      Overrides:
      attr in class Node
      Parameters:
      attributeKey - The attribute key.

      Returns:
      this element
    • attr

      public Element attr​(String attributeKey, boolean attributeValue)
      Set a boolean attribute value on this element. Setting to true sets the attribute value to "" and marks the attribute as boolean so no value is written out. Setting to false removes the attribute with the same key if it exists.

      E.g., the element <div data-package="jsoup" data-language="Java" class="group">... has the dataset package=jsoup, language=java.

      This map is a filtered view of the element's attribute map. Changes to one map (add, remove, update) are reflected in the other map.

      You can find elements that have data attributes using the [^data-] attribute key prefix selector.

      Returns:
      a map of key=value custom data attributes.
    • parent

      public final Element parent()
      Description copied from class: Node
      Gets this node's parent node.
      Overrides:

      Returns:
      parent node; or null if no parent.
    • parents

      public Elements parents()
      Get this element's parent and ancestors, up to the document root.
      Returns:
      this element's stack of parents, closest first.
    • child

      public Element child​(int index)
      Get a child element of this element, by its 0-based index number.

      Note that an element can have both mixed Nodes and Elements as children. This method inspects a filtered list of children that are elements, and the index is based on that filtered list.

      Parameters:
      index - the index number of the element to retrieve
      Returns:
      the child element, if it exists, otherwise throws an IndexOutOfBoundsException
      See Also:
      Node.childNode(int)
    • childrenSize

      public int childrenSize()
      Get the number of child nodes of this element that are elements.

      This method works on the same filtered list like child(int). Use Node.childNodes() and childNodeSize() to get the unfiltered Nodes (e.g. includes TextNodes etc.)

      Returns:
      the number of child nodes that are elements
      See Also:
      children(), child(int)
    • children

      public Elements children()
      Get this element's child elements.

      This is effectively a filter on Node.childNodes() to get Element nodes.

      Returns:
      child elements. If this element has no children, returns an empty list.
      See Also:
      Node.childNodes()
    • textNodes

      public List<TextNode> textNodes()
      Get this element's child text nodes. The list is unmodifiable but the text nodes may be manipulated.

      This is effectively a filter on Node.childNodes() to get Text nodes.

      Returns:
      child text nodes. If this element has no text nodes, returns an empty list.

      For example, with the input HTML: <p>One <span>Two</span> Three <br> Four</p> with the p element selected:
      • p.text() = "One Two Three Four"
      • p.ownText() = "One Three Four"
      • p.children() = Elements[<span>, <br>]
      • p.childNodes() = List<Node>["One ", <span>, " Three ", <br>, " Four"]
      • p.textNodes() = List<TextNode>["One ", " Three ", " Four"]
    • dataNodes

      public List<DataNode> dataNodes()
      Get this element's child data nodes. The list is unmodifiable but the data nodes may be manipulated.

      This is effectively a filter on Node.childNodes() to get Data nodes.

      Returns:
      child data nodes. If this element has no data nodes, returns an empty list.
      See Also:
      data()
    • select

      public Elements select​(String cssQuery)
      Find elements that match the Selector CSS query, with this element as the starting context. Matched elements may include this element, or any of its children.

      This method is generally more powerful to use than the DOM-type getElementBy* methods, because multiple filters can be combined, e.g.:

      • el.select("a[href]") - finds links (a tags with href attributes)
      • el.select("a[href*=example.com]") - finds links pointing to example.com (loosely)

      See the query syntax documentation in Selector.

      Also known as querySelectorAll() in the Web DOM.

      Parameters:
      cssQuery - a Selector CSS-like query
      Returns:
      an Elements list containing elements that match the query (empty if none match)
      Throws:
      Selector.SelectorParseException - (unchecked) on an invalid CSS query.
      See Also:
      selector query syntax, QueryParser.parse(String)
    • select

      public Elements select​(Evaluator evaluator)
      Find elements that match the supplied Evaluator. This has the same functionality as select(String), but may be useful if you are running the same query many times (on many documents) and want to save the overhead of repeatedly parsing the CSS query.
      Parameters:
      evaluator - an element evaluator
      Returns:
      an Elements list containing elements that match the query (empty if none match)
    • selectFirst

      public Element selectFirst​(String cssQuery)
      Find the first Element that matches the Selector CSS query, with this element as the starting context.

      This is effectively the same as calling element.select(query).first(), but is more efficient as query execution stops on the first hit.

      Also known as querySelector() in the Web DOM.

      Parameters:
      cssQuery - cssQuery a Selector CSS-like query
      Returns:
      the first matching element, or null if there is no match.
    • selectFirst

      public Element selectFirst​(Evaluator evaluator)
      Finds the first Element that matches the supplied Evaluator, with this element as the starting context, or null if none match.
      Parameters:
      evaluator - an element evaluator
      Returns:
      the first matching element (walking down the tree, starting from this element), or null if none matchn.
    • is

      public boolean is​(String cssQuery)
      Checks if this element matches the given Selector CSS query. Also knows as matches() in the Web DOM.
      Parameters:

      Returns:
      if this element matches the query
    • is

      public boolean is​(Evaluator evaluator)

      if this element matches
    • closest

      public Element closest​(String cssQuery)
