Subject: Re: [xsl] How can i access a JSP function in XSL? From: Suman.Sathyanarayan@xxxxxxxxxxxx Date: Wed, 1 May 2002 15:31:47 +0530 |
Hi Peter, Thanks for the help. I had a better solution. My XML is also generated using a JSP. i.e JSP outputs an XML and another JSP ouputs an XSL But the way i paint my elements / attribute/values for the XML in the JSP are purely Java. So i put in the function there itself in the **XML-JSP**, so i process the data , before generating the XML-JSP itself and give it to the XSL to display. i display an HTML finally. But i think the cocoon site's really good, And of course these suggesstion's will be of great help later on.

You can't use a value returned from the XSLT while the JSP is running, because the JSP *outputs* the XSLT -- which means the XSLT is executed after the JSP. What you have here will essentially be the same as: <% getTelephoneNumber("\n <xsl:value-of select=\"value\"/> \n"); %> which is probably not what you want. You will have to do one of three things: * If you are making an HTML page, then you will have to do something like this in your XSLT: <input type="hidden" name="phone" value="{value}"/> which uses an Attribute Value Template that will output the phone number into the <input value="..."/>. You then have to put that into a <form> and make the user click "submit" to return the value to the server where you can do more processing -- pretty ugly. * Check out the Cocoon project (http://xml.apache.org/cocoon), and convert all of your .jsp files to .xsp. This is a totally new language, so converting won't be easy, but it *might* be able to do what you want (emphasis on *might*, since you still won't be able to use XSLT directly in the page) * Use your processor's extension mechanism to be able to access getPhoneNumber() in the XSLT, so you can do something like: <xsl:value-of select="xx:getPhoneNumber(value)"/> This is probably the best way to go, but it depends on a lot of other factors such as the processor, where getPhoneNumber is defined, and whether getPhoneNumber relies on non-static state that is innaccessible from where it is called by the extension. - -- Peter Davis -----BEGIN PGP SIGNATURE----- Version: GnuPG v1.0.6 (GNU/Linux) Comment: For info see http://www.gnupg.org iD8DBQE8z8MmNSZCJx7tYycRAjQaAJwPZ1PqA9/TCJO9tD5NMx3vbUXmjgCg2FBb dK5TjUQxzYXZRjHT1XhYhwU= =wB5K -----END PGP SIGNATURE----- XSL-List info and archive: http://www.mulberrytech.com/xsl/xsl-list -----------------------Disclaimer------------------------ The views of the author may not necessarily reflect those of the Company.
