Parsing an string by occurances of "-", and an expert opinion of alternative

Hi Everyone I have a drop down with this format data:
"001-9122-349-0000-000000-001-00-000"
Need the data be parsed at "-" occurrence, which essentially breaks into 8 parts, and then populated into individual text fields!
Does anyone have a script to do this? or a suggestion to do it smarter?

If the fields are named something like Text1 to Text8 you can use this code as the field's custom validation script (make sure you tick the option to commit the selected value immediately):
var v = event.value.split("-");
for (var i=1; i<=8; i++)
this.getField("Text"+i).value = v[i];

Parse a String with FIRSTNAME MI and LASTNAME but not always a MI

Anyone,
can I write a single clause to parse a column that cotains first name, middle initial and Last name but the Middle initial is sometimes there and sometimes not?
Like this:
Steven F Abbott
Mikel Allums (Steve)
Pedro A Arroyo
Daniel R. Hasbrook
Steve G Ball
Ernie C Bloecher
Richard Carrillo
James M Chamberlain
I need data seperated.
I have:
SUBSTR(NAME, 1, (INSTR(NAME,' ',1,1)-1)) "FIRST_NAME",
SUBSTR(NAME,(INSTR(NAME,' ',1,1)+1), LENGTH(NAME)) "LAST_NAME",
But that middle initial presents problems and I see it as first letter in last name but if I chnage the search for space to second occurance I get the whole name:
SUBSTR(NAME,(INSTR(NAME,' ',1,2)+1), LENGTH(NAME)) "LAST_NAME",
Any help would be greatly appreciated.
Thanks,
Miller

may this eaxmple is little better if there is only one name then will display as first anem only

Parsing a string in PL/SQL?

I am parsing a string in PL/SQL and at a certain point(Length 45) of the string I would like to add a carriage return (Chr(10)), then continue with the string at that point and then again if the string is greater than Length 45 add a carriage return.
I program in Powerbuilder and have figured it out, but I have a problem when trying to add a carriage return at a certain point in the string in PL/SQL. There is the REPLACE(), but that will replace everything, but I only want to add it at that certain point of the string. With the PB function I can add the carriage return at a certain point, see code:
Li_pos = PosA( Ps_data, '*')
DO WHILE Li_pos > 0
ll_length = Li_pos - ll_old_pos
IF ll_length > 45 THEN
ll_old_pos = Li_pos
Ps_data = ReplaceA( Ps_data, Li_Pos, 1, ls_carriage_rtn) **This function gives me the ability to add a carriage return at a certain point in the string. **
Li_pos = PosA( Ps_data, '*', Li_pos + 1 + ls_carriage_rtn)
ELSE
Li_pos = PosA( Ps_data, '*', Li_pos + 1)
END IF
LOOP
I have incorporated the same logic in PL/SQL but I am looking for something similar to the ReplaceA function in PB, that will replace at a certain point in a string. I use an '*' as a placeholder and measure the length. Below is the PL/SQL code:
t_pos NUMBER;
t_old_pos NUMBER;
t_length NUMBER;
BEGIN
t_old_pos := 0;
t_pos := INSTR(in_model_list, '*');
WHILE t_pos > 0 LOOP
t_length := t_pos - t_old_pos; -- This looks at current position minus the old position, measures the length
IF t_length > 45 THEN
t_old_pos := t_pos;
*** add that carriage return
t_pos := INSTR(in_model_list, '*', t_pos + 1 + Chr(10)); -- get the new position
NULL;
ELSE
t_pos := INSTR(in_model_list, '*', t_pos + 1);
END IF;
NULL;
END LOOP;
Here is the data, what it looks like: William 112,* 500-A,* 500-U,* 520,* 560-A,* 560-E,* 680-E,* 680-F,* 680-V*
Any help would be much appreciated.
Thank you,
William

Question on parsing a string and storing it, help!

im doing a assignment and a part of it requires getting a string from the user and storing it.
for example:
string given was "a / b , c / d"
the only data i would store into my array would be the chars but the length is not always given which means it can be a / b or longer. is there any way i can parse it while ignoring the whitespaces. so the array after being parsed is
arrayOfChars[0] = a
arrayOfChars[1] = b
arrayOfChars[2] = c
arrayOfChars[3] = d
any sugguestions on how i would parse a string that will be separated by symbols such as / , ! * ? i was told there was a split() that would do the job or the string tokenizer which was what i woulve used.
THANKS IN ADVANCE!

only letters would be found. just run the following code (fixed some typos as well...):
String myString = "a , 1";
StringBuffer sb = new StringBuffer ();
for (int i=0; i<myString.length(); i++) {
if (Character.isLetter(myString.charAt(i))) sb.append(myString.charAt(i));
System.out.println(sb.toString());the result will be "a". if you want digits to be found too, you must check for Character.isDigit() as well...

