Hi David,

Assuming that your strings are always of the form:


(where D is a digit) you could use:

PR_<xsl:value-of select="b310" />
PR_<xsl:value-of select="substring(b310, 1, 2)" />
PR_<xsl:value-of select="substring(b310, 4, 3)" />
PR_<xsl:value-of select="substring(b310, 8, 3)" />

If the lengths of the different parts of the strings can vary, then
you need to use substring-before() and substring-after():

PR_<xsl:value-of select="b310" />
PR_<xsl:value-of select="substring-before(b310, '/')" />
PR_<xsl:value-of select="substring-before(
                           substring-after(b310, '/'), ',')" />
PR_<xsl:value-of select="substring-after(
                           substring-after(b310, '/'), ',')" />

If there can be more parts to the string, then you need a recursive
solution.  If that's the case, then can you write a general pattern
for the string, and we'll try to work something out?
I hope that helps,
