First note that the tree on which XSLT operates never contains a character or entity reference, it simply contains an Unicode character. To match on and replace an Unicode character with an element you can use analyze-string:
<xsl:stylesheet
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="2.0">
<xsl:template match="#* | node()">
<xsl:copy>
<xsl:apply-templates select="#* , node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="p//text()">
<xsl:analyze-string select="." regex=" ">
<xsl:matching-substring>
<s/>
</xsl:matching-substring>
<xsl:non-matching-substring>
<xsl:value-of select="."/>
</xsl:non-matching-substring>
</xsl:analyze-string>
</xsl:template>
</xsl:stylesheet>
That way an input document like
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE doc [
<!ENTITY nbsp " ">
]>
<doc>
<p>This is a paragraph with a non-breaking space before some sub text.</p>
</doc>
is transformed into the result document
<?xml version="1.0" encoding="UTF-8"?><doc>
<p>This is a paragraph with a non-breaking space <s/> before some sub text.</p>
</doc>
