<font color="$use-color">Hello</font>
This should have been <font color="{$use-color}">Hello</font>
** Notice the curly braces **
<font color="$use-color">Hello</font>
will not get the value of the $use-color variable to the color attribute
of the font tag.It will instead make the value of the color attribute to be
"$use-color"

I have a simple question that Im trying to solve:
This is a FAQ
<xsl-if test="some condition">
<font color="red"> Hello 1</font>
</xsl-if>
<xsl-if test="some other condition">
<font color="blue"> Hello 1</font>
</xsl-if>
Now, is there a way to obtain the above criteria something like,
<xsl-if test="some condition">
$somevariable = "red";
</xsl-if>
<xsl-if test="some other condition">
$somevariable = "blue";
</xsl-if>
<font color=$somevariable> Hello 1</font>
I understand that I cannot use <xml:param> and <xml:variable> as they are
constants. Please let me know a solution to this trivial problem.
Put the conditional around the value assigned, not around the assignment:
<xsl:variable name="use-color">
<xsl:choose>
<xsl:when test="some condition">red</xsl:when>
<xsl:when test="other condition">blue</xsl:when>
<xsl:otherwise>green</xsl:otherwise>
</xsl:choose>
</xsl:variable>
...
<font color="$use-color">Hello</font>
Some caveats when testing result-tree-fragment variables, they always test
true() until you cast them to the data type that you need.
I hope this helps.
