Find number within string

Hi guys/gals,
Im looking to be able to find a number (any number) within a text string, what i ultimately want to do is crop the number out of the string to just be left with a number value, the only problem is the string could be any length and the number doesnt necessarily start at any point from the last character
I have items on the stage named 'image0', 'textfield2', 'button500' etc, as you can see the prefix before the number isnt a fixed length so I couldnt use substr and set an index, and since the number could be any number i couldnt set the index as a certain value before the end of the string. (ie it might return '500' or 'ld2' or 'ge0' in the examples given before)
I was looking into how to use IndexOf, but I dont really know how to make it so that it finds any number rather than a specific one
can anyone help me out?
Thanks

One way to do this is by using regular expressions. In the example below, the str string has anything that is not a number removed.
var str:String = "button500";
var regex:RegExp = /\D/g; // matches anything that is not a digit
var numStr:String = str.replace(regex, "");
trace(numStr);

Help with finding digits within string

Hi, I am very close (I believe) to finishing this program. Basically I need to scan the input (string) the user enters. If the input contains 2 digits then I outprint "Valid ID" if not, I outprint "Invalid ID"
please review and if possible help fix it?
Thank you.
import java.util.Scanner;
public class programTest
     public static void main(String[] args)
d     {
     String id;//id entered by user
     Scanner kb=new Scanner(System.in);//scanner utility
          System.out.println("Please enter an ID: ");
          id=kb.next();//assigns user's id to variable id
          if (id.length()>=2 && id.length()<=9)
                  for (int i=0; i<id.length(); i++)
                    if(Character.isDigit(id.charAt(i)))//if id contains 2 digits
                    System.out.println(i);
                    System.out.println("Valid ID");
          }

Finally! After sitting down for a few minutes and watching the show House I thought of a way to do it.
I am almost POSITIVE there is a simpler way to do this, so if you have it please repost the more "efficient" way.
Thank you very much for everyone's help!
import java.util.Scanner;
public class Test
     public static void main(String[] args)
     String id;//id entered by user
     Scanner kb=new Scanner(System.in);//scanner utility
     int digit=0;
          System.out.println("Please enter an ID: ");
          id=kb.next();//assigns user's id to variable id
          if (id.length()>=2 && id.length()<=9)
          {//if
                  for (int i=0; i<id.length(); i++)
                         if(Character.isDigit(id.charAt(i)))
                         digit++;
                         if (digit!=2)
                         System.out.println("Invalid ID");
          }//if
          else
               {     System.out.println("Invalid ID");     }
          if (digit==2)
          System.out.println("Valid ID");

To find substr within string

Hello,
I have a string (column is normal range) like 70 - 110 mg/dl.
I wanted to separate 70 and 110.
For 70 i am using like this
select substr(normal_range,1,instr(normal_range,'-')-1) from m_parameters where normal_range='70-110 mg/dL'. It works.
But how to get 110.
Some rows may also be 110-209 U/L without any space between '-'.I want a query which works for all conditions.
Conditions are.
1. 70 - 110 mg/dL
2. 70-110mg/dL
3. 70 -110mg/dL
4. 70- 110mg/dL
5. 70-110 mg/dL
thanks

Trying to determine the last occurence of a number within a word string.

Hi All,
I am trying to find the last occurence of a number within a string. I have had a quick look at the Java Tutorial and know about lastIndexOf and substring. The thing is I have to test for the existance of the numbers 0-9 within a product code that typically looks like this:
s1_14G12B
s1_17G1BA
s2_24GD
The only part of the above strings that I am interested in is the letter(s) that follow the very last number, so in the case of those codes presented above, I would like to extract the following:
B
BA
D
I have written some code that performs a similar operation:
public class FindPriceCode
private String priceCode;
private String[] numberValues = {"0", "1", "2", "3", "4", "5", "6", "7", "8", "9"};
public FindPriceCode()
    priceCode = "s2_71G4BA";
    for(int i=0; i<numberValues.length; i++)
      int location = priceCode.lastIndexOf(numberValues);
System.out.println("Character " + numberValues[i] + " found at position: " + location);
public static void main(String[] args)
FindPriceCode myPriceCode = new FindPriceCode();
...finding the location of numberValues string within the given example code. I am now at a loss as to how I can determine the location of the last number occurence (moving right to left) and then build a substring from that number. Any help will be greatly appreicated.
Thanks
David

You can do like this.
The below mentioned is code separate material
    DO 18 TIMES.
      LV_C = LV_C + 1.
      LV_C1 = LV_C - 1.
      IF GW_MATNR-MATNR+LV_C1(1) CN '0,1,2,3,4,5,6,7,8,9' .
        IF ( ( LV_MAT EQ SPACE ) ) ." and ( lv_prefix eq space ) ) .
          LV_PREFIX = 'X'.
          CONCATENATE GW_TEMP-PREFIX GW_MATNR-MATNR+LV_C1(1) INTO
          GW_TEMP-PREFIX.
        ELSE.

