Efficient XSLT to Render Hyperlink

I have some XSLT which appears to do what I need it to (listed in the source snippet box below). What I want to know, is this the simplest way of doing this?

The XSLT renders the hyperlink URL next to the link text (only when printed).
Visit EE (www.experts-exchange.com)

The URL should only be rendered when:
   - The link text is not a URL itself.
            <hyperlink href="www.experts-exchange.com">www.experts-exchange.com</hyperlink>
   - The link text is blank (because the URL is rendered instead of text).
            <hyperlink href="www.experts-exchange.com"></hyperlink>
   - The URL refers to a page, website, or file. I don't want anything like 'javascript:addTotals' to be rendered!!
            <hyperlink href="javascript:addTotals();">Calculate Totals</hyperlink>
<xsl:template match="hyperlink" mode="content">
	<xsl:variable name="innerText" select="child::node()" />
	<a>
		<xsl:attribute name="href">
			<xsl:choose>
				<xsl:when test="string-length(@href)>0">
					<xsl:value-of select="@href" />
				</xsl:when>
				<xsl:otherwise>
					<xsl:text>#</xsl:text>
				</xsl:otherwise>
			</xsl:choose>
		</xsl:attribute>
		<xsl:choose>
			<xsl:when test="string-length($innerText)>0">
				<xsl:call-template name="render-html-content" />
			</xsl:when>
			<xsl:otherwise>
				<xsl:value-of select="@href" />
			</xsl:otherwise>
		</xsl:choose>
	</a>
	<xsl:if test="string-length($innerText)>0 and not(contains($innerText,'www.') or contains($innerText,'tp://') or starts-with(@url,'javascript:'))">
		<span class="PrintOnly">
			<xsl:text> (</xsl:text>
			<span style="color: green">
				<xsl:value-of select="@href" />
			</span>
			<xsl:text>)</xsl:text>
		</span>
	</xsl:if>
</xsl:template>

Excellent, thanks for checking that for me. Some pages can have a lot of links, and I wanted to make sure that the XSLT was as efficient as possible so as not to kill my server when this thing goes live.
