XSLT and `foreach`

Question

I have the following line of xml that I'm trying transform using XSLT but I'm having trouble. The line is

<app>
<lem>text</lem>
<rdg wit="V" type="add.">text1</rdg>
<rdg wit="S" type="add.">text2</rdg>
<rdg wit="SV" type="add.">text3</rdg>
</app>

I have several of these app elements and then there can be between 1 and 4 rdg elements within them, so I'm trying to write a foreach statement within a foreach statement but it is not working.

I want to say:

<xsl:for-each select="//tei:app">
    <li><xsl:value-of select="tei:lem"/><xsl:text>] </xsl:text>
        <xsl for-each select="tei:rdg"> <!--I hoping this would loop through each <rdg> within a given <app> element -->
            <xsl:value-of select="//tei:rdg"/>
            <xsl:value-of select="//tei:rdg/@type"/>
            <xsl:value-of select="//tei:rdg/@wit"/>
        </xsl:for-each>
    </li>
</xsl:for-each>

But right now this is not working. As it currently stands - this does the right number of loops but for every instance of rdg I'm getting the value of the fist rdg. But if I remove the double slashes in the three value-of elements, then I don't get any values.

Can you spot something I'm doing wrong? Sometimes I get pretty confused about the slash, double slash, no slash use in xpath -- could I be messing up there?

Thanks for your help.

Try this :

<xsl:for-each select="//tei:app">
    <li><xsl:value-of select="tei:lem"/><xsl:text>] </xsl:text>
        <xsl for-each select="tei:rdg"> <!--I hoping this would loop through each <rdg> within a given <app> element -->
        <xsl:value-of select="."/>
        <xsl:value-of select="@type"/>
        <xsl:value-of select="@wit"/>
        </xsl:for-each>
    </li>
</xsl:for-each>

In your inner loop your "current()" node is a tei:rdg node. So . access it's contents while @ access the various attributes.
