Constructor Detail

SgmlPage

public SgmlPage(WebResponse webResponse,
                WebWindow webWindow)

Creates an instance of SgmlPage.

Parameters:

webResponse - the web response that was used to create this page

webWindow - the window that this page is being loaded into

Method Detail

cleanUp

public void cleanUp()

Clean up this page. This method gets called by the web client when an other page is loaded in the window and you should probably never need to call it directly

Specified by:

cleanUp in interface Page

getWebResponse

public WebResponse getWebResponse()

Returns the web response that was originally used to create this page.

Specified by:

getWebResponse in interface Page

Returns:

the web response

getNodeName

public String getNodeName()

Gets the name for the current node.

Specified by:

getNodeName in interface Node

Returns:

the node name

getNodeType

public short getNodeType()

Gets the type of the current node.

Specified by:

getNodeType in interface Node

Returns:

the node type

getEnclosingWindow

public WebWindow getEnclosingWindow()

Returns the window that this page is sitting inside.

Specified by:

getEnclosingWindow in interface Page

Returns:

the enclosing frame or null if this page isn't inside a frame

setEnclosingWindow

public void setEnclosingWindow(WebWindow window)

Sets the window that contains this page.

Parameters:

window - the new frame or null if this page is being removed from a frame

getWebClient

public WebClient getWebClient()

Returns the WebClient that originally loaded this page.

Returns:

the WebClient that originally loaded this page

createDocumentFragment

public DomDocumentFragment createDocumentFragment()

Creates an empty DomDocumentFragment object.

Specified by:

createDocumentFragment in interface Document

Returns:

a newly created DomDocumentFragment

getDoctype

public final DocumentType getDoctype()

Returns the document type.

Specified by:

getDoctype in interface Document

Returns:

the document type

setDocumentType

protected void setDocumentType(DocumentType type)

Sets the document type.

Parameters:

type - the document type

getPage

public SgmlPage getPage()

Returns the page that contains this node.

Overrides:

getPage in class DomNode

Returns:

the page that contains this node

getCharset

public abstract Charset getCharset()

Returns the encoding.

Returns:

the encoding

getDocumentElement

public DomElement getDocumentElement()

Returns the document element.

Specified by:

getDocumentElement in interface Document

Returns:

the document element

clone

protected SgmlPage clone()

Creates a clone of this instance.

Overrides:

clone in class Object

Returns:

a clone of this instance

asXml

public String asXml()

Returns a string representation as XML document from this element and all it's children (recursively).
The charset used in the xml header is the current page encoding; but the result is still a string. You have to make sure to use the correct (in fact the same) encoding if you write this to a file.
This serializes the current state of the DomTree - this implies that the content of noscript tags usually serialized as string because the content is converted during parsing (if js was enabled at that time).

Overrides:

asXml in class DomNode

Returns:

the XML string

hasCaseSensitiveTagNames

public abstract boolean hasCaseSensitiveTagNames()

Returns true if this page has case-sensitive tag names, false otherwise. In general, XML has case-sensitive tag names, and HTML doesn't. This is especially important during XPath matching.

Returns:

true if this page has case-sensitive tag names, false otherwise

normalizeDocument

public void normalizeDocument()

The current implementation just DomNode.normalize()s the document element.

Specified by:

normalizeDocument in interface Document

getCanonicalXPath

public String getCanonicalXPath()

Returns the canonical XPath expression which identifies this node, for instance "/html/body/table[3]/tbody/tr[5]/td[2]/span/a[3]".

WARNING: This sort of automated XPath expression is often quite bad at identifying a node, as it is highly sensitive to changes in the DOM tree.

Overrides:

getCanonicalXPath in class DomNode

Returns:

the canonical XPath expression which identifies this node

See Also:

DomNode.getByXPath(String)

createAttribute

public DomAttr createAttribute(String name)

Specified by:

createAttribute in interface Document

getUrl

public URL getUrl()

Returns the URL of this page.

Specified by:

getUrl in interface Page

Returns:

the URL of this page

isHtmlPage

public boolean isHtmlPage()

Description copied from interface: Page

Returns true if this page is an HtmlPage.

Specified by:

isHtmlPage in interface Page

Returns:

true or false

getElementsByTagName

public DomNodeList<DomElement> getElementsByTagName(String tagName)

Specified by:

getElementsByTagName in interface Document

getElementsByTagNameNS

public DomNodeList<DomElement> getElementsByTagNameNS(String namespaceURI,
                                                      String localName)

Specified by:

getElementsByTagNameNS in interface Document

createCDATASection

public CDATASection createCDATASection(String data)

Specified by:

createCDATASection in interface Document

createTextNode

public Text createTextNode(String data)

Specified by:

createTextNode in interface Document

createComment

public Comment createComment(String data)

Specified by:

createComment in interface Document

                                          int whatToShow,
                                          org.w3c.dom.traversal.NodeFilter filter,
                                          boolean entityReferenceExpansion)
                                   throws DOMException

Create a new NodeIterator over the subtree rooted at the specified node.

Parameters:

root - The node which will be iterated together with its children. The NodeIterator is initially positioned just before this node. The whatToShow flags and the filter, if any, are not considered when setting this position. The root must not be null.

whatToShow - This flag specifies which node types may appear in the logical view of the tree presented by the NodeIterator. See the description of NodeFilter for the set of possible SHOW_ values.These flags can be combined using OR.

filter - The NodeFilter to be used with this NodeIterator, or null to indicate no filter.

entityReferenceExpansion - The value of this flag determines whether entity reference nodes are expanded.

Returns:

The newly created NodeIterator.

Throws:

DOMException - NOT_SUPPORTED_ERR: Raised if the specified root is null.
