Use Java to process the XSLT stylesheet

Question

Background:-
I used Java to design a very simple Interface, which was composed of two components, one is an editable comboBox, the other is a button. What I want to achieve is selecting the value in the combobox and clicking the button, then it will achieve the relevant transformation process against the value selected from the comboBox.
Implementation:-
The transformation process is to extracting a set of information about a certain bird from an XML document, which contains many birds' information, to form a new XML document of one bird. The bird that I want to transform is listed in the comboBox and can be selected there. I use the Java to control the transformation process. My design is: I use Java programme to read the selected comboBox's value (bird name) and pass this value to the XSLT stylesheet, which is used to transform the XML document to a new XML document. What I have implemented: The Java programme has successfully controlled the transformation process, but I have defined in the XSLT stylesheet the bird name in advance. So the transformation is limited.
What I want:-
What I want is the transformation process will be carried out based on the value (bird name) read from the comboBox on the interface. And I hope to use Java to achieve this design!
XSLT stylesheet code:-
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:fo="http://www.w3.org/1999/XSL/Format">
<xsl:template match="node()">
     <xsl:apply-templates/>
</xsl:template>
<xsl:template match="class[own-slots/own-slot/entry/value = 'Barn_swallow']">
     <xsl:copy-of select="."/>
</xsl:template>
</xsl:stylesheet> I am very appreciated if you can provide me some helps kindly!
Thanks a lot! Waiting for your nice suggestions!

Answer 1

I mean, you can find the bird name(Barn_swallow) in my
attached XSLT stylesheet code. This name was actually
defined in advance. What I want to perform now is to
use the Java program to get the bird name from the
comboBox (you have gave out the method) and pass it to
the XSLT(actually needed to implement by Java), then
continue to use the Java programe to achieve the
transformation process (this step, I think, has been
achieved.) Obviously, how to perform the second step
"pass it to the XSLT" is the current task!What can you do already? Can you get a Transformer object from a TransformerFactory? If so, then simply call its setParameter("bird", "Barn Swallow") method. You'll have to declare a top-level xsl:param element whose name is "bird" in your XSL transformation, which you can then use as if it were a variable.
