perl question

Ottawa_IWOV

I am curious about how to do something in perl

I have an array

my @values;

(it contains multiple values - see below)

<value>value1</value>
<value>value2</value>
<value>value3</value>

Therefore...

my $x = 0;
for ($x..$#values)
{
my $value = @values[$x];
print $value;
$x++;
}

This code will print all the values in the array.

What I would like to do is add a tag, say <hello> to the front of the array, and add a closing tag </hello> to the end of the array.

The resulting output would look like...

<hello><value>value1</value><value>value2</value><value> value3</value></hello>

I cannot seem to figure out how to achieve this without having the output read...

<hello><value>value1</value></hello><hello><value>value2</value></hello<hello><value>value3</value></hello>

Any help would be well received, thanks!

Did you even pay attention to the last response to a similar question you posted? Here, I'll post it again:


First of all, you are once again using the for loop improperly (I believe someone else corrected you on this in an earlier post). You probably want this construct:

for ($x = 0; $x < $#values; $x++) {
}

That way you can use $x the way you want to in your block of code inside the loop.


Second, you really need to take a perl (or any programming) class. If you are going to continue to develop perl code, you really need to at least try to understand the basics of code development. What you are asking is incredibly basic. How about before your for loop, you print "<hello>" and after your for loop you print "</hello>". Do yourself a favor and take a programming class.
