XF 2.2 Looping through a foreach and counting the results

[Lee]

If I have the following code:

<xf:foreach loop="$foobar" value="$foo">
</xf:foreach>

Is it possible to cumulatively check the value of a result and check to see if it is not null?

For example if I had 10 results I would like to read the following field:

$foo.xyz

And display some text if any of them return null.

    <xf:else />
        value is null, empty, or possibly 0
    </xf:if>
</xf:foreach>

    <xf:else />

    </xf:if>
</xf:foreach>

Would that work if there were instances were $foo.xyz was 1 and instances were it were 0?

The above will work with 0 in a template (I believe it is treated as a string and not a number). To test explicitly for a 0 or a 1:

<xf:if is="$foo == '0' OR $foo == '1'">

<xf:else />

</xf:if>

I tested it, it does exactly what I want, thank you again Lawrence.
