This function translates using the streaming XPath APIs. It uses batching so that the transformation engine does not materialize the result of the transformation into memory. Therefore, it can handle arbitrarily large payloads of the order of gigabytes. However, it can only handle forward-only XSL constructs such as for-each. The targetType can be SDOM or ATTACHMENT.

Signature:

med:doStreamingTranslate('input','streaming xpath context','targetType','attachment element'?)

Arguments:

• input: The input data of the XPath function. This can be an SDOM or attachment element.

• streaming xpath context

• targetType: Determines how the XPath function translates the native data into XML.

• attachment element: The attachment for the returned XML. This parameter is optional.

Property IDs:

• namespace-uri: http://schemas.oracle.com/xpath/extension

• namespace-prefix: med

Example:

med.doStreamingTranslate($in.request/inp1:request/inp1:sourceAttachmentElement,$in.request/inp1:request/inp1:streamingcontext, 'ATTACHMENT', $in.request/inp1:request/inp1:targetAttachmentElement)
