I'm trying to produce a single style sheet (foo.xsl) that offers the
following functionality. I'm using IE 5.5. Any help would be greatly
appreciated.

And having a document:

<doc>
        <ele name1="A1" name2="A2" name3="A3"/>
        <ele name1="B1" name2="B2" name3="B3"/>
</doc>

processed through the same tyle sheet (foo.xsl) produces:

<TABLE>
        <TR>
                <TH>name1</TH>
                <TH>name2</TH>
                <TH>name3</TH>
        </TR>
        <TR>
                <TD>A1</TD>
                <TD>A2</TD>
                <TD>A3</TD>
        </TR>
        <TR>
                <TD>B1</TD>
                <TD>B2</TD>
                <TD>B3</TD>
        </TR>
</TABLE>

A couple of observations:

(1) The below works as long as the <ele> elements each has the same number of attributes, with the same names. If one <ele> has 4 attributes and one has 3, for example, then it will break.

(2) I tested this with both of your examples under IE5.5 (July preview) release Also with Saxon; output from Saxon was:

<html xmlns="http://www.w3.org/TR/REC-html40";>
  <head><title>Attributes to Elements</title></head>
  <body>
    <table>
      <tr>
        <td>A1</td>
        <td>A2</td>
        <td>A3</td>
      </tr>
      <tr>
        <td>B1</td>
        <td>B2</td>
        <td>B3</td>
      </tr>
    </table>
  </body>
</html>

(3) General idea is to: (a) Build the root of the result tree to correspond to your root <doc> element; this result tree includes a <table> element. (b) Then there's a template rule which handles the <ele> elements. Within this template rule, if this is the first <ele>, put the table headers into the rsult tree, values coming from the attribute names for this first <ele>. Then all the attributes are processed, values being placed into <td> elements.

<?xml version="1.0"?>
<xsl:stylesheet version="1.0"
  xmlns:xsl="http://www.w3.org/1999/XSL/Transform";
  xmlns="http://www.w3.org/TR/REC-html40"; >

  <xsl:template match="/doc">
    <html>
      <head><title>Attributes to Elements</title></head>
      <body>
        <table>
          <xsl:apply-templates />
        </table>
      </body>
    </html>
  </xsl:template>

  <xsl:template match="ele">
    <xsl:if test="position()=1">
      <tr>
        <xsl:for-each select="@*">
          <th><xsl:value-of select="name()"/></th>
        </xsl:for-each>
      </tr>
    </xsl:if>
    <tr>
      <xsl:for-each select="@*">
        <td><xsl:value-of select="."/></td>
      </xsl:for-each>
    </tr>
  </xsl:template>

</xsl:stylesheet>
