I have a xml file that contains some data. I use a xsl file to display the data in the form of a table.
Please check the xml code and xsl code and the screenshot

I have a drop-down box that displays the Conference Names from the first table. What i want is, when i select a conference name, data relevant to it should be displayed in the second table. The data that is not relevant to a particular conference name should not be displayed. Right now, I am displaying all the data from the xml file.
How do i set a condition in xsl to display data based on my selection in the drop-down ?
Generally:
You need to provide as a global (externally specified) parameter to the transformation a value that uniquely identifies the selected conference.
The value of this parameter is set by the code (JS in this case) that initiates the transformation — you need to read the documentation to understand how exactly this must be done.
Then in your XSLT code, from the value of this parameter, identify the desired
Conferenceelement and apply templates only to this element.Unfortunately, in the provided XML document more than one conference have both the same ID and the same Name…
