[xsl] analyze string issues

[Terry Ofner <tofner@xxxxxxxxxxx>]

I am having trouble stripping numbers from a list of items. Here is a  
snippet of my xml:

<book>
<stem>	1.	Read the sentence... </stem>
<stem>	2.	What language is the word <i>defense</i> originally from?</ 
stem>
</book>

My current template is

<xsl:template match="stem">
	<xsl:analyze-string select="." regex="\t[0-9][0-9]?\.\t">
	 <xsl:non-matching-substring>
		<stem><xsl:copy-of select="."/></stem>
	</xsl:non-matching-substring>
	</xsl:analyze-string>
</xsl:template>


The template does what I want. It removes the tabs, numbers, and  
periods. But it also removes the <i> elements so that I end up with

<book>
<stem>Read the sentence... </stem>
<stem>What language is the word defense originally from?</stem>
</book>

How can I strip off the numbers and retain the inline elements of the  
<stem> element?
