      doctype System ID
    • 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
    • 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 element 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()
      Description copied from class: Node
      Get the number of child nodes that this node holds.

      the number of child nodes that this node holds.
    • empty

      public Node empty()
      Description copied from class: Node
      Delete all this node's children.
      Specified by:
      empty in class Node
      Returns:
      this node, for chaining
