Changing the background based on value in xml using xsl

[ml41782]

I have a solarr grid tie system. the power data is dumped in xml. using xsl I want to change the color of the field based on the data going positive ( power from the grid ) or negative ( solar is pushing power to the grid )

I have been trying diffferent things and it just doesn't work. What am I missing ?

[html] <table border="3">
<tr bgcolor="#9acd32">
<th bgcolor="#ffff55" aligh="center" colspan="4">Current System Status</th>
<th bgcolor="#cc9966" aligh="center" colspan="4" border="3">Solar Energy System Status</th>
</tr>
<tr bgcolor="#9acd32">
<th bgcolor="#ddea99" align="center">Neg=Solar Pos=REC</th>
<th bgcolor="#ddea99" align="center">Voltage</th>
<th bgcolor="#ddea99" align="center">Amps</th>
<th bgcolor="#ddea99" align="center">Consumption</th>
</tr>
<tr>
<xsl:if test="watts &lt; 0>
<td bgcolor="#00ff00"><xsl:value-of select="xmlpower/record/watts" /></td>
</xsl:if>
<xsl:if test="watts &gt; 0>
<td bgcolor="#ff0000"><xsl:value-of select="xmlpower/record/watts" /></td>
</xsl:if>
<td bgcolor="#ffff00"><xsl:value-of select="xmlpower/record/volts" /></td>
<td bgcolor="#ffff00"><xsl:value-of select="xmlpower/record/amps" /></td>
<td bgcolor="#ffff00"><xsl:value-of select="xmlpower/record/power" /></td>
</tr>

Welcome to TheScripts TSDN....

Try this way:
[html]<xsl:if test="number(watts) &lt; 0">[/html]

Don't forget to close the quotation-marks after 0 (they are missing in your sample).

in my opinion u should define a class and then make a method to change the background color, and then access that method through extention objects and then u can even change the color at run time and can use for large files, without even writing bgcolor='xxxx' properties every time.
