[xsl] select first word

[Jim_Albright@xxxxxxxxxxxx]

starting with
<input>
        <le>Saint, sainteti</le>
        <le>Timoignage, timoigner, timoin</le>
        <le>Tablettes de l'alliance</le>
        <le>Satan</le>
</input>

I want

<output>
        <le>Saint</le>
        <le>Temoignage</le>
        <le>Tablettes</le>
        <le>Satan</le>
</output>

I have
        <xsl:value-of select=
"translate(.,'abcdehijklmnorstuvyz{|HIJKA@','aaaaaeeeeiiiioooooEEEEAA')"/>

to translate the accents to the unaccented words

and

        <xsl:value-of select="substring-before(.,' ')"/>
        <xsl:value-of select="substring-before(.,',')"/>

will select just the first word.

So how do I put this together?
