DataNode
Create a new DataNode.- Parameters:
data
- data contents
-
-
Method Details
-
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). -
getWholeData
Get the data contents of this node. Will be unescaped and with original new lines, space etc.- Returns:
- data
-
setWholeData
Set the data contents of this node.- Parameters:
data
- unencoded data- Returns:
- this node, for chaining
-
toString
Description copied from class:Node
Gets this node's outer HTML. -
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)
. -
hasAttributes
protected final boolean hasAttributes()Description copied from class:Node
Check if this Node has an actual Attributes object.- Specified by:
hasAttributes
in classNode
-
attributes
Description copied from class:Node
Get each of the element's attributes.- Specified by:
attributes
in classNode
- Returns:
- attributes (which implements iterable, in same order as presented in original HTML).
-
attr
Description copied from class:Node
Get an attribute's value by its key. Case insensitiveTo get an absolute URL from an attribute that may be a relative URL, prefix the key with
E.g.:abs
, which is a shortcut to theNode.absUrl(java.lang.String)
method.String url = a.attr("abs:href");
-
attr
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. -
hasAttr
Description copied from class:Node
Test if this Node has an attribute. Case insensitive. -
removeAttr
Description copied from class:Node
Remove an attribute from this node.- Overrides:
removeAttr
in classNode
- Parameters:
key
- The attribute to remove.- Returns:
- this (for chaining)
-
absUrl
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://
orhttps://
etc), and it successfully parses as a URL, the attribute is returned directly. Otherwise, it is treated as a URL relative to the element'sNode.baseUri()
, and made absolute using that.As an alternate, you can use the
Node.attr(java.lang.String)
method with theabs:
prefix, e.g.:String absUrl = linkEl.attr("abs:href");
-
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. -
doSetBaseUri
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 classNode
- Parameters:
baseUri
- new URI
-
childNodeSize
public int childNodeSize()Description copied from class:Node
Get the number of child nodes that this node holds.- Specified by:
childNodeSize
in classNode
- Returns:
- the number of child nodes that this node holds.
-
empty
Description copied from class:Node
Delete all this node's children. -
ensureChildNodes
- Specified by:
ensureChildNodes
in classNode
-
doClone
