Error in Regexp: matches does not match?

The regexp function was replaced in DOORS 9. I think you can find some info in the DOORS help. Regards, Mathias

I have done some tests:

(^x$)|(^y.)

works. Also

^(x|y.)$

works.
For me it seems, that it is not possible to have a line end in an alternative: '$|',

Does anybody know, which regexp code is used in DXL?

Wrote this to experiment with regex. Use and abuse as you see fit.

DBE rgx = null
DBE str = null
DBE rst = null
 
void doit (DB calledfrom)
{
    string r = get (rgx)
        string s = get (str)
        Regexp x = regexp2 r
        if (x s) set (rst, s[match 0])
        else set (rst, "no match...")
        return
}
 
DB db = centered "Regex Experiment"
rgx = field (db, "Regex:", "", 60, false)
str = field (db, "String:", "", 60, false)
rst = field (db, "Matches:", "", 60, true)
apply (db, "   Go   ", doit)
show db

Again, it's kind of hard, just looking at your code examples, to decipher what you want the regex to do... One problem I'm having interpreting your examples is that the caret (^) and dollar ($) characters mean different things depending on how they're used. The caret means "start of string" normally, but in range brackets it negates. The dollar means "end of string" normally. But it also has another use, which escapes me presently.

Add a field 'Matches1' that uses the lagacy 'regexp' function (instead of regexp2); so perhaps someone can see a difference.

DBE rgx = null
DBE str = null
DBE rst1 = null
DBE rst2 = null
 
void doit (DB calledfrom)
{
    string r = get (rgx)
        string s = get (str)
        Regexp x1 = regexp r
        Regexp x2 = regexp2 r
        if (x1 s) set (rst1, s[match 0])
        else set (rst1, "no match...")
        if (x2 s) set (rst2, s[match 0])
        else set (rst2, "no match...")
        return
}
 
DB db = centered "Regex Experiment"
rgx = field (db, "Regex:", "", 60, false)
str = field (db, "String:", "", 60, false)
rst1 = field (db, "Matches1:", "", 60, true)
rst2 = field (db, "Matches2:", "", 60, true)
apply (db, "   Go   ", doit)
show db

hi,

I have a string by name "Test"
i have a list of groups like
1. AI_Hello-Test_PMs
2. AI_Hello-Test-2.5_PMs
3. AI_Hello-Test-2_PMs

so what i am trying to do is
for g_All in groupList do
{
s1 = g_All.name
s_ProjectName = "Test"
Regexp r = regexp s_ProjectName
if(r s1)
{
print "...."s1
}
}
the output is
.... AI_Hello-Test_PMs
....AI_Hello-Test-2.5_PMs
....AI_Hello-Test-2_PMs

in the above code it is displaying all the groups which all are containg the string "Test", but what i want is it should display only the group which has the text "Test" like only the group "AI_Hello-Test_PMs".

Please help me in this.

Kindly let me know if this possible.

Thank you!

Regards,
Shruthi
