Regex problem

Stephen Walch

10/30/2002 12:54:00 PM

I am using the following code to parse a string of name value pairs like
"name1=value1; name2=value2"

// Managed C++
Regex* r = new
Regex("(?<name>\\w+)=(?<value>(\\w[\\w\\s\\/\\-_\\.\\:\\\\=]*)?\\w)");
Match* m;
for (m = r->Match(m_sConnectionString); m->Success; m = m->NextMatch())
{
String* name = m->Groups->get_Item("name")->Value->ToLower();
String* value = m->Groups->get_Item("value")->Value;
}

Works ok, but when an illegal character is encountered in a name or value,
NextMatch() simply returns NULL as if it were at the end. How can I tell if
the matches I got represented the entire string or not?

Thanks!

Hi Stephen,

Since we can get the length of the string, we can check that if it is the
end of the string when Match.NextMatch() return null.
