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

Is there a problem on the pattern of SimpleDateFormat to parse a String ?

Hello,
I tried to parse a String to a Date using a SimpleDateFormat.
I must be able to have on the pattern something like : "yyyyMMdd_HH00".
To get a String from a Date with SimpleDateFormat.format(Date date) it works well, but when a try to parse a String into a Date with SimpleDateFormat.parse(String date) I get a : java.text.ParseException: Unparseable date.
I try it on a JVM 1.4 and 1.5 for the same result.
An exemple of code :
          String pattern = "yyyyMMdd_HH00";
          SimpleDateFormat currentFormat = new SimpleDateFormat(pattern);
          Date date = currentFormat.parse("20091223_1000");It seems that adding the '00' after 'HH' raise the exception...
Has the 'HH00' a particular meaning like on Oracle 'HH24' ?
Is there a way to add number after the 'HH' ?
Thanks
Edit :
Oh yeah, I forgot, I tryied to use the pattern "yyyyMMdd_HH'00'" using '' to escape the 00 without better result...
Edited by: Jeremy.Antonucci on 23 déc. 2009 15:25

The context of this pattern :
To get a file on a http server, I must build an Url String with a filename using the current date.
I want to be able to change easily the pattern on a file parameters.
The date must be ending with 00 for the minutes.
I may have use a pattern with 'HHmm' and suppress the minutes but if it is change on the futur the code will not work...
As I can't say if in the futur the url will change for the date pattern or not, I decide to use a pattern like "yyyyMMdd_HH00" that works fine for everything else than parsing a string.
I create a String date based on the current date on UTC using this pattern and keep it to use it to compose an Url String.
After I need to know how much time I must sleep before the next execution (on each Hour), so I use this date +1 hour to see if the currentDate during this calculation is higher than this date+1... (I'm surely not clear, but it is not the real problem just for curious ^^)
A dirty solution is to avoid this problem is to catch this case and do substitution on a temporary pattern of the 'HH00' with 'HHmm'. It's really dirty because nothing says that later a 'HH00' mean always 'HHmm' but I have nothing better...
          String pattern2 = pattern;
          if (pattern.matches(".*HH00$")) {
               pattern2=pattern.substring(0, (pattern.length()-2))+"mm";
          }Where can I do this bug report ?
Do you see a good solution ?

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);
}

Problem in using String in Implicit Cursor

Hi,
I am facing problem in using String in Implicit Cursor:
I have initialise
DECLARE
v_grant varchar2(4000);
begin
v_grant:='SELECT TABLE_NAME FROM DUMP_USER_TABLES WHERE TABLE_NAME LIKE ';
FOR obj IN (SELECT v_grant||'''BS%''' FROM dual) LOOP

DBMS_OUTPUT.PUT_LINE('THE REVOKE STATEMENT IS'||V_REVOKE);
num := num + 1;
END LOOP;
END;
I am not getting the value from obj.TABLE_NAME its coming as 'obj.TABLE_NAME'
Kindly anyhelp will be needful for me

Besides from what Sybrand already pointed out clearly:
Your example doesn't run at all:
MHO%xe> DECLARE
2 v_grant varchar2(4000);

4 v_grant:='SELECT TABLE_NAME FROM DUMP_USER_TABLES WHERE TABLE_NAME LIKE ';

But:
WHAT are you trying to do anyway?
I cannot parse your code at all...so what is your requirement in human language?

How to parse xml string

Hi! I'm having problems parsing an xml string. I've done DOM and SAX parsing before. But both of them either parse a file or data from an input source. I don't think they handle strings. I also don't want to write the string into a file just so I can use DOM or SAX.
I'm looking for something where I could simply do:
Document doc = documentBuilder.parse( myXMLString );
So the heirarchy is automatically established for me. Then I could just do
Element elem = doc.getElement();
String name = elem.getTagName();
These aren't the only methods I would want to use. Again, my main problem is how to parse xml if it is stored in a string, not a file, nor comming from a stream.
thanks!