Parsing a string in a sproc

I have a Java class that calls a stored proc and passes a stringbuffer object to it. The sproc should parse the string to retrieve the different ids that are concatenated in the stringbuffer and for each id retrieve a row from a table and in the end return a cursor containing the returned rows.Can anyone help me out with the parsing logic for a pipe delimited string.

This might help you. If you want to handle the cursor in java, then convert the below into a function which returns the cursor.

Anyone know how I can parse this string?

Hello everyone!
I'm using the Scanner class (which is like the StringTokenizer class but suppose to be more powerful).
Anyways, I have the following String:
OP '1.3.12.2.1004.212'.'1.3.12.2.1004.195'
I want to parse the String so I have the following:
'1.3.12.2.1004.212'
'1.3.12.2.1004.195'
so basically just parse it by the middle dot, I tried useDelimeter function and it doesn't parse it up at all. You would think it would have parsed every occurance of . but that isn't the case.
Here is my code:
else if(line.contains("OP"))
                         System.out.println("HIT THE SUBFIELD PART lulz");
                         String subClassName = "";
                         String subFieldName = "";
                         scan = new Scanner(line);
                         scan.useDelimiter(".");
                         System.out.println("LINE: " + line);
                         while(scan.hasNext())
                              System.out.println("Token: " + scan.next());
                         }The output is the following:
HIT THE SUBFIELD PART LOL
LINE: OP '1.3.12.2.1004.212'.'iPAddress'
Token:
Token:
Token:
Token:
Token:
Token:
Token:
Any ideas what I can do to parse it up the way I mentioned above? thanks!

hm..it just occured to me I could do the following
else if(line.contains("OP"))
                         System.out.println("HIT THE SUBFIELD PART lulz");
                         String subClassName = "";
                         String subFieldName = "";
                         scan = new Scanner(line);
                         scan.skip("OP");
                         scan.useDelimiter("'.'");
                         System.out.println("LINE: " + line);
                         while(scan.hasNext())
                              System.out.println("LOOK HERE: " + scan.next());
                         }I get the following output:
LINE: OP '1.3.12.2.1004.212'.'iPAddress'
LOOK HERE: '1.3.12.2.1004.212
LOOK HERE: iPAddress'
So I guess I can just manually manipulate that last token and readd the ' character!
I think thats what I will do but if you can find a bettter solution let me know! thanks! :D

Parsing a string using StringTokenizer

Hi,
I want to parse a string such as
String input = ab{cd}:"abc""de"{
and the extracted tokens should be as follows
ab
cd
"abc""de"
As a result, I used the StringTokenizer class with deilmeter {,},:
StringTokenizer tokenizer = new StringTokenizer(input,"{}:", true);
In this was, I can separate the tokens and also can get the delimeters. The problem is I don't know how to parse the string that has double quote on it. If a single quote " is taken as a delimeter then
", abc, ",", de," all of them will be taken as a separate token. My intention is to get the whole string inside the double quote as a token including the quotes on it. Moreover, if there is any escape character "", it should be also included in the token. Help please.
Thanks

A bit of a "sticky tape"-solution...
import java.util.StringTokenizer;
public class Test {
    public static void main(String[] args) {
        String input = "ab{cd}:\"abc\"\"de\"";
        StringTokenizer st = new StringTokenizer(input, "{}:", true);
        while(st.hasMoreTokens()) {
        String token = st.nextToken();
        if(token.startsWith("\"") && token.endsWith("\"")) {
        token = token.substring(1,token.length()-1);
            System.out.println(token);
}

Parsing formatted String to Int

How can I parse formatted string to Integer ?
I have a formated string like this $900,000 and I need to convert it to 900000 so I could do calculations with it.
I tried something like this
NumberFormat nf = NumberFormat.getIntegerInstance(request.getLocale());
ttlMargin=nf.parse(screenVal);I got this exception
"java.lang.NumberFormatException: For input string: "$1,050,000""

I am working on the JSP file that provides
margins,sales etc. I am reading this data off the
screen where it is beeing displayed according to the
accounting practices.
That's why I get it as a formatted string and why I
am trying covert that string to the numberScreen-scraping is a problematic, bad design. It sounds like what you really want is to call a web service which returns its results as data that a program can understand (XML, for example), not HTML (which is meant more for humans to read). I know, you probably can't change the design at this point... just food for thought. In the meantime, you'll probably have to manually parse those strings yourself by stripping out the '$' and ',' characters and then use parseInt on the result.

How to parse a string containing xml data

Hi,
Is it possible to parse a string containing xml data into a array list?
my string contains xml data as <blood_group>
     <choice id ='1' value='A +ve'/>
     <choice id ='2' value='B +ve'/>
         <choice id ='3' value='O +ve'/>
</blood_group>how can i get "value" into array list?

