Re: [xsl] Select with multiple conditions?

["Wendell Piez wapiez@xxxxxxxxxxxxxxx" <xsl-list-service@xxxxxxxxxxxxxxxxxxxxxx>]

Ouch the send button hit itself sorry!

2nd expression rewritten:
<xsl:for-each select="child::*[@level = 'series' or @level = 'subseries']">

but we need XPath 2.0 to say
<xsl:for-each select="child::*[@level = ('series', 'subseries')]">

Cheers, Wendell
