Hi,
I made a test program which outputs a < , a \n and a
System.getProperty("line.separator").
The simple \n comes out fine, the only problem I have is with the
System.getProperty("line.separator").
Thank you

HI Jean-Francois,
please post a small Java program that creates a small DOM, for example a
document with only a root element, that has a text node child with say
a '>' and a '\n' in it. Also your code to serializer the DOM so I can see
how the comes about.
I'm willing to investigate, but I'm not willing to spend time trying to
create the testcase.
Thanks,
- Brian

PM RE: Serializing a DOM tree to XML
file, customize entities
replacement
Hi,
Is that option supposed to change the String the transformer will use to
replace line separators? I just tried it and it changes nothing at all, my
XML output is still filled with strings.
What I am looking for would be a way to disable output escaping for
everything, except the characters I listed in my first post.
If I add the processing instruction in my DOM using:
ProcessingInstruction pi =
doc.createProcessingInstruction(Result.PI_DISABLE_OUTPUT_ESCAPING, "");
root.getParentNode().insertBefore(pi, root);
I get the desired result, but then I would need to manually escape all the
<
> & ' " characters.
Thank you

Hi Jean-Francois,
I think there are solutions to this, but all of them are Xalan specific.
I assume that you are running your DOM through the identity transformation
in order to serialize it. This is the most portable way to do it.
Once you get your Transformer object, even though it is the identity
transform, you can set some properties via JAXP. I suggest you try this:
javax.xml.transform.Transformer t = ...
t.setOutputProperty("{http://xml.apache.org/xalan}line-separator","; ");
If you had a stylesheet this could be done like this:
<xsl:out xalanPrfx:line-separator=" "
xmlns:xalanPrfx="http://xml.apache.org/xalan"; />
but you don't have a stylesheet.
Still JAXP lets you over-ride xsl:output attribute values, and I think this
should work even when there is no stylesheet.
So my suggestion is to not output the '\n' but to output a space. Of
course if you want something else like "-EndOfLine-" then do this:
t.setOutputProperty("{http://xml.apache.org/xalan}line-separator","-EndOfLin
e-");
Hope this does the job for you.

PM Serializing a DOM tree to XML file,
customize entities replacement
Hi,
I am currently building a DOM tree using the Xerces implementation and then
write it to a String using the Xalan transformer. I currently have a
problem with line breaks (I use System.getProperty("line.separator")) in
the
text nodes being replaced by the entity . The application I am trying
to then send the XML message to does not transform that entity back into a
line break.
Is there a way to tell Xalan to use either a custom set of entities, or to
remove specific entities from this automatic treatment or am I force the
reparse manually the result to replace the back to a normal line
separator. Having a way to tell the transformer to use a custom set of
entities would be my best option since the application I communicate with
only threats:
- <
- >
- &
- '
- "
Thank you
