When building an XSLT solution that uses Internet Explorer, you might want to use data islands as a convenient way to access XML data from an HTML page. Because XSLT is itself an XML grammar, data islands can be used to load style sheets as well. The simple-islands.htm example uses two data islands to load both the source XML data and the XSLT style sheet. The transformNode
method is used on these two data islands to generate HTML code that can then be inserted into the page.
When the simple-islands.htm page, including the data islands, is completely loaded, the onload
event fires and the transformNode
method is executed on the XML source data. The result of this call is XML text, which in this example is well-formed HTML text. You can feed this text directly into the <xslTarget>
element as in xslTarget.innerHTML = source.transformNode(style.XMLDocument)
The object returned from a data island is a DHTML DOM object (in this case it is the DHTML object associated with the <XML>
element), not an XML DOM object. The style.XMLDocument
property ensures that a style
object is passed to the transformNode
method as an XML DOM object.
There is no need to write source.XMLDocument.transformNode(style.XMLDocument)
, because transformNode
is an XML DOM method, not a DHTML method. When an XML DOM method is called on a DHTML object corresponding to the XML data island element, the script engine automatically resolves it to the XML DOM Document node. In general, the XMLDocument
property is not required if another DOM property or method is being applied.
You can also write source.XMLDocument.transformNode(style.documentElement)
and apply the style sheet to the document element instead of the root. However, the style sheet must reflect this. For example, the document element must be handled by a rule other than the root template xsl:template match="/"
, which will not be invoked unless the style sheet is executed against the document root. It is recommended that you process your style sheets off the document root so that they will also work for directly browsing XML. For more information about the differences between the document root and the document element, see How the DOM Defines the Context for XPath Expressions.
