Parse a string to remove character

Hi,
Can you please help. I have a string like "1a" or "12c". Is there a way I can parse this to remove the character values, leaving "1" and "12"
Many Thanks

By using
[url=http://java.sun.com/j2se/1.4.2/docs/api/java/lang
/String.html#replaceAll(java.lang.String,
java.lang.String)]String.replaceAll(String regex,
String replacement)To remove all non-digit
characters:replaceAll("\\D+", "");Or to remove all
letters:replaceAll("\\p{L}+",
"")(Check
[url=http://java.sun.com/j2se/1.4.2/docs/api/java/util
/regex/Pattern.html]Pattern doc if you want to
refine it.)
Also, you should note that String.replaceAll does not modify the Original string, it returns a NEW string with the modified value. A string is technically immutable.
so you want the code to be something like:
String cleanString = String.replaceAll( whichever pattern you choose );

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);
}

Problems parsing a string

Hi,
I'm having a problem with parsing a string. Basically, I want to take a string for example: "TomWentToTheShop" and divide it into a coherent sentence (Tom went to the shop).
I've started the code by breaking the string into a char array, and if the character is a capital then store the index in the array and then do a substring.
But I don't think this is the best way to solve the problem, if anyone has any ideas it would be greatly appreciated.
thanks.
char[] charRequestTypeArray = string.toCharArray();
for (int i = 1; i < (charRequestTypeArray.length -1); i++) {
char c = charRequestTypeArray;
if (Character.isUpperCase(c)) {
Arrays.fill(storeCapitalIndex, i);
else{
Arrays.fill(storeNonCapitalIndex, i);

String s = "TomWentToTheShop";
System.out.println(s.charAt(0) + s.substring(1).replaceAll("((?<!^)[A-Z])", " $1").toLowerCase());or even just System.out.println(s.charAt(0) + s.substring(1).replaceAll("([A-Z])", " $1").toLowerCase());Edited by: sabre150 on Nov 11, 2007 9:40 PM

Parse a string that uses nested string delimiters

I’m looking for a way to parse a string that uses double quotes as the delimiter that contains a nested string with double quotes. I want to keep the double quotes in the nested string. Is there a function in Labview that I can use to easily do this? Does Labview have a command line parser / interpreter?
The string example is: While match "Send Test "Sleep 5" ">""
The result string would be: Send Test "Sleep 5" ">"

Here is another solution which is slightly faster. Speed won't be
an issue unless you are running millions at a time, as in my test the
difference was only 1-2 ms in 10000 iterations. In this image the
Match Pattern function retrieves the desired string, including the
outside quotes, so the String Length and String Subset functions are
used to remove the first and last characters of the result.

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

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 hex strings

Hi
How do I parse a string that is in hex format
e.g. Integer.parseInt("0xff");
It keeps throwing a numberformatexception
Thanks
John Cleary.

If you read the API for that method, you'll see, "The characters in the string must all be decimal digits, except that the first character may be an ASCII minus sign."
Try either parseInt that takes a radix or java.text.NumberFormat.

I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

I would like to do a program that have one string control and one string indicator, any character that I type in the string control in the same time it will be appear in another string (indicator). How can help me?

Why not use an event
Add a While Loop, inside the loop add the Event Sructure.
Now in the event structure selecd the String Controls.value change event to
react
and the new value inside the event that you get,( connect to the String
indicator box.

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 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.
