Using XSLT to Change Variations of Ellipsis Symbol to Standard

I need to replace all variants of ellipsis with a specific (typographically correct) version. This symbol can occur in just about any text node. It can come as ". . ." or "..." or "…" (HTML entity) with spaces/characters/end of tag before/after it.

The best for layout is as dots and thin-spaces: ". . ."

The following solution finds the all the ellipsis in the test file (and fixes them correctly) EXCEPT when there are multiple ellipsis per node (last para tag). So close, yet so terrifyingly far away.

Due to the inability to see clearly whether or not it changed spaces to thin spaces I added the text line. Obviously in a final solution this would be removed.

XSLT:

<xsl:stylesheet xmlns:xsl="http://ift.tt/tCZ8VR"
xmlns:xs="http://ift.tt/tphNwY"
exclude-result-prefixes="xs"
version="2.0">

<!-- Identity template for all other elements and attributes. -->
<xsl:template match="@*|node()" name="default" mode="#all">
    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:apply-templates mode="#current"/>
    </xsl:copy>
</xsl:template>


<xsl:template match="text()[matches(.,'\.\s?\.\s?\.')]">
    <xsl:analyze-string select="." regex="(\w?\.?)\s?\.\s?\.\s?\.\s?(\w?)">
        <xsl:matching-substring>
            <xsl:if test="regex-group(1)"><xsl:value-of select="regex-group(1)"/><xsl:text>&#x2009;</xsl:text></xsl:if>
            <xsl:text>.&#x2009;.&#x2009;.</xsl:text>
            <xsl:text>[[FIXED TEXT]]</xsl:text>
            <xsl:if test="regex-group(2)"><xsl:text>&#x2009;</xsl:text><xsl:value-of select="regex-group(2)"/></xsl:if>
        </xsl:matching-substring>
        <xsl:non-matching-substring><xsl:value-of select="current()"/></xsl:non-matching-substring>
    </xsl:analyze-string>
<!--        <xsl:value-of select="replace(.,'(\w?\.?)\s?\.\s?\.\s?\.\s?(\w?)', '$1&#x2009;.&#x2009;.&#x2009;.&#x2009;$2')"/>-->
</xsl:template>

<xsl:template match="text()[matches(.,'&#x2026;')]">
    <xsl:analyze-string select="." regex="(\w?\.?)\s?&#x2026;\s?(\w?)">
        <xsl:matching-substring>
            <xsl:if test="regex-group(1)"><xsl:value-of select="regex-group(1)"/><xsl:text>&#x2009;</xsl:text></xsl:if>
            <xsl:text>.&#x2009;.&#x2009;.</xsl:text>
            <xsl:text>[[FIXED SYM]]</xsl:text>
            <xsl:if test="regex-group(2)"><xsl:text>&#x2009;</xsl:text><xsl:value-of select="regex-group(2)"/></xsl:if>
        </xsl:matching-substring>
        <xsl:non-matching-substring><xsl:value-of select="current()"/></xsl:non-matching-substring>
    </xsl:analyze-string>
<!--        <xsl:value-of select="replace(.,'(\w?\.?)\s?&#x2026;\s?(\w?)', '$1&#x2009;.&#x2009;.&#x2009;.&#x2009;$2')"/>-->
</xsl:template>
