php-iban is a PHP library for parsing and validating IBAN bank account information. All parts of an IBAN can be retrieved, including country code, checksum, BBAN, financial institution or bank code, and where a fixed-length national system is in use, also branch/sort code and account number. The parser was built using regular expressions to adapt the contents of the official IBAN registry available from SWIFT then only manually modified for a few special cases. Various deficiencies in the initial adaptation have since been rectified, and the current version should be a fairly correct and reliable implementation.
EMF Validation Builder is an Eclipse plugin that automates the validation process at the time of saving. This means that resource problem markers are up to date as soon as you save your model. A dependency table is maintained, which allows the validation process to be re-run when necessary. In particular, the tool can be directly used with ECore model files.
Serene is a validation engine that implements the JAXP 1.3 Validation Framework API for RELAX NG based on an algorithm centered on providing good messages and having a clear handling of ambiguity and conflicts. It has an implementation of the JAXP Validation Framework API for ISO Schematron and support for Schematron markup embedded in RELAX NG schemas.
Email Address Validator is a PHP class that allows the developer to validate email addresses according to the RFC 5321 or RFC 5322 standards. It can also check to see if the domain can be resolved to MX RRs. Acceptable local-parts include dot-atom, quoted string, and obsolete. Acceptable domains include domain name, IPv4 address, IPv6 address, and IPv4-mapped IPv6 address. Folding white spaces and nested comments are also supported.
HTML::FormFu is a framework for HTML forms. It aims to be as easy as possible to use for basic Web forms, but with the power and flexibility to do anything else you might want to do (as long as it involves forms). You can configure almost any part of formfu's behavior and output. By default, formfu renders "XHTML 1.0 Strict" compliant markup, with as little extra markup as possible, but with sufficient CSS class names to allow for a wide range of output styles to be generated by changing only the CSS.
