XSLT nested conditionals - how to do this - xslt

Question

I'm quite new to xslt
I have the following xslt snippet (pseudo'ed for clarity):
<xsl:for-each select="fields/field">
<xsl:if test="field=someThing">
<div>
<!--some content output-->
<!--here by doing-->
<!--some complex stuff-->
</div>
</xsl:if>
</xsl:for-each>
But based on value of field from loop, I optionally want to do some other stuff before the closing div.
So (armed with shiny new xsl book) I thought I could do something like this:
<xsl:for-each select="fields/field">
<xsl:if test="field=someThing">
<div>
<!--some content output-->
<!--here by doing-->
<!--some complex stuff-->
<xsl:choose>
<xsl:when test="field=someThingSpecific">
<div>
<!--process some additional-->
<!--stuff here-->
</div>
<!--then close div-->
</div>
</xsl:when>
<xsl:otherwise>
<!--nothing to do here-->
<!--just close the div-->
</div>
</xsl:otherwise>
</xsl:choose>
</xsl:if>
</xsl:for-each>
But it blows up.
Apparently because the closing div has moved into the conditional xsl:choose block
So 2 questions really:
why doesnt it work as is?
how can I achieve my objective?

It's blowing up because your XSLT isn't well-formed. When you open the first div outside of the xsl:choose, you have to close it outside the xsl:choose.
Also, if you don't need to do anything in your xsl:otherwise, just do another xsl:if:
<xsl:for-each select="fields/field">
<xsl:if test="field=someThing">
<div>
<!--some content output-->
<!--here by doing-->
<!--some complex stuff-->
<xsl:if test="field=someThingSpecific">
<div>
<!--process some additional-->
<!--stuff here-->
</div>
</xsl:if>
<!--then close div-->
</div>
</xsl:if>
</xsl:for-each>
