Apply a function to a result

[Wiszh]

I am trying to select a series of attributes and apply a function to them:
For example
//row/@role
I want to apply the substring function to the role attribute. If I add it to the entire xpath then I only get one result
substring(//row/@role, '3')

If I apply the function to the attribute only I get an error:
//row/[substring(@role, '3')]

Any ideas???

<xsl:for-each select="//row">
  <xsl:value-of select="substring(@role, 3)"/>
</xsl:for-each>

Avoid using //, it will search every node. Where possible specify the full path.

Thanks, for your reply.

I realize that it can be performed as a two step process, but is there any way to do this in one step?
(I am trying to use c# XmlNode.selectNodes(xpath here) for this.

Thanks again
