Re: [xsl] Selecting and printing certain nodes

You guy's are great! Thanks so much for the help. I went on David and
Wendell's suggestions, it simplified it quite a bit and it works exactly as
I want. This is great!

I have a couple more questions...sorry...

XML snipit:
<variable name="$startDate"/>

XSL snipit:
<xsl:template match="variable">
    <xsl:if test="@name"/>
        <xsl:value-of select="@name"/>
    </xsl:if>
</xsl:template>

This prints out '$startDate' when I really want it to print the value of the
xsl:param $startDate. Is there a way to do this in XSL?

So let me explain my situation with some examples:

XML input file:
<html>
<head><title>This is the title of the document</title></head>
<body>
<table border="1" cellpadding="0">
<tr><td colspan="2"><replace with="tag">title</replace></td></tr>
<tr><td colspan="2">&nbsp;</td></tr>
<foreach param="devices">
<tr>
<td>The device is <variable> Param is P1</td>
<td>The device is <variable> Param is P2</td>
</tr>
</foreach>
</body>
</html>

So the replace just replaces itself with the text of the title name, no
problem there I use the exslt dyn:evaluate function for that.
Next is the foreach. This works by the stylesheet opening the 'devices.xml'
file using the document function and reading out the /doc/items

<xsl:template match="foreach">
<xsl:param name="var"/>
<xsl:variable name="here" select="."/>
<xsl:for-each select="document(@param)/doc/item">
<div>
<xsl:apply-templates select="$here/node()">
<xsl:with-param name="var" select="."/>
</xsl:apply-templates>
</div>
</xsl:for-each>
</xsl:template>

<xsl:template match="variable">
<xsl:param name="var"/>
<xsl:value-of select="$var"/>
</xsl:template>

This all work great. Now my question is can you think of a way to handle
nested foreach statments?

<foreach param="devices">
<tr><td colspan="2"><variable/></td></tr>
<foreach param="parameters">
<tr><td><variable/></td></tr>
</foreach>
</foreach>

Do I need to pass a variable which is an array or something

Thanks

        Glenn
