David has given both a 2.0 and a 1.0 solution. I wouldn't write
anything different for what David wrote for XSLT 2.0.

But here's a slightly different 1.0 solution,

<xsl:stylesheet xmlns:xsl=3D"http://www.w3.org/1999/XSL/Transform"
                       version=3D"1.0">

 <xsl:output method=3D"xml" indent=3D"yes" />

 <xsl:template match=3D"x">
   <result>
     <xsl:apply-templates select=3D"field[heading]" mode=3D"a" />
   </result>
 </xsl:template>

 <xsl:template match=3D"field" mode=3D"a">
   <fieldset>
     <legend><xsl:value-of select=3D"heading" /></legend>
     <xsl:apply-templates select=3D"following-sibling::field[1][text]"
mode=3D"b" />
   </fieldset>
 </xsl:template>

 <xsl:template match=3D"field" mode=3D"b">
   <p><xsl:value-of select=3D"text" /></p>
   <xsl:apply-templates select=3D"following-sibling::field[1][text]"
mode=3D"b" />
 </xsl:template>

</xsl:stylesheet>

this is popularly known as the sibling recursion technique.
