I would suggest using XSLT 2.0 or XSLT 1.0 + tokenize extension function
to do this, then you write something like the following:

<xsl:template match="txt">
  <txt>
    <xsl:for-each select="tokenize(.,'\s')">
        <xsl:copy-of select="."/>
        <xsl:if test="position() mod 15 = 0"><br /></xsl:if>
    </xsl:for-each>
    ...


If you are using XSLT 1.0 + extensions then the tokenize funtion would
need be in the processors namespace (for example saxon:tokenize(...))

I'm sure there's a few gotchas with using the \s character class for
this task, but I (still) don't know regexs well enough to come upu with
anything better.
