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

initialize

public void initialize()
                throws IOException

Initialize this page. This method gets called when a new page is loaded and you should probably never need to call it directly.

Specified by:

initialize in interface Page

Throws:

IOException - if an IO problem occurs

getNodeName

public String getNodeName()

Gets the name for the current node.

Specified by:

getNodeName in interface Node

Specified by:

getNodeName in class DomNode

Returns:

the node name

getNodeType

public short getNodeType()

Gets the type of the current node.

Specified by:

getNodeType in interface Node

Specified by:

getNodeType in class DomNode

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

createDomDocumentFragment

public DomDocumentFragment createDomDocumentFragment()

Creates an empty DomDocumentFragment object.

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(DomDocumentType 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

createElement

public abstract Element createElement(String tagName)

Creates an element, the type of which depends on the specified tag name.

Specified by:

createElement in interface Document

Parameters:

tagName - the tag name which determines the type of element to be created

Returns:

an element, the type of which depends on the specified tag name

createElementNS

public abstract Element createElementNS(String namespaceURI,
                      String qualifiedName)

Create a new Element with the given namespace and qualified name.

Specified by:

createElementNS in interface Document

Parameters:

namespaceURI - the URI that identifies an XML namespace

qualifiedName - the qualified name of the element type to instantiate

Returns:

the new element

getPageEncoding

public abstract String getPageEncoding()

Returns the page encoding.

Returns:

the page 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 of the XML document from this element and all it's children (recursively). The charset used is the current page encoding.

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

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:
