How would I get the last character of a string in XSLT in order to add it to my HTML output?

Question

I am very new to XSLT and need to grab only the last letter of an XML value and add that character to my HTML output.

Answer 1

Use the XPath expression

substring(., string-length(.), 1)

or, in an XSLT way

<xsl:value-of select="substring(., string-length(.), 1)" />

This works, because XPath starts counting at 1 and not 0.
