xpath for-each multiple conditions

What is wrong with the following line?

<xsl:for-each select="//Node1/Node2/Node3 [.!='Primary' or .!='Secondary' ]">

Trying to select all elements where Node3 is not Prim开发者_StackOverflowary o Secondary.

Thanks.

I think you want to find Node3 where the content is not Primary and not Secondary.

<xsl:for-each select="//Node1/Node2/Node3[.!='Primary' and .!='Secondary' ]">

not(. = 'Primary' or . = 'Secondary')
