()
      Get the data contents of this node. Will be unescaped and with original new lines, space etc.
      Returns:
      data

    • setWholeData

      public DataNode setWholeData​(String data)
      Set the data contents of this node.
      Parameters:
      data - unencoded data
      Returns:
      this node, for chaining

    • toString

      public String toString()
      Description copied from class: Node
      Gets this node's outer HTML.
      Overrides:
      toString in class Node
      Returns:
      outer HTML.
      See Also:
      Node.outerHtml()

    • clone

      public DataNode clone()
      Description copied from class: Node
      Create a stand-alone, deep copy of this node, and all of its children. The cloned node will have no siblings or parent node. As a stand-alone object, any changes made to the clone or any of its children will not impact the original node.

      The cloned node may be adopted into another Document or node structure using Element.appendChild(Node).

      Overrides:
      clone in class Node
      Returns:
      a stand-alone cloned node, including clones of any children
      See Also:
      Node.shallowClone()

    • createFromEncoded

      @Deprecated public static DataNode createFromEncoded​(String encodedData, String baseUri)
      Deprecated.
      Unused, and will be removed in 1.15.1.
      Create a new DataNode from HTML encoded data.
      Parameters:
      encodedData - encoded data
      baseUri - base URI
      Returns:
      new DataNode

    • hasAttributes

      protected final boolean hasAttributes()
      Description copied from class: Node
      Check if this Node has an actual Attributes object.
      Specified by:
      hasAttributes in class Node

    • attributes

      public final Attributes attributes()
      Description copied from class: Node
      Get all of the element's attributes.
      Specified by:
      attributes in class Node
      Returns:
      attributes (which implements iterable, in same order as presented in original HTML).

    • attr

      public String attr​(String key)
      Description copied from class: Node
      Get an attribute's value by its key. Case insensitive

      To get an absolute URL from an attribute that may be a relative URL, prefix the key with abs, which is a shortcut to the Node.absUrl(java.lang.String) method.

      E.g.:
      String url = a.attr("abs:href");
      Overrides:
      attr in class Node
      Parameters:
      key - The attribute key.
      Returns:
      The attribute, or empty string if not present (to avoid nulls).
      See Also:
      Node.attributes(), Node.hasAttr(String), Node.absUrl(String)

    • attr

      public Node attr​(String key, String value)
      Description copied from class: Node
      Set an attribute (key=value). If the attribute already exists, it is replaced. The attribute key comparison is case insensitive. The key will be set with case sensitivity as set in the parser settings.
      Overrides:
      attr in class Node
      Parameters:
      key - The attribute key.
      value - The attribute value.
      Returns:
      this (for chaining)

    • hasAttr

      public boolean hasAttr​(String key)
      Description copied from class: Node
      Test if this Node has an attribute. Case insensitive.
      Overrides:
      hasAttr in class Node
      Parameters:
      key - The attribute key to check.
      Returns:
      true if the attribute exists, false if not.

    • removeAttr

      public Node removeAttr​(String key)
      Description copied from class: Node
      Remove an attribute from this node.
      Overrides:
      removeAttr in class Node
      Parameters:
      key - The attribute to remove.
      Returns:
      this (for chaining)

    • absUrl

      public String absUrl​(String key)
      Description copied from class: Node
      Get an absolute URL from a URL attribute that may be relative (such as an <a href> or <img src>).

      E.g.: String absUrl = linkEl.absUrl("href");

      If the attribute value is already absolute (i.e. it starts with a protocol, like http:// or https:// etc), and it successfully parses as a URL, the attribute is returned directly. Otherwise, it is treated as a URL relative to the element's Node.baseUri(), and made absolute using that.

      As an alternate, you can use the Node.attr(java.lang.String) method with the abs: prefix, e.g.: String absUrl = linkEl.attr("abs:href");

      Overrides:
      absUrl in class Node
      Parameters:
      key - The attribute key
      Returns:
      An absolute URL if one could be made, or an empty string (not null) if the attribute was missing or could not be made successfully into a URL.
      See Also:
      Node.attr(java.lang.String), URL(java.net.URL, String)

    • baseUri

      public String baseUri()
      Description copied from class: Node
      Get the base URI that applies to this node. Will return an empty string if not defined. Used to make relative links absolute.
      Specified by:
      baseUri in class Node
      Returns:
      base URI
      See Also:
      Node.absUrl(java.lang.String)

    • doSetBaseUri

      protected void doSetBaseUri​(String baseUri)
      Description copied from class: Node
      Set the baseUri for just this node (not its descendants), if this Node tracks base URIs.
      Specified by:
      doSetBaseUri in class Node
      Parameters:
      baseUri - new URI

    • childNodeSize

      public int childNodeSize()
