How do i parse a string

Can somebody tell me the function used to parse a string and how it works? All I want to do is seperate the string 'AG-01' into another string 'AG-' and an int '01'. I have been through numerous resources and have found nothing at all on parsing functions.

This in one way:
String txt = "AG-01";
String first = txt.substring(0,3);
int second = Integer.parseInt(txt.substring(3,5));
%>
First string:<%=first%>
Second int :<%=second%>
Bye

How can I parse a String to Timestamp type??

Hi, I receive a String time="07.05.2007 12:30:20", I want to parse this String to a Timestamp type, how to do that?

I use the following code to parse String to Date, but it throw unhandled exception, type parse exception. It seems the parse source "07.05.2007 12:30:10" has problem.
SimpleDateFormat sdfTest=new SimpleDateFormat("dd.mm.YYYY HH:mm:ss");
Date newDate=sdfTest.parse("07.05.2007 12:30:10");
Please give me some suggestion.

How do I parse this string?

I have a string of html , which looks like this:
<head></head><body>Stringoftagsinhtml
I have to go ahead a search for the tags and put them into a tree.
for instance.
<head> would be the root, then I would go to and get the contents thereof, where and would be child nodes.
I am not sure how to look throw a string and search for these things. can anyone suggest a good way of doing this?
Originally I was thinking of going through it like an array, but apparently that is illegal.
Thanks.

You're throwing away the first line of the file.
This line of code:
 String line = in.readLine();reads in the first line, but then you ignore what's in line.
You should change it to just:
 String line;Similarly, you're throwing away alternate lines of input with this line of code:
 line = in.readLine();You should just remove that.
[add] ...you're too fast for me

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

How can I parser a String with javax.xml.parsers.DocumentBuilder?

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.

Parse a String to boolean

How do you parse a String to boolean, isn't like this? I get this inconertible types error, that require boolean
boolean all = (boolean)tokens.nextToken();
Thanks!

What string means true, and what string means false? The string "true" or "false"? In that case, you can simply use the Boolean.valueOf(String) method:
public static Boolean valueOf(String s)
    Returns a Boolean with a value represented by the specified String. The Boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
    Example: Boolean.valueOf("True") returns true.
    Example: Boolean.valueOf("yes") returns false.
    Parameters:
        s - a string.
    Returns:
        the Boolean value represented by the string.Otherwise, you can use something like:
boolean b = string.equals("true");or if string can be null to also mean false:
boolean b = "true".equals(string);

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.

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.

How could i parse string and link its model with my files in eclipse project?

How could i parse string and link its model with my files in eclipse project?, as i read that we dont have to use standalone mode while working with eclipse projects.
Example of what i want to do:
I have file1.dsl in my project which contains some statements but the declaration of these statements are not in another file, i need to put them only in my code

Hi Stefan,
I have eclipse project contains 2 files, file1.dsl and file2.dsl, you can see the contents of the files below.
file1.dsl contains some statements as shown below and file2.dsl contains the declarations of the variables. (like in C++ or Java we have declarations and usage)
At this step file1.dsl and file2.dsl will be parsed successfully without any errors.
Lets imagine that we will delete this project and will create another one and the new project will contain only file1.dsl (which contains the usage)
At this step this file (file1.dsl) will contains some errors after parsing it, because we are using variables without declarations.
So what i need is to parse the content of file2.dsl directly without adding this file to the project.
I need to add the content of file2.dsl directly as a string in the code and parse it. just like that ( "int a;int b;" )
And link file1.dsl with the model generated after parsing my string
file1.dsl
a++;
b++;
file2.dsl
int a;
int b;
Thanks

How to Parse a string into an XML DOM ?

I want to parse a String into an XML DOM. Not able to locate any parser which supports that. Any pointers to this?

Download Xerces from xml.apache.org. Place the relevant JAR's on your classpath. Here is sample code to get a DOM document reference.

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

Thanks again for your help. This is what I ended up doing:

How to parse a String help

I'm trying to find an easy way to parse a string like this
String, brand,model, number;
String toParse=(Sony)(VZ-12324)(1);Is there a simple way of parsing the string to the "(" and ")" are omitted and brand=Sony;
model=VZ-12324);
number="1";
???

String toParse = "(Sony)(VZ-12324)(1)";
String[] parts = toParse.split("[()]");
String brand = parts[1];
String model = parts[3];
int number = Integer.parseInt(parts[5]);
System.out.println(brand);
System.out.println(model);

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);
}
