I am using JDK 1.5. I tried to use substring() to extract lastname,
firstname, fullname, etc. from the following 'sample' string. For some
reason, the substring() is NOT working right. Please help. Also, what's the
best way to extract fields from a string (or from a file) like this? java/VB
Script? PERL? Thanks.String sample = "<a
href="http://email.people.yahoo.com/py/psEmailVcard.vcf?Pyt=Tps&amp;srch=email&amp;ext=vc ard.vcf&amp;FirstName=Bush&amp;LastName=George&amp ;FullName=George+Bush&amp;City=Washington&amp;Stat e=DC&amp;Country=US&amp;CountryCode=US&amp;Email=g &amp;URL=">vCard</a>";String
firstName = sample.substring(sample.indexOf("FirstName=") +10,
sample.indexOf("&amp;LastName"));String lastName =
sample.substring(sample.indexOf("LastName=") +09,
sample.indexOf("&amp;FullName"));String fullName =
sample.substring(sample.indexOf("FullName=") +10,
sample.indexOf("&amp;City"));.....

So..
a) What's it doing?
b) What do you expect it to do?
c) Can you provide a *compilable* code example that demonstrates?

> firstName = sample.substring(sample.indexOf("FirstName=") +10,
> sample.indexOf("&amp;LastName"));String lastName =
> sample.substring(sample.indexOf("LastName=") +09,
> sample.indexOf("&amp;FullName"));String fullName =
> sample.substring(sample.indexOf("FullName=") +10,
> sample.indexOf("&amp;City"));.....

And as an aside.. Please refrain from compacting code like this,
it makes it very hard to read (and does not make it 'short')..

It gives "String index out of range" error. It seems as if '&amp;' is not
recognized by String.indexOf(), or anything with ';' in front, for that
matter. If I use '&amp' (without ';'), as in

firstName = sample.substring(sample.indexOf("FirstName=") +10,
sample.indexOf("&amp"));

it only worked with the firstName

if I use

String lastName = sample.substring(sample.indexOf("LastnameName=") +10,
sample.indexOf("FullName="));

it gives "String index out of range" error.

Thanks.

Hi!
Have a look at the Java API.
The method throws an IndexOutOfBoundsException, if either
endIndex<beginIndex, beginIndex is negative or if endIndex >
sample.length().

So probably your beginIndex is too high (you add +10...)
Probably one String is not found, then indexOf returns -1, if I remember
correct and this would cause an IndexOutOfBoundsException in substring.

bye, Ralf

Perhaps "LastnameName=" is not found... isnt it "Lastname=" ?

Hello. Can you explain to me why I also got this
message in my email, from a person who calls
themselves 'Thomas'? Is that you?

If yes, I need to make something clear. Do not send me
email. Posting messages to Usenet newsgroups should
not be seen as an invitation to strike up a private
conversation.

And while I'm on the subject..
People will generally have more respect and time for
somebody who calls themselves by their *own* name.

If my guess is correct, Peter/Thomas are the same
person, so one name has to be ..wrong.

People might have any number of reasons not to
use their own name, when posting to a public
forum (for fear of racism or sexism, for example),
but please choose *one* name and stick to it.

Even more importantly, please do not use a name
that implies you are from a *different* culture/race/sex
than what you actually are.

If you wish to use a false name, please make it an
*obviously* false name - so that people do not jump
to the wrong conclusions about the words and
concepts that you will understand.

Hmm, that's a good question. I assumed the answer would be "use
java.net.URL" but there's no way to parse the query string. You can use
getQuery() to get the whole thing, which seems a bit safer than your method.

You can look at this code. It has a trace option at the top. I set it to
true. It will do what you want but I am not happy with it. I think I can
clean it up and make it tighter. Anyway, here ya go:

public class Parsetest
{
static boolean trace = true;
public static void main(String[] args)
{
String sample = "<a href="
+
"http://email.people.yahoo.com/py/psEmailVcard.vcf?Pyt=Tps&amp;srch=email&amp;ext=vc ard.vcf&amp;FirstName=George&amp;LastName=Bush&amp ;FullName=George+Bush&amp;City=Washington&amp;Stat e=DC&amp;Country=US&amp;CountryCode=US&amp;Email=g &amp;URL="
+ ">vCard</a>";
String firstName = "", lastName = "", fullName = "";
String city = "", state = "", country = "", countryCode = "",
email = "";

sample = sample.replace("&amp", "");
sample = sample.replace("=", " ");
String[] token = sample.split(";");
int i = 0;

for (i = 0; i < token.length; i++){
if (trace)
System.out.println("Queued (length, value) " +
token[i].length() + " "+ token[i]);

if (token[i].length()> 3 &
token[i].substring(0, 4).equals("City")){
city = token[i].substring(4).trim();
} else if (token[i].length()> 4 &
token[i].substring(0, 5).equals("Email")){
email = token[i].substring(5).trim();
} else if (token[i].length()> 4 &
token[i].substring(0, 5).equals("State")){
state = token[i].substring(5).trim();
} else if (token[i].length()> 6 &
token[i].substring(0, 7).equals("Country")){
country = token[i].substring(7).trim();
} else if (token[i].length()> 7 &
token[i].substring(0, .equals("LastName")){
lastName = token[i].substring(.trim();
} else if (token[i].length()>7 &
token[i].substring(0, .equals("FullName")){
fullName = token[i].substring(.trim();
fullName = fullName.replace("+", " ");
} else if (token[i].length()> 8 &
token[i].substring(0, 9).equals("FirstName")){
firstName = token[i].substring(9).trim();
} else if (token[i].length() > 9 &
(token[i].substring(0, 10).equals("CountryCode"))) {
countryCode = token[i].substring(11).trim();
} else
if (trace)
System.out.println("Not Used: " + token[i]);
}
// test
System.out.println("firstName: " + firstName);
System.out.println("lastName: " + lastName);
System.out.println("fullName: " + fullName);
System.out.println("city: " + city);
System.out.println("state: " + state);
System.out.println("country: " + country);
System.out.println("Country Code: " + state);
System.out.println("Email: " + email);

}
