Answer 1

This should do it, not quite sure of the {name()} but you could replace that with "person"

> <xsl:template match="person">
>       <xsl:element name="{name()}">
>         <xsl:attribute name="id">
>           <xsl:value-of select="@name"/>
>         </xsl:attribute>
>         <xsl:attribute name="gender">
>           <xsl:value-of select="@gender"/>
>         </xsl:attribute>
>       </xsl:element>
>     </xsl:template>

Answer 2

This is very simple: Use the identity transform and create a template that transforms the name attribute:

<xsl:template match="node()|@*">
  <xsl:copy>
    <xsl:apply-templates select="node()|@*"/>
  </xsl:copy>
</xsl:template>

<xsl:template match="@name">
   <xsl:attribute name="id">
      <xsl:value-of select="."/>
   </xsl:attribute>
</xsl:template>

This will leave everything in the document except for name attributes exactly as it is. If you only want to change the name attribute on person elements, put a more restrictive XPath in the template's match attribute, e.g. person/@name.
