How to open a tree to a specific node? (Apex 19.2)

John like many othersOct 26 2020 — edited Oct 26 2020

Hello
I would like to open a tree to a specific hierarchical position after it was refresh (comes in closed state).
Based on the tree widget API I assume I have to open all nodes above the target. I can get all the NodeIDs before I would refresh the treeView: getExpandedNodeIds() but there are two problems with that:
This function returns the Node IDs not in a sorted way (from root to target node)
The Node ID is not stored in the HTML structure, so can't be referenced that way
The nicest/easiest way would be to hand over a jQuery object or a DOM object that defines the target node to which the tree should be expanded. Is something like this available and I didn't see it? If not, is there any other way to get the tree expanded to a specific node?

Remove 2 brackets:
SQL> select case when regexp_like(regexp_replace( ' 123 4567 890', ' ' ), '^([0-9]{9}|[0-9]{12})$')
  2  then 'Match Found'
  3  else 'No Match Found'
  4  end as test
  5  from dual;

TEST
--------------
No Match Found

SQL> select case when regexp_like(regexp_replace( ' 123 4567 89', ' ' ), '^([0-9]{9}|[0-9]{12})$')
  2  then 'Match Found'
  3  else 'No Match Found'
  4  end as test
  5  from dual;

This is too fast a reply, and thanks for correcting my basic understanding. The same expression (my old) will work for javascript, but there is this slight difference between the handling regular expression in database and UI :)

Umm. Regex of Oracle has not supprted "Tanaka Akira Special" yet. :-(
with t(Val) as(
select ' 123 4567 890' from dual union all
select ' 123 4567 89'  from dual)
select Val,
case when RegExp_Like(replace(Val,' '),'^[0-9]{9}([0-9]{3})?$')
     then 1 else 0 end as result
  from t;

VAL            RESULT
-------------  ------
 123 4567 890       0
 123 4567 89        1
1 - 4
