Truncate text with XSLT

Here is an XML fragment:

<stylist>
 <photo>thumb_image1.jpg</photo>
</stylist>


I need to be able to truncate the "thumb_" from the beginning of the string and append the rest of the string to an href.
as seen below:

<xsl:variable name="trimFileName">
    <xsl:value-of select="translate(photo,'thumb_','')" />
</xsl:variable>
                              
<a border="0" href="{$trimFileName}" target="_blank"><img src="{photo}" /></a>

The problem is that the translate function replaces any and all occurrences of the individual characters "t h u m b _".

Is there a function that allows me to just truncate a certain number of characters off of the string.  I have researched and there are (oddly enough) no trim functions.

Any suggestions appreciated.

there are three substring functions:

substring(string, startpos, [length])
substring-after(string1, string2)
substring-before(string1, string2)

<xsl:variable name="trimFileName">
    <xsl:value-of select="substring-after(photo, 'thumb_')" />
</xsl:variable>

will give you the string after thumb_

dfiala13,

I knew it was an easy fix!  I had seen plenty of examples of substring-before and after, but no documentation showing what they did.

Thank you very much! Exactly what i needed.  Thanks for the resource as well!
