Hi,
Is it possible to delcare hashes in KSH the way we do it in Perl.
Like I want to declare something like:
fruits="Juicy"
fruits="healthy"
fruits="sour"
echo fruits
Ofcourse this piece of code does not work in KSH. Please let me know if there is a way of doing it in KSH.

Any clue to write something to a particular location in Perl?
Suppose
$line = ‘abc cde 1234”
How to write ( example string "test") on location 4 without parsing the whole line.
Output should be $line = ‘abctest 1234”
this is not search and replace. just to add substring into... (3 Replies)
Let's assume that I have a file with contents delimited by pipe:
"The mouse|ran up|the|clock"
"May|had a|little|lamb"
How would I use 'substr' to get the 3rd field. For example, "the" from the first line, and "little" from the second line?

Hi Everyone,
$tmp="20090620231013";
$tmp = substr($tmp,0,8)." ".substr($tmp,8,2).":".substr($tmp,10,2).":".substr($tmp,12,2);
So my output is:
20090620 23:10:13.
I only can think substr is easy, any perl can do this just one line very simple efficient one? :eek:
Thanks (3 Replies)

I want to match the number exactly from the variable which has multiple numbers seperated by pipe symbol similar to search in egrep.below is the code which i tried

I have a command like this:
listdb ID923 -l |gawk '{if (substr($0,37,1)==1 && NR == 3)print "YES" else if (substr ($0,37,1)==0 && NR == 3) print "NO"}'
This syntax doesn't work. But I was able to get this to work:
listdb ID923 -l |gawk '{if (substr($0,37,1)==1 && NR == 3)print "YES"}'

Can I use substr to achieve the same task?
Thanks! (8 Replies)

html::pullparser
HTML::PullParser(3) User Contributed Perl Documentation HTML::PullParser(3)NAME
HTML::PullParser - Alternative HTML::Parser interface
SYNOPSIS
use HTML::PullParser;
$p = HTML::PullParser->new(file => "index.html",
start => 'event, tagname, @attr',
end => 'event, tagname',
ignore_elements => [qw(script style)],
) || die "Can't open: $!";
while (my $token = $p->get_token) {
#...do something with $token
}
DESCRIPTION
The HTML::PullParser is an alternative interface to the HTML::Parser class. It basically turns the HTML::Parser inside out. You associate
a file (or any IO::Handle object or string) with the parser at construction time and then repeatedly call $parser->get_token to obtain the
tags and text found in the parsed document.
The following methods are provided:
$p = HTML::PullParser->new( file => $file, %options )
$p = HTML::PullParser->new( doc => $doc, %options )
A "HTML::PullParser" can be made to parse from either a file or a literal document based on whether the "file" or "doc" option is
passed to the parser's constructor.
The "file" passed in can either be a file name or a file handle object. If a file name is passed, and it can't be opened for reading,
then the constructor will return an undefined value and $! will tell you why it failed. Otherwise the argument is taken to be some
object that the "HTML::PullParser" can read() from when it needs more data. The stream will be read() until EOF, but not closed.
A "doc" can be passed plain or as a reference to a scalar. If a reference is passed then the value of this scalar should not be
changed before all tokens have been extracted.
Next the information to be returned for the different token types must be set up. This is done by simply associating an argspec (as
defined in HTML::Parser) with the events you have an interest in. For instance, if you want "start" tokens to be reported as the
string 'S' followed by the tagname and the attributes you might pass an "start"-option like this:
$p = HTML::PullParser->new(
doc => $document_to_parse,
start => '"S", tagname, @attr',
end => '"E", tagname',
);
At last other "HTML::Parser" options, like "ignore_tags", and "unbroken_text", can be passed in. Note that you should not use the
event_h options to set up parser handlers. That would confuse the inner logic of "HTML::PullParser".
$token = $p->get_token
This method will return the next token found in the HTML document, or "undef" at the end of the document. The token is returned as an
array reference. The content of this array match the argspec set up during "HTML::PullParser" construction.
$p->unget_token( @tokens )
If you find out you have read too many tokens you can push them back, so that they are returned again the next time $p->get_token is
called.
EXAMPLES
The 'eg/hform' script shows how we might parse the form section of HTML::Documents using HTML::PullParser.
