Use this code as a working example -- of course you need to learn at least the basics of XSLT:
<xsl:stylesheet version="1.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output omit-xml-declaration="yes" indent="yes"/>
<xsl:variable name="vLink" select="'http://www.google.com'"/>
<xsl:template match="/">
<xsl:choose>
<xsl:when test="$vLink = 'http://www.google.com'">
It is the Google link...
</xsl:when>
<xsl:otherwise>
It is not (exactly) the Google link...
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
when this transformation is applied on any XML document (not used), the wanted result is produced:
It is the Google link...
One can also use a global <xsl:param>. This can be set externally by the invoker of the transformation.

Answer 2

Match against the content straight forward, and declare the URL as a variable.

Answer 3

If you need it more globally try this:
...
<xsl:apply-templates select="a" />
...
<xsl:template match="a">
Just a link
</xsl:template>
<xsl:template match="a[starts-with(#href, 'http://google.com/') or starts-with(#href, 'http://www.google.com/')]">
Link to google.com
</xsl:template>

It's possible to some extent, but there is no if-else construct in XSL. Here's a version I tested that you might be able to adapt to your needs. The input I used was:
<?xml-stylesheet type="text/xsl" href="test.xsl"?>
<xml>
<LinkValue>http://www.google.com/</LinkValue>
</xml>
The XSL that showing "Do something 1" if LinkValue was the string above or "Do something 2" if I modified it was:
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:template match="/">
<xsl:variable name="LinkValue" select="//LinkValue"/>
<xsl:element name="a">
<xsl:attribute name="href"><xsl:value-of select="$LinkValue"/></xsl:attribute>
<xsl:if test="$LinkValue = 'http://www.google.com/'">
Do something 1
</xsl:if>
<xsl:if test="$LinkValue != 'http://www.google.com/'">
Do something 2
</xsl:if>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
Hopefully you can use these samples to figure out exactly what you need to implement for your scenario.
