Constructor Detail

DocumentType

public DocumentType(String name,
                    String publicId,
                    String systemId)

Create a new doctype element.

Parameters:

name - the doctype's name

publicId - the doctype's public ID

systemId - the doctype's system ID

Method Detail

setPubSysKey

public void setPubSysKey(String value)

name

public String name()

Get this doctype's name (when set, or empty string)

Returns:

doctype name

publicId

public String publicId()

Get this doctype's Public ID (when set, or empty string)

Returns:

doctype Public ID

systemId

public String systemId()

Get this doctype's System ID (when set, or empty string)

Returns:

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 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()

Description copied from class: Node

Get the number of child nodes that this node holds.

Specified by:

childNodeSize in class Node

Returns:

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

ensureChildNodes

protected List<Node> ensureChildNodes()

Specified by:

ensureChildNodes in class Node

doClone

protected org.jsoup.nodes.LeafNode doClone(Node parent)

Overrides:

doClone in class Node
