Detailed documentation

addContent(content)

Appends the given node to the end of the document. The content argument can be a Content object or any node object that corresponds to a type listed in ContentType. Note, however, that a document can only have one child Element node, which is implicitly the root Element node.

Parameters

NameTypeDescription
contentContentthe node to append

Return

Document — the document, for chaining


addContent(index, content)

Inserts the given node at the given index among all nodes that are immediate children of the document. The content argument can be a Content object or any node object that corresponds to a type listed in ContentType. Note, however, that a document can only have one child Element node, which is implicitly the root Element node.

Parameters

NameTypeDescription
indexIntegerthe index at which to insert the node among all nodes that are immediate children of the document
contentContentthe node to insert

Return

Document — the document, for chaining


cloneContent()

Creates unattached copies of all nodes that are immediate children of the document.

Return

Content[] — an array of unattached copies of all nodes that are immediate children of the document


detachRootElement()

Detaches and returns the document's root Element node. If the document does not have a root Element node, this method returns null.

Return

Element — the detached Element node, or null if the document does not have a root Element node


getAllContent()

Gets all nodes that are immediate children of the document.

Return

Content[] — an array of all nodes that are immediate children of the document


getContent(index)

Gets the node at the given index among all nodes that are immediate children of the document. If there is no node at the given index, this method returns null.

Parameters

NameTypeDescription
indexIntegerthe index for the node among all nodes that are immediate children of the document

Return

Content — the node, or null if there is no node at the given index


getContentSize()

Gets the number of nodes that are immediate children of the document.

Return

Integer — the number of nodes that are immediate children of the document


getDescendants()

Gets all nodes that are direct or indirect children of the document, in the order they appear in the document.

Return

Content[] — an array of all nodes that are direct or indirect children of the document


getDocType()

Gets the document's DocType declaration. If the document does not have a DocumentType node, this method returns null.

Return

DocType — the DocumentType node, or null if the document does not have a DocumentType node


getRootElement()

Gets the document's root Element node. If the document does not have a root Element node, this method returns null.

Return

Element — the root Element node, or null if the document does not have a root Element node


hasRootElement()

Determines whether the document has a root Element node.

Return

Booleantrue if the document has a root Element node; false if not


removeContent()

Removes all nodes that are immediate children of the document.

Return

Content[] — an array of all nodes that were immediate children of the document before they were removed


removeContent(content)

Removes the given node, if the node is an immediate child of the document. The content argument can be a Content object or any node object that corresponds to a type listed in ContentType.

Parameters

NameTypeDescription
contentContentthe node to remove

Return

Booleantrue if the node was an immediate child and was removed; false if not


removeContent(index)

Removes the node at the given index among all nodes that are immediate children of the document. If there is no node at the given index, this method returns null.

Parameters

NameTypeDescription
indexIntegerthe index for the node among all nodes that are immediate children of the document

Return

Content — the node that was removed, or null if there is no node at the given index


setDocType(docType)

Sets the document's DocType declaration. If the document already has a different DocType node, this method overwrites the old node. This method throws an exception if the document already contains the same DocType node that is being set.

Parameters

Return

Document — the document, for chaining


setRootElement(element)
