Count occurences of subsring in string

I am using cfhttp to return an hmtl table. I would like to
"count' the number of "<tr>" tags in the cfhttp.filecontent
variable I do not nessarily want to loop over it... is there a way
to do this?

If your <tr> has white space on each side, you could
use the ListValueCountNoCase( ) function (
http://livedocs.macromedia.com/coldfusion/5.0/CFML_Reference/Functions155.htm#1108281)
Use a space as the list delimiter.

How to count occurences of a certain string in incoming real-time data? Also displaying RTC data. Current VI included

I use LabView student Express 7 on a Windows XP system.
Time-frame: we are doing final integrations for our balloon experiment today. We just got told that the press wants to view real-time data, which we haven't programmed for. I need help to get a working VI at the latest by 25.02.2004 before 0800(morning) (GMT+1).
Note on license
It is a student balloon flight, and the data will not be used in scientific work, so the I am not breaking any license agreements (I hope).
Problem synopsis:
The balloon continually transmits data at 9600baud. The data is a semi-repeating header followed by a constant lenght data-package arranged like this:
BEXUS[h][m][s]BEXUS[h][m][s]
[Raw binary data, 7channels*8sub-channels*8bits]
What the groundstation is doing right now:
Take all incomming data and save (append) the data to a file without any data-handling. (We figured we would go post-processing).
What I need to change in less than 24 hours:
- Add a "package" counter
- Add a display of the clock data (RTC)
How I planned to implement the changes:
-RTC display:
The RTC data is in BCD format, since that means that if you look at the data as hex numbers, you get the hours and minutes and seconds out in "clear text". That is 12 hours is 0x12hex. I figured that I can do a match pattern BEXUS and pass the "after substring" to another match pattern BEXUS from which I feed the "before substring" to a type-cast VI (casting string to u8) and displaying that, which should give me a display of "123000" for the time 12:30:00... I couldn't get it to work at all when I tried out the supplied "beta" vi.
- Package counter:
Counting how many BEXUS that gets detected and dividing by 2. I don't know how to do this. I've looked on the forum (a good thread on the problem: "how do I count the number of *'s in a string") but these use either loops or arrays... and I'm not sure how this works when I'm getting the data in at realtime. I cant make an array and then count it, since then the array would grow fast and possibly interfere with saving of the data??? Saving the data is critical.. without that file we cant do post-processing.
Since my time is so limited (I'm not even supposed to do the groundstation software but they called on me in the last minute because no-one else had time/wanted too/could do it) I hope that you could make an exception and provide me with working VI's (based on the one I have attached) so that I can show something to the press! (Free comercial for NI!! Since the student version shows the National Instruments water-mark on all VI's!!! Possible TV time!!)
Thanks!
PS: even if you are to late (after 25) post anyway!
Why:
-I can learn from it
-the launch might be delayed due to weather conditions
-others might find it amusing!
Thanks again!

BexusII_groundstation.vi ‏46 KB

I have a valid example data file attached to this thread.
If you open BEXTEST.bin in a hex-editor of your choice, you'll see the BEXUS as 42 45 58 55 53 and then the time as 00 28 09 etc.
I couldn't get Joe Guo's VI to work. It doesn't count packages correctly, and the time is not displayed correctly either.
The file was saved using a straight save to file VI.
The data is from actual launching area tests performed a few mintues ago. The time displayed is "On time" e.g. how long the gondola has been powered up.
I have a spare T-junction, so I can hook into the balloon real-time data as we fly, in case anyone care to see if they can figure out why the latest version of Joe Guo's program is not displaying correctly.
I will monitor this
thread during and after flight to see if anyone can make it in time!
Thanks for the great effort!!

Count occurence of words in string

hi guys. i need some help.
my problem is. i have a string, and want to know how many times each word appears in it, and print out only the word that appear more than 2 times.
has any one an idea of how this is possible?

There are many solutions, but here is the outline of one possible method.
1) Split your string in words with the StringTokenizer class
2) Create a HashMap
3) look up your word in the hash map
4a) If the word is not in the hashmap, create a new entry in the HashMap, where the key is your word from the original string, and the Value is (new Integer(1))
4b) if the word is already in the hashmap, get the value from the hashmap, add one to it, then put the new Integer value in the hashmap
5) for each value in the hashmap, print out the key , if the value is an Integer > 1
With any luck, that will help you

String Count Occurence

i just want to count the number of occurence of character in string..
so i did this.. dont know whats wrong.. so someone help me
mport java.util.*;

public static void main(String[] args ) {
String input = args[0];
LinkedHashMap<Character, Integer> lhm = new LinkedHashMap<Character, Integer>();
for (int i =0; i<input.length(); i++) {
char currentChar = input.charAt(i);
if(lhm.containsKey(currentChar)) {
lhm.put(currentChar, lhm.get(currentChar) + 1);
} else {
lhm.put(currentChar, 1);
System.out.println(lhm.toString());

Counting occurences of a string (in a cell)

This is a little like the topic "Counting occurences of a word," except I want to be able to count how many times a specified search string occurs in a cell, not count how many cells contain the string. I would also like a formula that gave the offset of the starting character of the search string into the cell, such that a zero signified that the search string did not occur.
Basically, I want a general set of tools to parse a cell's string data, enabling me to determine where in the cell's string data each occurrence of another string is located & to extract parts of the string data relative to where the search string occurs.
For example, if the cell contains the string, "1ab2cd2e" I want to be able to extract "cd" & "e" based on the characteristic that they follow "2."

