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 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%>

How can I write this string to a file as the ASCII representation in Hex format?

I need to convert a number ( say 16000 ) to Hex string ( say 803E = 16,000) and send it using Visa Serial with the string control in Hex Mode. I have no problem with the conversion (see attached). My full command in the hex display must read AA00 2380 3E...
I can easily get the string together when in Normal mode to read AA0023803E... but how can I get this to hex mode without converting? (i.e. 4141 3030 3233 3830 3345 3030 3030 3031 )

Sorry, The little endian option was probably introduced in 8.0 (?).
In this special case it's simple, just reverse the string before concatenating with the rest.
It should be in the string palette, probably under "additional string functions".
(note that this only works in this special case flattening a single number as we do here. If the stat structure is more complex (array, cluster, etc.) you would need to do a bit more work.
Actually, you might just use typecast as follows. Same difference.
I only used the flatten operation because of the little endian option in my version.

How can I parse this date format?

Hey,
i am trying to write an interface between two applications. One application gives me the following date:
Wed Jul 16 12:18:20 CEST 2003
but I need it to look like this:
16.07.03 12.18:20
I tryed to use Date and DateFormat to parse and change it but the Date was unparseable.
I hope somebody can point me to the right direction or show me how I can do the formating.
Thanx a lot!
Martin

If this isn't a well-known date format, I can't see any solution but to write small function yourself which doe the job.
you can start with :
String source = "Wed Jul 16 12:18:20 CEST 2003";
String[] elements = source.split();//splits source around spaces
then you write functions that map day of week with numbers
"Mon" --> 1
"Tue" --> 2
etc...
it won't take you days to write this.
Sometimes it's faster to write the stuff yourself than spending days looking for something pre-defined that may or may not exist.

How do you convert this String into a double?

Hi, in this code I want to convert String arg into a double. I'm trying to do this so that I can convert some string into a double in this calculator that I'm making. Here is the code:
public class par {
public static void main(String[] args) {
String str = "351";
double arg = new double(str); // should convert the string into a double
System.out.println(arg);
System.out.println(str);
I keep getting errors in line 4, if any of you could help me out here I'll be thankful, i'm kinda new to java and my search for java's equivalent of alof() (its a function in C libraries that converts char[] into a double)lead me to this.

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);

A database version would help us providing you with a relevant solution.
Starting with 10g, you can do :

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 *
