help with iRules Regex scan statement.

Why not just use split and then extract the field via lindex?

 

 

% set testuri "/mapper/time_map/datatype/comtype/37.777125/-122.419644/13/1309/3164.json?v=1°ree_buffer=0.002&callback=jQuery1720814429080274308_1339544764657&_=1339544771741"

 

/mapper/time_map/datatype/comtype/37.777125/-122.419644/13/1309/3164.json?v=1°ree_buffer=0.002&callback=jQuery1720814429080274308_1339544764657&_=1339544771741

 

 

% set split [split $testuri /]

 

{} mapper time_map datatype comtype 37.777125 -122.419644 13 1309 3164.json?v=1°ree_buffer=0.002&callback=jQuery1720814429080274308_1339544764657&_=1339544771741

 

 

% puts "[lrange $split 4 6]"

 

comtype 37.777125 -122.419644

 

% puts "[lindex $split 4]"

 

comtype

 

 

The scan statement will still work, but it seem it has troubles with the / being the first character, so this will work:

 

 

 

% scan $testuri {/%*[^/]/%*[^/]/%*[^/]/%[^/]/%[^/]/%[^/]} one two three

 

3

 

% puts $one

 

comtype

 

% puts $two

 

37.777125

 

% puts $three

 

-122.419644

 

Nice work MiLK_MaN. I think the single scan command should be more efficient than split with lindex, etc.

Thank MiLK_MaN this works. Btw what editor/shell are you using the check test the irules?

Just tclsh in a Mint Debian virtual machine on my home ESX server :)