There are lot of Java XML parsing API's available, e.g. JAXP, DOM4J, JXPath, etc.
Of course you can also write it yourself. Look which methods the String API offers you, e.g. substring and *indexOf.

Passing / parsing XML String IN / OUT from PL / SQL package

Hello, People !
I am wondering where can I find exact info (with code sample) about following :
We use Oracle 8.1.6 and 8.1.7. I need to pass an XML String (could be from VARCHAR2 to CLOB) from VB 6.0 to PL/SQL package. Then I need to use built in PL/SQL XML parser to parse given string (could be large hierarchy of nodes)
and the return some kind of cursor thru I can loop and insert data into
different db Tables. (The return value may have complex parent/child data relationship - so I am not sure If this should be a cursor)
I looked online many site for related info - can't find what I am looking
for - seems like should be a common question.
Thanx a lot !

How to parse a string in CVP 7.0(1). Is there a built-in java class, other?

Hi,
I need to parse,in CVP 7.0(1), the BAAccountNumber variable passed by the ICM dialer. Is there a built-in java class or other function that would help me do this?
Our BAAccountNumber variable looks something like this: 321|XXX12345678|1901|M. In IP IVR I use the "Get ICM Data" object to read the BAAccountNumber variable from ICM and then I use the "token index" feature to parse the variable (picture below).
Alternately, IP IVR also has a Java class that allows me to do this; the class is "java.lang.String" and the method is "public int indexOf(String,int)"
Is there something equivalent in CVP 7.0(1)?
thanks

Date contructor deprecation : Parsing a String to Date

Hi All,
In Java 1.5 the Date() constructor Date(String s) is deprecated. As per the API Documentation DateFormat.Parse() method is used.
The following code from Java 1.4 version has to be upgraded to Java 1.5.
Existing Code:
Date dDate = new Date(sDate);
Modified Code:
DateFormat df = DateFormat.getDateInstance();
Date dDate = df.parse(sDate);
Here the DateFormat accepts a default formatting style as "Feb 01, 2007" and parses the String.
If the String sDate belongs to any other formatting style such as "01 Feb, 2007" or "01 Feb, 07" the code piece throws unparsable date error.
Please give your thougts on this issue to parse the string of any format..
Thanks,
Rajesh.

Parsing a string to integer gives 0 in Integer

Hi ,
try
usid = Integer.valueOf(usi).intValue();
catch(NumberFormatException e)
text = "NUMber";
in the above code the value of usi is 4
then parsing it is giving me 0 in usid
try
usid = Integer.parseInt(usi);
catch(NumberFormatException e)
text = "NUMber";
I also tried the above code the result is same

Also the OP didn't say which version of JDK he was using.
With JavaSE5 and JavaSE6 , there's a new feature called autoboxing , which eliminates the need to cast from a String to an Integer , and then to get an int value .
Insead one could simply write code like this and i works:
Integer someInteger = 123;
int anInt = 555;
someInteger = anInt;
anInt = someInteger;Autoboxing and Autounboxing : http://java.sun.com/j2se/1.5.0/docs/guide/language/autoboxing.html
But the article further adds:
So when should you use autoboxing and unboxing? Use them only when there is an �impedance mismatch� between reference types and primitives, for example, when you have to put numerical values into a collection. It is not appropriate to use autoboxing and unboxing for scientific computing, or other performance-sensitive numerical code. An Integer is not a substitute for an int; autoboxing and unboxing blur the distinction between primitive types and reference types, but they do not eliminate it.

Parsing a string in a given order

Hi All,
I want to parse a string and rank it in a given order.
Eg : i have a string as 'A | B | C | D'. I would like to parse this string and give a rank in order.
It should appear as below.
Parsed string order
D 1
C 2
B 3
A 4
Any help is greatly appreciated..

A database version would help us providing you with a relevant solution.
Starting with 10g, you can do :
SQL> var my_str varchar2(30)
SQL> exec :my_str := 'A|B|C|D'
PL/SQL procedure successfully completed
SQL> select item
2       , row_number() over(order by item desc) as rank
3 from (
4    select regexp_substr(:my_str,'[^|]+',1,level) as item
5    from dual
6    connect by level <= length(regexp_replace(:my_str,'[^|]+')) + 1
7 );
ITEM                    RANK
D                          1
C                          2
B                          3
A                          4
In 11.2 :
SQL> select *
2 from xmltable(
3       'for $i in ora:tokenize($str,"\|") order by $i descending return $i'
4       passing 'A|B|C|D' as "str"
5       columns item varchar2(10) path '.'
6             , rank for ordinality
7       )
8 ;
ITEM             RANK
D                   1
C                   2
B                   3
A                   4
