In the case of a web application, the programmer may use the same regular expression to validate input on both the client and the server side of the system. An attacker could inspect the client code, looking for evil regular expressions, and send crafted input directly to the web server in order to hang it. [9]
A regular expression (shortened as regex or regexp), [1] sometimes referred to as rational expression, [2] [3] is a sequence of characters that specifies a match pattern in text. ...
RE2 is a software library which implements a regular expression engine. It uses finite-state machines, in contrast to most other regular expression libraries. RE2 supports a C++ interface. RE2 was implemented by Google and Google uses RE2 for Google products. [3]
The above graph represents a state-machine that takes user input as a series of bytes representing ASCII characters and control codes. 48..57 is equivalent to the regular expression [0-9] (i.e. any digit), so only sequences beginning with a digit can be recognised. If 10 (line feed) is encountered, the program is done. 46 is the decimal point ...
Java Bean Validation originated as a framework that was approved by the JCP as of 16 November 2009 and accepted as part of the Java EE 6 specification. The Hibernate team provides with Hibernate Validator the reference implementation of Bean Validation and also created the Bean Validation TCK any implementation of JSR 303 needs to pass.
The system can be monitored during the execution itself (online) or after the execution e.g. in form of log analysis (offline). The verifying code is integrated into the system (as done in Aspect-oriented Programming) or is provided as an external entity. The monitor can report violation or validation of the desired specification.
It was proposed at the 2012 RDF Validation Workshop [3] as a high-level, concise language for RDF validation. The shapes can be defined in a human-friendly compact syntax called ShExC or using any RDF serialization formats like JSON-LD or Turtle. ShEx expressions can be used both to describe RDF and to automatically check the conformance of RDF ...
