RE: (correction) [xsl] differences between x != 0 and not(x = 0)

One could also add up the values. If the sum is greater than 0, then one 
of the items was greater than 0.

<xsl:if test="sum(row/x) &gt; 0)">
  <!-- Do something here -->
</xsl:if>

Just a thought.

RE: [xsl] (correction)  [xsl] differences between x != 0 and not(x = 0)






The biggest difference with not() is that it will first check for 
existence the node and might fail on that account - not because the values 
are different.

But I think you can do a simpler test for your needs - how about this:

<xsl:if test="count(row/x[. != 0]) &gt; 0)">
                 <xsl:message>Error<xsl:message>
</xsl:if>

Sorry, this is what to accomplish:

1.
<row>
  <x>0</x>
</row>
<row>
  <x>4</x>
</row>
<row>
  <x>0</x>
</row>

The test should return FALSE

2.
<row>
  <x>0</x>
</row>
<row>
  <x>0</x>
</row>
<row>
  <x>0</x>
</row>

The test should return TRUE.

That is, when ALL nodes have value of 0, I have to do something, and when 
at least one x has a value different from 0, I want to do other thing. I 
want to use <xsl:if>, not <xsl:choose>

Thanks
Jaime

Asunto: [xsl] differences between x != 0 and not(x = 0)

Hi all..

I always forgot this thing.

If I want to test that all nodes has value different from 0, I have to
use x!=0 or not(x=0) ?

For example,

<row>
  <x>0</x>
</row>
<row>
  <x>4</x>
</row>
<row>
  <x>0</x>
</row>

The test for the above example should return TRUE.

<row>
  <x>0</x>
</row>
<row>
  <x>0</x>
</row>
<row>
  <x>0</x>
</row>

The test for the above example should return FALSE.

Thanks
Jaime
