Converting HTML to Plain Text in Inbound Email

Hi folks,

 

Is there any way I can convert the body of an inbound email from html to Plain Text? I've set up a service to email directly into chatter, but html emails sent from my organisation into Chatter are all of over 1,000 characters in length (even if I send a blank email). So, I'm looking for a way to strip the body text from the emails and discard all the html "nonsense", rather than force users to send emails in Plain Text format, which they'll be disinclined to do.

 

Any help anyone can give would be massively appreciated.

 

Thanks,

Lee

Where is the parsing method you found?

Use .stripHtmlTags(htmlInput) String method:

But be aware:

The stripHtmlTags function does not recursively strip tags; therefore, tags may still exist in the returned string. Do not use the stripHtmlTags function to sanitize input for inclusion as a raw HTML page. The unescaped output is not considered safe to include in an HTML document. The function will be deprecated in a future release.

Adrian Larson suggests:

Pattern tagPattern = Pattern.compile('<\/?\w*\b[^>]*>');
String plainTextBody = tagPattern.matcher(htmlBody).replaceAll('');

You'll also need to escape the backslash with double backslashes:

Pattern tagPattern = Pattern.compile('<\/?\\w*\\b[^>]*>');
  
String regExp = '<style>[^<]*<\\/style>|<\\/?\\w*\\b[^>]*>';
Pattern tagPattern = Pattern.compile(regExp);
String plainTextBody = tagPattern.matcher(emailContent).replaceAll('');
