different cases differentiate and link them - xslt

Question

I've the below XML.
<orderedlist type="manual">
<item num="1."><para>identify the issues in dispute;</para></item>
<item num="1.1"><para>explore and generate options;</para></item>
<item num="1.1.1"><para>communicate with one another; and/or</para></item>
<item num="(i)"><para>copy of the cancellation of employment pass; and</para></item>
<orderedlist>
here i want to translate all the . to - in item-num and surround them with a different tag, where there is some number or period after . previously I've received a solution and I've used not(ends-with(./#num,'.')). That worked fine till some point, recently I've came across a situation(4th item num in the above XML) where in the item num has values like (i), i, a, a), and these also satisfy the condition and are getting the new tag. below is my XSL template.
<xsl:template name="orderedlist" match="orderedlist">
<ol class="eng-orderedlist orderedlist">
<xsl:apply-templates/>
</ol>
</xsl:template>
<xsl:template match="item">
<xsl:call-template name="paran"></xsl:call-template>
</xsl:template>
<xsl:template name="paran">
<xsl:apply-templates select="./para/node()[1][self::page]" mode="first"/>
<li class="item">
<div class="para">
<xsl:choose>
<xsl:when test="not(ends-with(./#num,'.'))">
<a name="{translate(./#num,'.','-')}"/>
<span class="phrase">
<xsl:value-of select="./#num"></xsl:value-of>
</span>
</xsl:when>
<xsl:when test="./#num">
<span class="item-num">
<xsl:value-of select="./#num"></xsl:value-of>
</span>
</xsl:when>
</xsl:choose>
<xsl:apply-templates/>
</div>
</li>
</xsl:template>
<xsl:template match="page[not(preceding-sibling::node()[not(self::text()) or normalize-space()])]"/>
here i don't want phrase around other numbers than i format X.X X.X.X.
you can find a demo of this issue here.
please let me know how can i fix it.
Thanks

Answer 1

Perhaps you need to add a check on whether the num attribute contains a full-stop in the first place
<xsl:when test="contains(#num, '.') and not(ends-with(./#num,'.'))">
i.e. #num contains a full-stop, but not one at the end.

Answer 2

I'd suggest you do it this way:
<xsl:template match="item">
<!-- do one thing here -->
</xsl:template>
<xsl:template match="item [not(ends-with(#num, '.'))] [not (translate(#num, '.123456789', ''))]">
<!-- do another thing here -->
</xsl:template>

Doing the predicate by regex as suggested by Ian Roberts would probably be more elegant.
