${parameter:offset}
${parameter:offset:length}
Substring Expansion. Expands to up to length characters of
parameter starting at the character specified by offset. If
length is omitted, expands to the substring of parameter start-
ing at the character specified by offset. length and offset are
arithmetic expressions (see ARITHMETIC EVALUATION below). If
offset evaluates to a number less than zero, the value is used
as an offset from the end of the value of parameter. Arithmetic
expressions starting with a - must be separated by whitespace
from the preceding : to be distinguished from the Use Default
Values expansion. If length evaluates to a number less than
zero, and parameter is not @ and not an indexed or associative
array, it is interpreted as an offset from the end of the value
of parameter rather than a number of characters, and the expan-
sion is the characters between the two offsets. If parameter is
@, the result is length positional parameters beginning at off-
set. If parameter is an indexed array name subscripted by @ or
*, the result is the length members of the array beginning with
${parameter[offset]}. A negative offset is taken relative to
one greater than the maximum index of the specified array. Sub-
string expansion applied to an associative array produces unde-
fined results. Note that a negative offset must be separated
from the colon by at least one space to avoid being confused
with the :- expansion. Substring indexing is zero-based unless
the positional parameters are used, in which case the indexing
starts at 1 by default. If offset is 0, and the positional
parameters are used, $0 is prefixed to the list.
Hi,
I have a file with 6 columns. First 3 columns together make unique record. I have a variable ($v) which hold a value that is obtained by a caliculaion. I have to replace value in 5th columnn with the value of the variable ($v). The value $v is caliculated from col4 and col6 values.

xml::dom::characterdata
XML::DOM::CharacterData(3pm) User Contributed Perl Documentation XML::DOM::CharacterData(3pm)NAME
XML::DOM::CharacterData - Common interface for Text, CDATASections and Comments
DESCRIPTION
XML::DOM::CharacterData extends XML::DOM::Node
The CharacterData interface extends Node with a set of attributes and methods for accessing character data in the DOM. For clarity this set
is defined here rather than on each object that uses these attributes and methods. No DOM objects correspond directly to CharacterData,
though Text, Comment and CDATASection do inherit the interface from it. All offsets in this interface start from 0.
METHODS
getData and setData (data)
The character data of the node that implements this interface. The DOM implementation may not put arbitrary limits on the amount of
data that may be stored in a CharacterData node. However, implementation limits may mean that the entirety of a node's data may not fit
into a single DOMString. In such cases, the user may call substringData to retrieve the data in appropriately sized pieces.
getLength
The number of characters that are available through data and the substringData method below. This may have the value zero, i.e., Char-
acterData nodes may be empty.
substringData (offset, count)
Extracts a range of data from the node.
Parameters:
offset Start offset of substring to extract.
count The number of characters to extract.
Return Value: The specified substring. If the sum of offset and count exceeds the length, then all characters to the end of the data
are returned.
appendData (str)
Appends the string to the end of the character data of the node. Upon success, data provides access to the concatenation of data and
the DOMString specified.
insertData (offset, arg)
Inserts a string at the specified character offset.
Parameters:
offset The character offset at which to insert.
arg The DOMString to insert.
deleteData (offset, count)
Removes a range of characters from the node. Upon success, data and length reflect the change. If the sum of offset and count exceeds
length then all characters from offset to the end of the data are deleted.
Parameters:
offset The offset from which to remove characters.
count The number of characters to delete.
replaceData (offset, count, arg)
Replaces the characters starting at the specified character offset with the specified string.
Parameters:
offset The offset from which to start replacing.
count The number of characters to replace.
arg The DOMString with which the range must be replaced.
If the sum of offset and count exceeds length, then all characters to the end of the data are replaced (i.e., the effect is the same as
a remove method call with the same range, followed by an append method invocation).
