Constructor Detail

XmlDeclaration

public XmlDeclaration(java.lang.String name,
                      boolean isProcessingInstruction)

Create a new XML declaration

Parameters:

name - of declaration

isProcessingInstruction - is processing instruction

XmlDeclaration

public XmlDeclaration(java.lang.String name,
                      java.lang.String baseUri,
                      boolean isProcessingInstruction)

Deprecated.

Create a new XML declaration

Parameters:

name - of declaration

baseUri - Leaf Nodes don't have base URIs; they inherit from their ReactElement

isProcessingInstruction - is processing instruction

XmlDeclaration(String, boolean)

Method Detail

nodeName

public java.lang.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

name

public java.lang.String name()

Get the name of this declaration.

Returns:

name of this declaration.

getWholeDeclaration

public java.lang.String getWholeDeclaration()

Get the unencoded XML declaration.

Returns:

XML declaration

toString

public java.lang.String toString()

Overrides:

toString in class Node

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 java.lang.String attr(java.lang.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(java.lang.String key,
                 java.lang.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.

Overrides:

attr in class Node

Parameters:

key - The attribute key.

value - The attribute value.

Returns:

this (for chaining)

hasAttr

public boolean hasAttr(java.lang.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(java.lang.String key)

Description copied from class: Node

Remove an attribute from this element.

Overrides:

removeAttr in class Node

Parameters:

key - The attribute to remove.

Returns:

this (for chaining)

absUrl

public java.lang.String absUrl(java.lang.String key)

Description copied from class: Node

Get an absolute URL from a URL attribute that may be relative (i.e. 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.URL(java.net.URL, String)

baseUri

public java.lang.String baseUri()

Description copied from class: Node

Get the base URI of this node.

Specified by:

baseUri in class Node

Returns:

base URI

doSetBaseUri

protected void doSetBaseUri(java.lang.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.

ensureChildNodes

protected java.util.List<Node> ensureChildNodes()

Specified by:

ensureChildNodes in class Node
