you can test it on this xml file:
.....
<caption>R&eacute;partition&nbsp;des&nbsp;alimentations&nbsp;dans&nbsp;la&nbsp;baie&nbsp;SK&nbsp;(vue&nbsp;avant)</caption>

......

try to get the caption and translate each &nbsp; to '-'
with the instruction:
<xsl:value-of select="translate($caption_title,' ','-')"/>
or
<xsl:value-of select="translate($caption_title,' @#160;','--'"/> as you
say.

the result is:
Répartition des alimentations dans la baie SK (vue avant)
but you should get :
Répartition-des-alimentations-dans-la-baie-SK-(vue-avant)
