This is not how web developers process the DOM in HTML, especially on the client side.
Should I assume you are processing the value on the server side?
Either way, your post confused me. On the client side , we easily get the value attribute of the input DOM element with Javacript:
If on the server side, normally you use PHP or PERL and you get the attribute value when you submit on the browser to the server.
PHP Example:
or
We web developers do not process HTML files as big strings and use PERL or PHP or any language to extract a value; because this is easily done on both the client or server side with existing built-in methods.
Getting the value of an HTML DOM attribute does not require a script like you have written. Hidden values are normally submitted with HTML forms via the $_POST method.
This means on the server side, you would simple read the value of $_POST['value'] when the DOM element is submitted.
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.

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:

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"}'

iconv_substr
ICONV_SUBSTR(3) 1 ICONV_SUBSTR(3)iconv_substr - Cut out part of a stringSYNOPSIS
string iconv_substr (string $str, int $offset, [int $length = iconv_strlen($str, $charset)], [string $charset = ini_get("iconv.inter-
nal_encoding")])
DESCRIPTION
Cuts a portion of $str specified by the $offset and $length parameters.
PARAMETERS
o $str
- The original string.
o $offset
- If $offset is non-negative, iconv_substr(3) cuts the portion out of $str beginning at $offset'th character, counting from zero.
If $offset is negative, iconv_substr(3) cuts out the portion beginning at the position, $offset characters away from the end of
$str.
o $length
- If $length is given and is positive, the return value will contain at most $length characters of the portion that begins at
$offset (depending on the length of $string). If negative $length is passed, iconv_substr(3) cuts the portion out of $str from
the $offset'th character up to the character that is $length characters away from the end of the string. In case $offset is also
negative, the start position is calculated beforehand according to the rule explained above.
o $charset
- If $charset parameter is omitted, $string are assumed to be encoded in iconv.internal_encoding. Note that $offset and $length
parameters are always deemed to represent offsets that are calculated on the basis of the character set determined by $charset,
whilst the counterpart substr(3) always takes these for byte offsets.
RETURN VALUES
Returns the portion of $str specified by the $offset and $length parameters.
If $str is shorter than $offset characters long, FALSE will be returned.