But both of them either parse a file or data from an input source. I don't think they handle strings.An InputSource can be constructed with a Reader as input. One useful subclass of Reader is StringReader, so you'd use something likeDocument doc = documentBuilder.parse(new InputSource(new StringReader(myXMLString)));

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

Parsing hexadecimal strings

im an fresher currently in a project on secure hash algorithm
my project is stopped due to certain reasons , further which i cannot proceed.
i woud be grateful to u if some one provides solution to my problem.
int a = (word[i] << 1) or (word[i] >> 32-n)
word is an array that consist of hexadecimal string .
the thing here is for instance , 0x2g46778, 2g46778
when u print(both, individually) using System.out.println yields different results.
the scenario is i have derived word array that consist only number without 0x extension ,
but result yielded is wrong as for the reason mentioned above.
but when i take an array that consist of 0x as string and concat it with every element of word array i get the full number (i.e 0x 2hg4kr7)
again the problem is parsing the hexadecimal string(with ox as extension)
Query:
please tell me whether their is any way for parsing hexadecimal string as ox is not recognized.
or
how to proceed with it such that my string get parsed.
thank u
sincerly
hari hara ganesh dharmarajan

Could you post some sample input and desired output for your project?
What is an array of hex string?
Is it String[] with the contents of each string consisting of the char a-f and 0-9? Eg String[] xx = new String[] {"1234", abcd"};
What does "parsing a hex string" mean? Give an example please.

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.

Parsing xml string does not see the dtd inside jar

Hello,
I have problem parsing an XML string because the DTD file is not found (my DTD file is located inside my application's jar file). I am trying to instruct the parser where the DTD is located. If my DTD would have been on the filesystem directlly things would be working just fine, but i need to keep the DTD inside my JAR.
String dtdLocation = ClassLoader.getSystemResource("mydtd.dtd").toURI().toString();
Document xmlDocument = builder.parse(new ByteArrayInputStream(xmlFile.getBytes()),dtdLocation);The XML string looks something like this:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE Properties SYSTEM "mydtd.dtd">
<Properties>
<Prop>val<Prop>
</Properties>

How can I solve a Parse Error: "There was a problem parsing this package"

Hello;
I developed a really simple app in Flash Pro CC for android. I published it using AIR 13.0 for Android. When I tried to install it I received the Parse Error: "There was a problem parsing this package"
Im not sure if the problem has something to do with my app xml file, but here it is:
<?xml version="1.0" encoding="UTF-8"?>

What do you think is the best to check?

i don't see any problem with your manifest.
try saving your fla and the published files to a new directory and see if the error resolves.

Problem in Converting String to Date

Hi All,
I am having one String
String date = "2006-01-17 15:19:57.0"
I want to parse this String into Date object.
I will really appriciate if somebody helps me out.
Thanks.

You're specifying a 'T' and a timezone in your format, but they're not present in the string you're parsing.
I'm assuming from the way you're printing out the date, that your thinking is along these lines: "sdfInput will parse the input string, no matter what format it's in, and will produce a Date object. That Date object wil have the format specified in sdfInput."
This is wrong on a couple of fronts:
1) DateFormat doesn't magically figure out what format it's supposed to use for the String it's parse()ing. The String has to match the DF's format.
2) Dates don't have formats. Only Strings do. A Date object is just a long. There's no relationship whatsoever between the Date that you get from parse() and the format that was used to produce it. When you print out a Date as you're doing, its toString method is called, which in turn uses a default format for your Locale.
If you want to turn a date string in one format into a date string in another format, use two different DateFormat objects with two different formats. Date date = df1.parse(inputString);
String outputString = df2.format(date);

How to Parse a string into an XML DOM ?

Hi,
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.

public final class DomParser extends Object {
     // Class Variables //
     private static final DocumentBuilder builder;

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.
