$NEST|$INEST : less than L loops - JJoe - Dec. 18, 2009 07:50 PM

Code:

[Patterns]

Name = "$NEST less than L loops"

Active = FALSE

Limit = 25600

Match = "<(table)\1"

        "$SET(L=iii)"

        "&"

        "$NEST(<$TST(\1)"

        "($SET(c=$GET(c)i)(^$TST(c=$TST(L)))"

        "|$SET(L=)$SET(c=))$TST(L=ii+),</$TST(\1) >)"

        "$TST(L=ii+)"

        "$SET(L=)$SET(c=)"

Test against:

Code:

<table>III

<table>II

<table>I

</table>

</table>

</table>

Result:

Code:

<table>III

</table>

Change iii in $SET(L=iii) to vary maximum number of loops allowed,
ii is less than two,
iii is less than three,
etc.

Basic idea should also work with $INEST.
More tests can be added.

I haven't done much with it.
Report oddities.

Have fun

Nice lesson JJoe! With your permission i will add it to the base config in the section Code examples with the title "<example> $NEST less than L loops {JJoe}091218"

Just make sure it works. Wink

My hope was to save some time and buffer space,
$NEST(<table,</table >) can use a lot of both before it fails.
Testing seemed to show success.

The posted example counts 'loops'.
<table><table></table><table></table></table>
is three loops.

It is also possible to count 'layers'.
<table><table></table><table></table></table>
would be two layers, iirc.

Have fun
