[digester] reading embedded HTML (or other mixed text)

[Bill Keese <bi...@tech.beacon-it.co.jp>]

Is there any way to tell digester to read in the entire content of an
element (including text and sub-elements) as a single String? For
example, if I persist e-mail to XML, I'd like to use digester to read
the e-mail address list, etc., but the HTML content of the mail should
be read verbatim.

<email>
<to>bill</to>
<subject>test</subject>
<content> Hello world! <i>This text is italic</i> and <b>this text is
bold</b> This is plain text.</content>
</email>

====>

Class email {
List to, cc, bcc;
String subject;
String content; // HTML content
};

Yup, I should have said "XHTML". The point was that the content is
free-form (arbitrary levels of nesting of tags, mixed content, etc.), so
it isn't suitable for parsing by normal pattern-matching Digester rules.
But CDATA or NodeCreateRule seem to do the trick.

Thanks!

Hi Bill,

HTML is not valid XML. Digester uses a standard XML parser to parse the
input, so it is not possible to process an input document which is not
valid XML.

As Jose has said in a separate reply, you could wrap your HTML in CDATA
tags in the input document. The xml parser will then see the contents of
that cdata section as just a text string - and so will Digester.

Alternatively, you could use XHTML, which most browsers support. In this
case, you could then use NodeCreateRule.

Regards,

Simon

Try surrounding the content with <![CDATA[ ... ]]>

<email>
<to>bill</to>
<subject>test</subject>
<content><![CDATA[ Hello world! <i>This text is italic</i> and <b>this 
text is
bold</b> This is plain text.]]></content>
</email>
