XPATH question (again)

cleccese · ‎May 17, 2012

Here's my structure (Styler 5.4):

I want to number the condition tags but only if they have content (they have no title so making them a Formal Block didn't help) with the XPATH count(../preceding::condition) + 1

I created a content test condition for the XPATH on <condition> in Styler so only the non-empty conditions are numbered, but the counter is incrementing on the empty conditions. So the first three numbered <condition>s are numbered 1, 9, 10 because there are 8 empty conditions following the first numbered one.

I don't know how to keep the empty <conditions> from incrementing the counter, or if that is even possible. Some kind of subtraction, maybe?

Thanks for any ideas!

Using FOSI terminology, this might work:

You could put a savetext with a conrule (construction rule) of #CONTENT in the e-i-c (element-in-context) for <condition>.

Then you could have an attribute rule to check if this savetext had a value of #ANY and then increment the counter.

Assuming that your structure is consistent and the <condition> element is always a child of <inspection>, you would need to reset this savetext to be equal to "\\" (null or empty in FOSI talk) in the e-i-c for <inspection>.

Hi Caroline--

You probably want something like this:

count(../preceding-sibling::condition[not(* | text())])+ 1

HTH.

Your XPath counts all preceding conditions, but you only want to count the
ones that have a child node, so try something like
"count(preceding::condition[node()]) + 1". If you have "empty" conditions
that get counted because of some whitespace inside of them, try
"count(preceding::condition[* or normalize-space(.)]) + 1".

Oops, I got it backward, that one will count only the conditions you
*don't* want. Here's the right version:

count(../preceding-sibling::condition[boolean(* | text())])+ 1

Thank you everyone! Brandon's worked.

Although this morning I realized I could simply increment and output a counter in FOSI in the non-empty content condition I had set up for <condition> in Styler:

I should have figured this out before posting but I do keep all the responses to my XPATH questions in a file which I refer back to constantly, so I appreciate everyone's help.

Whoops! <condition> has to reset when it hits<syshd>

<syshd></syshd>

Thanks to Brandon's response to another thread, I figured it out to be:

count(preceding::condition[node()]) - count(preceding::syshd[1]/preceding::condition[node()]) + 1
