xsl:when problem

I want to add a conditional hyperlink to my to a certain element 
<xsl:choose>
       <xsl:when test='tag ="blabla"'>
       	<a href="blabla.htm"><xsl:value-of select="tag" /></a>
       </xsl:when>
	<xsl:otherwise>
		<xsl:value-of select="tag" />
	</xsl:otherwise>
</xsl:choose>

This is part of the xsl document

With in the corresponding xml document

<tag>blabla</tag>

This works if the tag-value pair is exactly the above BUT

if, for readability's sake, I try to write the tag-value pair like this
		<tag>
			blabla
		</tag>
then it doesn't match the test criterium

Is there some kind of solution for this (I was thinking about regular
expressions).
