Re: How do I specify a & character in Grep?

The answer was already presented with the use of the [url] context: embedded ampersands and other special characters in URLs are represented as their HEX-escaped equivalents. In the case of ampersand, the equivalent code is %26. You can automate this by wrapping [url]...[/url] around any text which needs to be passed as a parameter to *any* WebDNA context, not just grep.The general solution to any problem like this is to wrap every parameter inside [url]:[grep search=[url]...some text here which may contain ampersand...[/url]&replace=[url]...[/url]]...[/grep]This ensures that any 'special' characters get passed thru without modification or misinterpretation. Ampersands as delimiters was not our invention: it's how browsers send URLs to servers, and we purposely chose it so as to keep things consistent for web programmers who are already accustomed to URLs.Technical Support ********************************** Smith Micro, Internet Solutions Div | eCommerce (WebCatalog) 16855 West Bernardo Drive, #380 | ------------------------- San Diego, CA 92127 | Software & Site Development WebCatalog Support: (858) 675-0632 | http://www.smithmicro.com Fax: (858) 675-0372 **********************************------------------------------------------------------------- This message is sent to you because you are subscribed to the mailing list
