Search for particular string in patttern

Hello ...

Entry=hiCreateListBoxField(
?name 'Entry
?multipleSelect t
?choices (list "x_y_1 (diodes)" "x_y_10 (clamps)" "x_y_11 (Protections)" ))

rules_check = buildString(
foreach(mapcar entry form->Entry->value
car(parseString(entry))
)
" "
)
multi_check = parseString(rules_check)
numPat=pcreCompile("\\d")
rules_number=buildString(
foreach(mapcar entry form->Entry->value
pcreExecute(numPat entry)
pcreSubstitute(numPat "&")
)
","
)

when am running above code am getting values of rules_number = 1,1,1 inspite it should be 1,10,11

where in code its wrong and how can i correct it?

Hi,

Your pcre is wrong, it can only match one digit (not a full number)

Add a "+" at the end and it should work correctly

numPat=pcreCompile("\\d+")

Note that pcreSubstitute relies on rexMagic, if anywhere in your Virtuoso session (rexMagic nil) is set your code will return "&","&","&" instead of "1","10","11"

Hope this helps,

Cheers,

Aurélien

pcreSubstitute(numPat "\\0")

That will have the same behaviour as using &. Your pattern is wrong either way and this won't fix your incorrect regular expression.

This is undocumented behaviour, and nobody should write code that depends upon it (I'm pushing for this to be fixed, because I think it's bad behaviour that can cause code to break).
