SimpleXPathAPI Input

I'm just getting started with Xalan. I've built the sample programs and am experimenting with them to get started. In the SimpleXPathAPI sample, is there a way to use a memory buffer rather than a file as my input source?

Thanks,

Steve

If you're using Xalan-C, you can use C++ IOStreams.  See the
StreamTransform sample for more information about how you can create an
XSLTInputSource with a std::istream instance.

You could also use the Xerces class MemBufInputSource.

Assuming you mean a buffer that containx the XML text to be searched, and 
that you're working with Xalan-J: create a reader that pulls data from 
your buffer, then wrap a StreamSource around that. The sample programs 
that come with Xalan-J demonstrate doiing this for a stylesheet; the same 
solution should work for the XPath API.

(Alternatively, of course, you can parse the text into a DOM tree or SAX 
stream yourself, then pass us a DOMSource or SAXSource.)
