Hi dev-xml, I have a question about e-mail validation with regular expressions. I've seen a lot of regular expressions out there to validate RFC 2822 e-mail addresses. Seems like there are many variants but few for the XML schema flavor of regex. I've written on such expression and was wondering what people think of it, if is satisfies the standard and whether people know of any better email Regex for XML schema. I'm also not sure if display names are allowed to have quotes around them like: "Ben Azan" <ben.aza@g...>. Gmail does this, but I can't seem to find it in the RFC 2822. My goal was to support display-names as well as quoting and \ for escaping characters in the local-part of the e-mail. ------------------------------------------------------------------------------
Here is the xsd code:
<?xml version="1.0" encoding="UTF-8"?> <xsd:schema xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:e="http://rep.oio.dk/email" targetNamespace="http://rep.oio.dk/email" elementFormDefault="qualified" version="1.0"> <xsd:element name="email" type="e:emailType"/> <xsd:simpleType name="emailType"> <xsd:restriction base="xsd:string"> <xsd:pattern value="((\S*\s*)*<(([a-zA-Z0-9!#$%&'\*\+/=\?\^`\{\}\|~\._-])|(".+")|(\\.))+@([a-zA-Z0-9-])+(([a-zA-Z0-9-])*\.([a-zA-Z0-9-])+)+>)|((([a-zA-Z0-9!#$%&'\*\+/=\?\^`\{\}\|~\._-])|(".+")|(\\.))+@([a-zA-Z0-9-])+(([a-zA-Z0-9-])*\.([a-zA-Z0-9-])+)+)"/> </xsd:restriction> </xsd:simpleType> </xsd:schema> ------------------------------------------------------------------------------ This validates e-mail address like: hello world <Joe.\\Blow@e...> "Test Person" <$A12345@http://example.com/> Abc\@def@http://example.com/ "Fred Bloggs"@http://example.com/ !def!xyz%abc@http://example.com/ Random <customer/department=shipping@e...> ------------------------------------------------------------------------------ Many thanks for any input, Ben Azan [Date Prev] | [Thread Prev] | [Thread Next] | [Date Next] -- [Date Index] | [Thread Index] |
