Hola,
Posiblemente funcione así:
Código xml:
Ver original<xsl:template match="/">
<pre>
<xsl:for-each select="seccion">[TITLE]<xsl:value-of select="normalize-space(title)"/> : [/TITLE]<xsl:for-each select="para">
<xsl:apply-templates select="."/>
</xsl:for-each>
</xsl:for-each>
</pre>
</xsl:template>
<xsl:template match="para/def">[DEF]<xsl:value-of select="normalize-space(.)"/>[/DEF]</xsl:template>
<xsl:template match="para/text()">[BLANK]<xsl:value-of select="normalize-space(.)"/>[/BLANK]</xsl:template>
Saludos,
