How about the "Substring Parameter Expansion" (possibly not available in all POSIX compliant shells):
man bash:
Quote:
${parameterffset}...
If offset evaluates to a number less than zero, the value is used as an offset in characters from the end of the value of parameter.

xml::dom::characterdata
CHARACTERDATA(1) User Contributed Perl Documentation CHARACTERDATA(1)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).
