You haven't supplied enough context to help you. Your fragment of a template is
fine so far as we can see it, so the problem must be coming from a larger
context that contains it.
Generally speaking, variables are one of the most confusing aspects of XSLT to
people accustomed to standard, imperative programming languages. Assuming that
the <xsl:choose> appears in a context that is repeated (inside a <xsl:for-each>
construct or inside a template that is called repeatedly), you could simplify
your code like this:
<xsl:variable name="status-color">
<xsl:when test="status='undelivered'">#ff0000</xsl:when>
<xsl:when test="status='inprogress'">#33cc33</xsl:when>
<xsl:when test="status=delivered">#0033ff</xsl:when>
<xsl:when test="status='escalated'">#ffff33</xsl:when>
<xsl:otherwise>000000</xsl:otherwise>
</xsl:variable>
<span style="color:{$status-color}">
<xsl:value-of sect="status"/>
</span>
The reason that a repetition is important is that once a variable is bound to a
value in a context, it cannot be changed. Every repetition of a template or a
for-each is a new context. In effect, the variable is a new variable each time.
The value is not re-assigned, instead the variable is re-created.

Subject: [xsl] Problem setting variable in if statement
I am very new to xsl/xslt and have a basic problem. I am setting a style
sheet color based on a condition.
I'd like the color to be a variable value, like
<xsl:variable name="statColor" select="#33cc33">
and set this variable in the if/choose condtion.
Then recall it like
<span style="color:{$statColor}"><xsl:value-of select="status"></span>
I have it like this now, but want to simplfiy it:
<xsl:choose>
<xsl:when test="status='undelivered'"> <span
style="color:#ff0000"> <xsl:value-of select="status"/></span>
</xsl:when>
<xsl:when test="status='inprogress'"> <span style="color:#33cc33">
<xsl:value-of select="status"/></span> </xsl:when>
<xsl:when test="status='delivered'"> <span style="color:#0033ff">
<xsl:value-of select="status"/></span> </xsl:when>
<xsl:when test="status='escalated'"> <span style="color:#ffff33">
<xsl:value-of select="status"/></span> </xsl:when>
<xsl:otherwise> <span style="color:#000000"> <xsl:value-of
select="status"/></span></xsl:otherwise>
</xsl:choose>
I cant seem to get it to work.
