Resolved: XSL String test

Hopefully I'm asking this in the right place. I have the following code:

Code:

---


<xsl:if test="/products/product/bookingweb != ''">
    <a><xsl:attribute name="href">http://<xsl:value-of select="/products/product/bookingweb" disable-output-escaping="yes" /></xsl:attribute><xsl:attribute name="target">_blank</xsl:attribute>
  <img class="linklist-image">
  <xsl:attribute name="src">images\bookonline_image.gif</xsl:attribute>
  <xsl:attribute name="border">0</xsl:attribute>
  </img>
  </a><br />
</xsl:if>

---

Rather than putting the html at the beginning of the booking web string automatically, I want to check whether the first 7 letters are http://. Now I don't know xsl very well at all, but its for this project in work. Can anybody help as to how I do this?


Thanks very much

I've sorted it. Incase anyone cares...

Code:

---


<xsl:choose>
                                       
<xsl:when test="starts-with /products/product/bookingweb,'http://')">
                                       
</xsl:when>
<xsl:otherwise>
http://
</xsl:otherwise>
</xsl:choose>
