The XSLT files that Solr has standard are pretty good and cover a wide variety of different transforms however they didnt give me exactly what I wanted. I use Nutch as a filesystem crawler and therefore wanted the XSLT transform to make all the ur'ls(uri's) to the crawled files to be hyperlinks, so that when I clicked on them it would either download that file or allow me to view it in my browser. I therefore decided that I would make my own XSLT file even though I had no previous experience using XSLT before so I have adapted the example.xsl file that comes standard with Solr and this is the final version:
<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet version='1.0'
xmlns:xsl='http://www.w3.org/1999/XSL/Transform'
>
<xsl:output media-type="text/html" encoding="UTF-8"/>
<xsl:variable name="title" select="concat('Solr search results (',response/result/@numFound,' documents)')"/>
<xsl:template match='/'>
<html>
<head>
<title><xsl:value-of select="$title"/></title>
<xsl:call-template name="css"/>
</head>
<body>
<h1><xsl:value-of select="$title"/></h1>
