Comparing the value of the creationInstant attribute to the value of the validUntil attribute, we see that the metadata is valid for two weeks. The <mdattr:EntityAttributes> extension element [CS 2] includes a single entity attribute. The entity attribute claims that the entity is "self-certified," a presumably desirable quality.
AOL Mail is focused on keeping you safe while you use the best mail product on the web. One way we do this is by protecting against phishing and scam emails though the use of AOL Official Mail.
This article lists the character entity references that are valid in HTML and XML documents. A character entity reference refers to the content of a named entity. An entity declaration is created in XML, SGML and HTML documents (before HTML5) by using the <!ENTITY name "value"> syntax in a Document type definition (DTD).
AOL may send you emails from time to time about products or features we think you'd be interested in. If you're ever concerned about the legitimacy of these emails, just check to see if there's a green "AOL Certified Mail" icon beside the sender name. When you open the email, you'll also see the Certified Mail banner above the message details.
Matches the ending position of the string or the position just before a string-ending newline. In line-based tools, it matches the ending position of any line. ( ) Defines a marked subexpression, also called a capturing group, which is essential for extracting the desired part of the text (See also the next entry, \n). BRE mode requires \( \). \n
A string homomorphism (often referred to simply as a homomorphism in formal language theory) is a string substitution such that each character is replaced by a single string. That is, f ( a ) = s {\displaystyle f(a)=s} , where s {\displaystyle s} is a string, for each character a {\displaystyle a} .
A string literal or anonymous string is a literal for a string value in the source code of a computer program. Modern programming languages commonly use a quoted sequence of characters, formally "bracketed delimiters", as in x = "foo", where , "foo" is a string literal with value foo. Methods such as escape sequences can be used to avoid the ...
In computer science, the Knuth–Morris–Pratt algorithm (or KMP algorithm) is a string-searching algorithm that searches for occurrences of a "word" W within a main "text string" S by employing the observation that when a mismatch occurs, the word itself embodies sufficient information to determine where the next match could begin, thus bypassing re-examination of previously matched characters.
