Yep, but there are a number of ways to go about that. Maybe only the generateFor() method needs to be altered. (other options include: modifying the type of the title member variable from a simple String to a composite object or a collection of Strings, but then the setTitle() method needs to be changed as well...)

I was trying to avoid that. Yes, that was obvious, but: Sorry, no can do :-) The explanation is that if you use the default generateFor() implementation, the title string will be entirely read into a character array --including any markup characters. Then a characters() event is emitted by the ContentHandler, and the parser implementation will gladly take care of generating entity references for any &, <, >, " and '. Short of rewriting the parser to emit element events whenever it receives markup characters through a characters() event, your only option is indeed to parse the string yourself. If it's any consolation: rewriting the parser would definitely be more complicated than this. :-) Greetz, AD -BEGIN PGP SIGNATURE- Version: GnuPG v1.4.1 (Darwin) iD8DBQFC6XzMyHTbFO9b8aARAv7oAKCtT59yYXpudwuAyBOIRYb2qFb1hwCg22va Mm5ioWcnboCiHB7q/jIsq/w= =zqTB -END PGP SIGNATURE- - To unsubscribe, e-mail: [EMAIL PROTECTED] For additional commands, e-mail: [EMAIL PROTECTED]
Re: embedding output escaping
Ok. I see where you're coming from.
But in my case I have hrefs mixed with plain text.
So my setTitle might look something like this.
setTitle(String_From_Properties);
I don't know exactly what that string is, but I know it might have hrefs.
So my XML, if I was creating one, would look like this:
some text http://sample.com";>click more text
And the XSLT would be:
Since I'm matching I would like it to be in the XML.
Now making it appear in the XML is solved.
When I create the FO from that XML it also works.
But when I skip the XML/FO and go straight from Obj to PDF, it gets written
as text.
But I see your point.
In that case I would have to parse the string I'm getting from a properties
file.
I was trying to avoid that.

Well, I still think you don't need to do any escaping (or disable escaping
for that matter).
If you need to have:

There are two things to take into account:
- - our example embedding.tools.AbstractObjectReader doesn't activate
namespace support
- - and it does not offer any support for attributes
You basically have two options:
1) modify the code for AbstractObjectReader to allow namespaces and
attributes (or override the relevant methods in a subclass)
2) generate semantic XML from your object, then transform it via XSLT to FO
For 2), the scenario would look something like:
* use a method similar to setTitle() to set/store the strings for the
destination URL and "Click here". For example store it in member variables
named linkContent and linkDest (and provide getXXX() methods to retrieve
them)
* then, in your XMLReader in the generateFor() method that will process
your object, you create the result element roughly as follows:
...
handler.startElement("link");
handler.element("destination",obj.getLinkDest());
handler.element("content",obj.getLinkContent());
handler.endElement("link");
...
You will then get XML output like this:

Not exactly, nor do I believe you really need to. I think your problem is
caused by the internals of the methods ObjXml.setTitle() and
app.convertObj2XML().
Presumably, the first stores the text as a java.lang.String member variable
of the object in question, while the second writes that String to the
output XML file --as text, so escaping the usual markup characters and/or
quotes.
(Analogous to our own embedding example: in ProjectTeam.java, the
setProjectName() method is only used to store the name as a String. If you
look at ProjectTeamXMLReader.java, you will see that ultimately a new
projectname-element is created and the name is only used as its content.)
I have a feeling the setTitle() method is incorrectly being used. You
expect it to magically transform character data containing markup - --HTML
markup no less-- to a FO element in the output file.
If you just take a closer look at that embedding example, I think you'll be
able to figure it out. If not, just yell.

embedding output escaping
Hello everyone,
This question has probably come up before, but couldn't find it in the
archives
I want to disable output escaping.
Here's an example:

obj.setTitle("http://www.sample.com\";>Sample Title");
}
public static void main(String[] args) {
app.convertObj2XML(obj, "C:\\xmlfile.xml");
app.convertObj2PDF(obj, "C:\\pdffile.pdf");
}
The xml output is '<';a href="http://www.sample.com";'>';Sample
Title'<';/a>';
And on the PDF its just text not a link.
Does anyone know how to escape this?
Fabrizio.
