Re: [xsl] Select with multiple conditions?

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

Michele,

As Eliot notes, the pipe operator in XPath is shorthand for "union", not
"or", although there are places (such as a match pattern) when a union
("give me As and Bs") can look and work like an "or" ("give me things that
are A or B").



So spelled out into long syntax (and keeping only two cases) your first
for-each looks like


<xsl:for-each select="child::*[attribute::level = 'series'] union
child::*[attribute::level = 'subseries']">




borb statements inside the attribute match



<xsl:for-each select="child::*[@level = 'collection' | 'recordgrp' |
'series'  | 'subseries']">