How can I find out the strings that will be presented to the UI

Hi All,
I am working on a Swing based application (Swing based UI)
I am requested to do the following on the bytecode of that application:
I am supposed to find out what strings from within that bytecode will be presented to the UI and what will be used for an internal usage.
i have no way of running the application to verify that, i can only work on the static bytecode files.
hard question ha?
Thanks,
EItan.

You would of course have to run it. Either via a VM or recreating a VM yourself.
As an example of that how would you figure out what string occurs in the following (pseudo) code?
String msg = (cnt > 1) ? ("files=" + cnt) : ("file=" + cnt);
if (cnt > 1) DisplayMessage(msg);

I think you will find it much easier if you had an array of clusters. The array can be sized however big you need it. On the block diagram, use a for loop to index through the array a perform whatever actions you want on it. You may also look at event structures to control the read and write.
Look through the help files. They are very complete and the examples offer some good ideas.

Find number of occurances of a particular character

Hi,
is there any keyword to determine number of times a particular character is present in the string,
E.g. VAR1 = 'ghghj#ghjgjgh#ghjghjg#ghjg#'.
I want to find number of occurances of # in VAR1.
Regards,
Raghavendra

Hi,
       use folowing logic.
       data:begin 0f itab,
                var1 type c,
                 var2 type c,
                 var3 type c,
                  var4 type c,
              end of itab.
split var1 at '#' into itab-var1 itab-var2 itab-var3 itab-var4.
    if not itab-var1 is initial.
        count = count + 1.
    endif.
       if not itab-var2is initial.
        count = count + 1.
    endif.
    if not itab-var3is initial.
        count = count + 1.
    endif.
    if not itab-var4is initial.
        count = count + 1.
    endif.
write count.

Oracle Spatial function to find nearest line string based on lat/long

Hi,
Here is my scenario. I have a table that contains geometries of type line strings (the roadway network). The line geomteries are of type Ohio state plane south (SRID 41104).
I have a requirement - given a lat/long, find the line string that snaps to that lat/long or the nearest set of line strings within a distance of 0.02 miles.
This is a typical example of trying to identify a crash location on our roadway network. The crashes being reported to us in lat/long thru the GPS system.
How can i acheive this through any spatial functions?
Thanks for the help in advance.
thanx,
L.

Hi L,
That is not the way I would do it. I would convert my road segments to LRS data, then you can do all queries on the same data.
Or, if you do not want to modify your original data, create a copy of your road segments with the same ID's and convert the copy into LRS data. If you keep the ID's identical, you can easily use geometry from one and LRS data from the other - as long as you are sure the ID is the same.
Which will make the workflow a bit easier:
1. Use SDO_NN to get the closest segments
2. Use SDO_LRS.PROJECT_PT to get the projected point
3. Use SDO_LRS.GET_MEASURE to get the measure
And most of these you can incorporate into one single query. Now I am writing this of the top of my head (It's been a while since I played with LRS). so this has not been tested, but something like this should work (but could probably be greatly improved - it's getting late for me :-) ):
SELECT
SDO_LRS.FIND_MEASURE --//find_measure needs an LRS segment and a point
    SELECT            --//here we select the LRS segment
      r.geometry
    FROM
      roadsegments r
    WHERE SDO_NN(r.geometry,    --//based on the given GPS point
                 sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                 'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
SDO_LRS.PROJECT_PT --//We project the point on the LRS segment
      SELECT         --//here we select the LRS segment (again, which could probably be improved!!)
        r.geometry
      FROM
        roadsegments r
      WHERE SDO_NN(r.geometry,
                   sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL),
                   'sdo_num_res=2 distance=0.02 unit=mile') = 'TRUE'
    sdo_geometry(2001, 41104, sdo_point_type(lat,lon,NULL), NULL, NULL) --//The GPS point again
AS milemarker from dual;So it is not as complicated as you think, it can easily be done with just one query (SQL can do a lot more than you think ;-) ).
Good luck,
Stefan

Autocreate item number within a number range

A newbie question:
Can SBO auto generate an item number when the user adds a new item via the Item Master Data screen? Is it possible to define this number within a number range?

As Harold says, with formatted search you can do many nice things...
Also take a look at the <a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/tsqlref/ts_aa-az_3ied.asp">Trans-SQL reference</a> (if you are using SQL server as a database server), here you can find loads of information about the Trans-SQL language of SQL server...

Index-within-string

I have an xml string and there's a tag called </ErrorDescription>, I want to find where in the string does this tag begins. I used
oraext:index-within-string(<inputstring>,'</ErrorDescription>') but I got the xpath error. I think it's because of the slash character (/).
How do I escape it please?

Hi,
First try getting the xml as string using ora:getContentAsString and then use above function.
