Hi, I'm having problems with string.split()
My problem is;
I have a sentence which the user inputs, I then input a word and the number of times that word appears in the sentence is displayed.
Is there a regex expression which will exclude every word except "word" which I entered. So that words.length will actually display the number of "word" in the sentence.
Here is some of my code; The ??!word?? is where I'm stuck. Is this a valid approach? Even if I skip the sentence2.split (word) I get only 1 word being counted, which isnt right when theres more than 1 word in the sentence.
String sentence1 = sentence.trim() ;
String sentence2 = sentence1.split ("\\s+");
word = GetWord();
String words[] = sentence2.split (??!word??);
DisplayWord(wor ds);
I've played around with sentence.compar eTo() as well, to iterate through the sentence comparing each string to word, but it hasnt worked either. My output was always no word present.
My DisplayWord code is just an if-else statement (if word.length > 0).
Thanks for any help anyone can provide. Much appreciated.

Run through this and you should be able to get it right. You can always post again of course if you still have problems with it.

Have a look at the String.indexOf( "word", startPos) method and use it
in a loop where you count the successful matches.
kind regards,

For each run of my app, I have a known set of (<100) wafer names.
Names are sometimes simply integers, sometimes a short string, and
sometimes a short string followed by an integer, e.g.:
5, 6, 7, 8, 9, bar, foo_6, foo_7, foo_8, foo_9, foo_10, foo_11
I need to read user input of a subset of these. The user will type a
set of names separated by commas (with optional white space), but there
may also be sequences indicated by a dash...

Hi All,
What I want to is using a string as PATTERN in a split function. This makes
it possible for me to change the PATTERN on one place in my script...
For example:
$separator = ";";
$line = "field1;value1";
local($field, $value) = split(/$separator/, $line);

I want to compare strings of numbers that have a circular boundary
condition. This means that the string is arranged in a loop without an
end-of-string. The comparaison of two strings now becomes a different
operation than with regular strings because the circular string can be
"rotated", like this:
1 2 3 4 5
2 3 4 5 1
3 4 5 1 2
4 5 1 2 3

I'm calling string.Split() producing output string. I need direct
access to its enumerator, but would greatly prefer an enumerator
strings and not object types (as my parsing is unsafe casting from
object to string frequently). Basically generics and not its non-
generic counterpart.
string str1 = "abc: value1 def: value2 ghi: value3";
char delimiterChars = { '\t' };
string tokens = str1.Split(delimiterChars);
