Question

XPATH question (again)

  • May 17, 2012

Here's my structure (Styler 5.4):


<condtinsp>
<inspection>
<condition></condition>
<req></req>
</inspection><inspection>
<condition></condition>
<req></req>
</inspection><inspection>
<condition></condition>
<req></req>
</inspection><inspection>
<condition></condition>
</condtinsp>


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:


    <enumerat increm="1" enumid="conditionct"/">
    <usetext source="conditionct,\.\,@10pt" placemnt="before"></usetext>


    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>


    <inspection>
    <condition></condition>
    <req></req>
    </inspection>
    <inspection>
    <condition></condition>
    <req></req>
    </inspection>
    <inspection>
    <condition></condition>
    <req></req>
    </inspection>


    <syshd></syshd>


    <inspection>
    <condition></condition>
    <req></req>
    </inspection>
    <syshd></syshd>
    <inspection>
    <condition></condition>
    <req></req>
    </inspection>


    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
