I need to be able Count text as well as numbers and I can't seem to get either to work.

Also, is it possible to count against the content of another element?

Can you provide a practical example of what you are trying to do?

Thanks,

Idealy I would like to something along the lines of

<xsl:value-of select="count(/Nodes/Node[text()=someword])" />

That will return you the number of Node elements whose text matches "someword" (provided that "someword" is enclosed in single quotes in that instruction)... what's wrong with it?

Ah the single quotes was the issue. Thanks

I also need to do a second type of count.
eg

count the amount of items between two node values.

Is this possible? If it isn't, is it possible to count against on node value?

Thanks

These all seem to imply different kind of filters that you would have to specify in the XPath expression...

count(/Nodes/Node[. > 10 and . < 20]) (assuming the value of "Node" is numeric)
count(/Nodes/Node[. = 'some value'])
...

thats fine but it doesn't work when i want to use values that are dynamic. By that i mean the 10 and 20 are node values and not knwon values i manually enter in

It will work as long as you provide the proper XPath to reach the elements that contain the "dynamic" values you are looking for... something like:

count(/Nodes/Node[../NodeThreshold1 > 10 and /Nodes/MyTopNode < 20])

Sorry, maybe I am not explaining this correctly

I need to do this

count(/Nodes/Node[. > NodeThreshold1 and . < NodeThreshold2])

...same concept... you will need to use the proper XPath to reach the dynamic thresholds.
