Interface DOMLookup

All Known Implementing Classes:

DOMLookupByRobustXPath, DOMLookupByUniqueXPath, DOMLookupDocumentPosition

public interface DOMLookup

These interface specifies classes that compensate for an issue (observed in Mozilla), where DOM references perpetuate after new pages are loaded and the old page is revisited by invoking browser.back(). Prepare references with getNodeReferences(nodes). Retrieve new nodes via a call to getRenderedNode(staleNode,newDocument).

Method Detail

getNodeReferences

ArrayList<NodeReference> getNodeReferences(IOXPathNodeList nodes)
                                    throws OXPathException

Creates a list of references to nodes so that they can be found in a new document. Remember to handle the notional root if passed it!

Parameters:

nodes - the list of OXPathNodes

Returns:

references to these nodes retrievable in a new document

Throws:

OXPathException - in case of browser error (will carry the throwable cause)

getRenderedNodes

IOXPathNodeList getRenderedNodes(List<NodeReference> refs,
                                 DOMDocument document)
                          throws OXPathException

Throws:

OXPathException

getWebBrowser

WebBrowser getWebBrowser()

getNodeReference

NodeReference getNodeReference(OXPathContextNode context)