Here it is:
--(SCRIPT decoupeur.app]
Save the script as a Script, an Application or an Application Bundle named decoupeur
Put the file in the folder
<startup Volume>:Users:<yourAccount>:Library:Scripts:Applications:Numbers:
Maybe you would have to create the folder Numbers and even the folder Applications by yourself.
To use it,
Select the group of cells to convert
Copy to the clipboard
Select the destination cell
Goto Scripts > Numbers > decoupeur
You will be asked to define the separator to use.
Given the separator "2", the strings of the kind "1zer6sd2az2rt8aa2er7kkk5uu2a"
would be parsed and return az TAB rt TAB er TAB a
The converted values will be pasted at the cursor.

Counting occurences

Hello Experts,
I have the following query related to counting occurences of a particular characteristic related to the Calendar month
1) When I choose the option "Average of all values" within exception aggregation for the calculated keyfigure that I am using for the count, it counts all the values including duplicates .i.e. if the charcteristic has repeated occurences for a given month, then it is counted distinct occurence. However, in this case it is not showing me "0" for no occurence but just displaying a blank
2) But when I choose the option "Counting all values" within exception aggregation for the calculated keyfigure that I am using for the count, it does provides me "0" for no occurences but it counts the repeated value as single occurence
How can I get around this? I mean to get repeated values to be counted as separate occurences and also being able to show "0" for no occurence.
Any help will be appreciated
Thanks,
Rishi

Hi ,
Please use exception aggregation as you already did with count all values.
But you need to select a specific reference chars to select the unique count.Plant or the Month can be a option.
In BI7.0 U have concept of nested aggregation:
Create a CKF1 with reference to one Char. and craete another CKF2 using the earlier CKF1 and put again a reference on some other char.
that will solve the problem.
Please take care of the selection of Char while doing reference char.

Counting occurence in image

I don't know nothing about NI image DAQ, I'm new to this, I'm a Labwindows/CVI programmer and recently a client asked me if its possible to count cells occurences in an image. Before investing money in such system (seems to be very expensive) I would like to know if NI VISION functions are powerfull enough to count occurences of a human cell in an image ?
Thank you,

The short answer to your question is yes and there are similar examples on the IMAQ Vision demonstration CD. I would suggest you try and organize a demo from your local NI office.
Application Note 107 gives a good tutorial on this topic and you can get access to it at the following link:
http://zone.ni.com/devzone/conceptd.nsf/webmain/1D977AE5ED42CB0C86256869007215CC?opendocument&node=DZ52495_US
As far as support for LabWindows/CVI is concerned, you may see a lot more "traffic" regarding LabVIEW on Developer Zone, but rest assured the capability of the CVI version of IMAQ Vision is virtually identical and there should be enough help either direct from NI or through Developer Zone to help with your application.
With regards to questions about cost, t
he cost of the application will have to be considered versus the benefits of introducing an autonomous inspection system. Your customer may find that the increases in throughput i.e. number of samples/images per hour that can be inspected or the reliability of the results produced (most people will strive towards a 100% inspection imaging application) will offset the initial development costs. This is particularly true if your customer is currently manually inspecting the samples (for example under a microscope).

Read Text file and count occurences of certain string

Hello,
I have a text file with lines of data in it. I would like to read this text file and count how many lines match a certain string of text.
For example my text file has this data in it.
dog,blue,big
dog,red,small
dog,blue,big
cat,blue,big
If the certain string of text is "dog,blue,big" then the count would return "2".
Thanks for your help

Getting count of occurances of a string in a column value

Hi,
Is there a way to get the number of occurences of a string in a single column value?
Example:
CREATE TABLE STRING_CNT(X VARCHAR2(100));
INSERT INTO STRING_CNT(X) VALUES('OracleXXOracleXXOracleXXOracle');
Commit;
Now the string 'Oracle' is repeated 4 times in the inserted value. I would like to get this count using SQL.Can some one tell me how to get this?
I was asked this interesting question in an interview today.

hi 
u can get the occurrence of a string in text as
follow 
>
SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) 
/ LENGTH('Oracle') as 
Occurrence FROM STRING_CNT; 
 
Are you sure...? 
 
 
SQL> with STRING_CNT as
2 (select '1.Oracle2.Oracle3.' x
3 from dual)
4 SELECT (LENGTH(x)-LENGTH(REPLACE(x,'Oracle', ' ' ))) / LENGTH('Oracle') as Occurrence
5 FROM STRING_CNT;
OCCURRENCE
1.66666667
 
Sidenote: Please give a try before posting.. 
And you are posting a wrong solution after a TESTED right solution posted hours before..

Count a character within a string

Give a string, what function can I use to count how many a particular character in the string. For example:
"abc;def;ghi;xyz"
I want to find out how many ";" in this string.
Thank you

And of course, if the researched character is not in the given string, then you'll return null, to return 0, you'll need a NVL.even if it is in the string you might need a nvl in Vamsi Kasina's solution:
SQL> select length (';') - length (replace (';', ';')) cnts
from dual
      CNTS
1 row selected.Better:
SQL> select nvl(length (';'),0) - nvl(length (replace (';', ';')),0) cnts
from dual
      CNTS
         1

You need to modify the algorithm slighty in order to work correctly when the string consists only of the search pattern.
