Modify attribute value in XSLT and call template again for second time

Answer 1

From http://www.w3.org/TR/xslt#modes

Modes allow an element to be processed multiple times, each time producing a different result.

This stylesheet:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"&gt;
    <xsl:template match="Rows">
        <ul>
            <xsl:apply-templates/>
        </ul>
        <table>
            <xsl:apply-templates mode="table"/>
        </table>
    </xsl:template>
    <xsl:template match="Row">
        <li>
            <xsl:value-of select="@Data1"/>
        </li>
    </xsl:template>
    <xsl:template match="Row" mode="table">
        <tr>
            <xsl:apply-templates select="@*" mode="table"/>
        </tr>
    </xsl:template>
    <xsl:template match="Row/@*" mode="table">
        <td>
            <xsl:value-of select="."/>
        </td>
    </xsl:template>
</xsl:stylesheet>

With this input:

<Rows>   
  <Row Style="OutputTemplateName" Data1="Data1Value" Data2="Data2Value" />   
  <Row Style="OutputTemplateName" Data1="Data1Value" Data2="Data2Value" />   
</Rows>  

Output:

<ul>
    <li>Data1Value</li>
    <li>Data1Value</li>
</ul>
<table>
    <tr>
        <td>OutputTemplateName</td>
        <td>Data1Value</td>
        <td>Data2Value</td>
    </tr>
    <tr>
        <td>OutputTemplateName</td>
        <td>Data1Value</td>
        <td>Data2Value</td>
    </tr>
</table>
