[xsl] check for existance of an element in the xml

Subject: [xsl] check for existance of an element in the xml

HI all
I would to check for the existance of an element, and act upon it, rather than act everytime the element is matched. What i mean is I have xml that describes how a web page looks, and an xsl that transforms that to html and javascript.

For example, i may have this :

<page>
<groupbox x="10" y="10">
<text value="Blaa Blaa" x="10" y="10"/>
<input x="10" y="20" name="foo"/>
</groupbox>
<groupbox x="10" y="30">
<text value="Something Else" x="10" y="10"/>
<input x="10" y="20" name="bar"/>
</groupbox>
<input x="10" y="50" name="gle"/>
</page>

The issue is that at the moment i have some javascript that operates on the input fields, so I am including it everytime I produce a page, but I want to only include it iff the xml has at least one <input .../> element. This is of course simplified, the real xml and the html it produces is a lot more complicated, some of the html pages produced are getting fairly large :)
The xsl root match is where i am including all the various javascript files. Here is a simplified version of my xslt, for those who dont do html :

<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform";>
<xsl:output method="html"/>

<xsl:template match="/">
<html>
<head>
<script language="JavaScript" src="Shared/Javascript/validate.js"></script>
</head>
<body> <xsl:apply-templates/>
</body>
</html>
</xsl:template>
<xsl:template match="input">
<!-- input field code goes here -->
</xsl:template>
.
.
.
</xsl:stylesheet>

I only want that <script language="JavaScript" src="Shared/Javascript/validate.js"></script> part to appear once in the resulting html iff the xml i am processing has at least one <input..../> element. I figure i can parse the xml twice, but i cant work out how i would only match unique elements the first time :) What sort of thing should i be googleing for in order to solve this problem, it seems like the sort of thing people would want to do....
