Bart,
if
you wan't your XML processor to treat the HTML as markup, not as text, you'll
have to *tell* it that it's markup. So,
a)
wrap the text into a container tag like <p>
b)
parse the string into a JDOM
c)
move all child nodes to your BODYTEXT element.
Forgot to tell that i was using xmlOutputter from
org.jdom
and that in our dtd, these <a> elements are
declared, so no validation faults are given...
we
just add all elements to the document structure, except this one
(included in the text) but is a valid xml tag...
thanks, bart
hey,
on one of my projects, i'm working with Jdom
(old version jan. 2000) to parse xml (when validating)
If i want to use html tags between xml tags, the tags
are replaced by "<" or ">"...
example:
<BODYTEXT>this is just text with a
link<a href="link.html">text for link</a>text goes
on</BODYTEXT>
the text between the bodytext is just text,
coming right out of the database. When getting the text from the database,
everything is just fine but when adding this text to the document (while
constructing the doc) and parsing it we get the "<" signs replaced by
"<" etc.
How do i avoid the replacing of these tags
without having to extract the link data of the text and putting it between
xml tags?
regards,bart
