You can use the fact that calling document('') with no parameter will
return the stylesheet, so you can then iterate through the templates
extracting the elements you need.

This stylesheet:

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

<xsl:template match="/">
  <xsl:for-each select="document('')/*/xsl:template/h1">
    <xsl:element name="{local-name()}">
      <xsl:value-of select="."/>
    </xsl:element>
  </xsl:for-each>
</xsl:template>

<xsl:template match="one">
  <h1>heading one</h1>
</xsl:template>

<xsl:template match="two">
  <h1>heading two</h1>
</xsl:template>

</xsl:stylesheet>

When applied to itself, produces:

<h1>heading one</h1><h1>heading two</h1>
