which is the same input tree to xsl as


<string>
	&lt;u&gt;Link containing a &amp; character&lt;/u&gt;
</string>

You didn't specify how you set the variable linkTextUnStripped
but unless it was defined via normalise-space() then
"4" is unlikely to be the right number, and starts-with is not going to
be true. As the fist four characters are
&#10;&#32;&#32;&#32;

The less than (&lt;) is the 10th character in the string, unless I mis
counted.

Why not use 


<xsl:when test="contains($linkTextUnStripped, '&lt;u&gt;')">
	<xsl:value-of select="
    substring-before(substring-after(, '&lt;u&gt;'), '&lt;/u&gt;') "/>
</xsl:when>
