Element End Flag

Element End Flag

Is there an ACL command to determine the end of an element ?

Whilst reading an XML file from top to bottom I am setting a flag when I come across a table for example:

if( oid_name(this_o) == "table" ){
in_table=1;
}

How do I turn the flag off when I get to the end of the table element?

Is there an oid command for this ?

Regards,

Andy

Can you show more of your code, so we can see exactly how you're
traversing the document?  Depending on how you're doing this, you'll
probably "pass by" the table again on your way out of it, so you can
reset your flag.

Remember, the document is modeled like a tree, with each element
forming a branch.  You pass through the table "node" to enter its
branch and you'll pass through that node again on the way back out.

I'm simply using the following for loop from the top :

for( ; oid_valid( this_o )&&!dm_end; this_o = oid_forward( this_o ) ) {

if( oid_name(this_o) == "table" ){
in_table=1;
}

etc..

}

I don't know what you are doing or why or what other constraints there might
be (that's my -- I'm about to tell you to do something totally different
please don't take offense because maybe I'm wrong and you are right plus
even if your scenario is most efficiently and extensibly and maintainably
solved in a linear way someone who has not thought it through might benefit

For example, say that you want to process all paragraph elements only if
they are located within a table.

Then you ask (I'll do it almost declaratively here rather than
imperatively as you're doing) to create an array with all paragraph
elements that verify this condition



$c = xpath_nodeset($a, "para[ancestor::table]") # get all para elements
that have a table ancestor



This will return in $c the number of paragraph elements matching the
condition (that is, that are contained in a table) and the array of all
paragraph elements in $a; then you navigate $a and do what you want on
the elements



for ( $i in $a )

{

# do something on $a[$i]

}



Please explain your functional requirement so that it would be easier to
advise on the best idiom to use
