RE: given @id="1.2.3" .... -1 || +1 to the "3" in @id

Anthony,
<xsl:value-of select="regExp:match(., '[0-9]+|\.', 'g')[5]" /> should do it.
Or
<xsl:value-of select="regExp:match(., '[0-9]+|\.',
'g')[count(regExp:match(., '[0-9]+|\.', 'g'))]" /> for any .00.00.00.00 Or
use tokenize
str:tokenize(., '.')
