xsl:attribute tag not working

This is driving me crazy ... Here is a fragement of xsl from an xsl style sheet.

<TR>
<TD align="center" width="82%" valign="middle">
<xsl:variable name="SortOrder" select="/Notifications/Sort/@Order"/>
<B><font color="#FFFFFF" face="arial">Sort by </font></B>
<SELECT id="select1" style="FONT-SIZE: x-small; WIDTH: 150px" name="sortby" onchange="javascript:newSort(value);">
<OPTION value="1">3 Month Reservations</OPTION>
<xsl:if test="$SortOrder[. = 1]">
<xsl:attribute name="SELECTED"></xsl:attribute>
</xsl:if>
<OPTION value="2">Property Name</OPTION>
<xsl:if test="$SortOrder[. = 2]">
<xsl:attribute name="SELECTED"></xsl:attribute>
</xsl:if>
<OPTION value="3">Property Id</OPTION>
<xsl:if test="$SortOrder[. = 3]">
<xsl:attribute name="SELECTED"></xsl:attribute>
</xsl:if>
</SELECT>
<xsl:if test="$SortOrder[. = 2]">
<xsl:text>TEST WAS PASSED</xsl:text>
</xsl:if>
</TD>
</TR>

All I want to do is to set the SELECTED attribute.

Here is the HTML I get:

<TR>
<TD align="center" width="82%" valign="middle"><B><font color="#FFFFFF" face="arial">Sort by </font></B><SELECT id="select1" style="FONT-SIZE: x-small; WIDTH: 150px" name="sortby" onchange="javascript:newSort(value);"><OPTION value="1">3 Month Reservations</OPTION>
<OPTION value="2">Property Name</OPTION>
<OPTION value="3">Property Id</OPTION></SELECT>TEST WAS PASSED</TD>
</TR>

Please note that the last text string indicates that I am picking up the desired node value and testing it properly. The only issue is that the SELECTED attribute is, never-the-less NOT set.

Can anyone give me a clue as to what might be going on?

Robad,

Although I don't think that this is your problem, you should give the selected attribute a value. In XHTML this should be the name of the attribute.

e.g.
<xsl:attribute name="selected">selected</xsl:attribute>

Apart from that I can't see any problem with the XSL code. I would however need to see the XML that you are tranforming. What does 'select="/Notifications/Sort/@Order"/' actually match? If this is not 1, 2 or 3, then you will not get the select attribute in the output.

You could also try:
<xsl:if test="number($SortOrder) = 2]">

>S'Plug<

As sparky said, give the attribute a value, and ensure that the xsl:output method is set to html. Then the tree flattener will produce the correct HTML.

I should clarify that the following (from my original question) is debugging code to make sure that the xsl:if test = is properly structured:
<xsl:if test="$SortOrder[. = 2]">
<xsl:text>TEST WAS PASSED</xsl:text>
</xsl:if>

When the source xml contains <Sort Order="2"/>, the html output contains

<OPTION value="3">Property Id</OPTION></SELECT>TEST WAS PASSED</TD>

This tells me that the problem is NOT with the if test. Also, I have already tried giving the SELECTED attribute a value along the lines of

<xsl:attribute name="SELECTED">SELECTED</xsl:attribute>

OR

<xsl:attribute name="SELECTED"><xsl:text></xsl:text></xsl:attribute>

Neither makes a difference. Further, I am using Microsoft XSL 4.0 which creates an attribute

SELECTED = ""

with no value assigned in a different style sheet.

Thanks much!

Sometimes I can't see for seeing with my own code.
