replacing characters in a string

---

---

Hi, 

After reading Michel Goosens mail about "how to get an apostrophe into a
test expression" and Mike Kay's answer, I've been trying to do something
similar: 

<xsl:variable name="v1" select="string(name)"/>
<xsl:variable name="v2">
		<xsl:choose>
		<xsl:when test='substring($v1, 1)="&apos;"'>
			<xsl:value-of select="substring-before"/>
				<xsl:text>\'</xsl:text>
			<xsl:value-of select="substring-after"/>
		</xsl:when>
		<xsl:otherwise>
			<xsl:value-of select="$v2"/>
		</xsl:otherwise>
		</xsl:choose>
	</xsl:variable>

What I want this to do is convert the (contents of the) 'name' element in my
XML to a string, see if there's an apostrophe character, if so, convert this
to \', if not, just output the value of 'name'. ($v2 is used in a parameter
for a javascript function). 

But I always get the value of 'name'. I tried other tests, but the tests
always fail. 

Any insights? 

Linda
