I have xml files which are parsed into html with asp&msxml3, texts in XML contain entity &br; where linebreak is wanted.

What kind of line the .dtd must have to make real linebreaks from it. (Is .dtd's rules enough?)

I know this could be done in asp with other processing and even with 'Transform-xsl' but how to do it Easily?

I'm not sure exactly what you mean....could you please explain a bit more?

As far as I understand you want to parse the &br; entity into a real Line break...as far as I know that allready does it...

my .dtd has line
<!ELEMENT TEXT (#PCDATA)>

.xml has lines like:
<TEXT>This is first&br;This is next</TEXT>

.xsl has line:
<p><xsl:value-of select="TEXT"/>

when those are parsed, error about use of unknown entity is displayed.

To pass that error .dtd file has line
<!ENTITY br " " >

which makes &br; -> space.

if i replace previous with anything like
<!ENTITY br "<br>" > or <!ENTITY br "&lt;br&gt;" > or ...

it makes &br; -> "<br>"  (<br> appears as text not real linebreak)

I want it to break.

Hmm...that's weird....

Could you instead try

<!ENTITY br "&#13">
or
<!ENTITY br "&#10">

Not sure which one is line feed and which one is carriage return...

It must have something to do with the ; at the end of the entity....

I'm at the point that I think there has to be a predefined entity for a line break....

Maybe all you need to do is put &#13; wherever you need the line break?

TMan,

As Far as I've checked there is no line feed in XML.

And it is very logically , since XML and presentation are two opposite things , and line-feed is core presenetation , there shouldn't be any line-feed in XML.

In xml you can use <BR/> ( if it's XSL>>HTML)

DreamMaster:
I noticed the missing ";" also, but still. &#13; becomes linebreak in source html, but those, as generally known, are rendered as single space. Must I place the text in <PRE></PRE> to get it right.


avner:
<br/> might be the best choise but, what is wrong:

> my .dtd has line
> <!ELEMENT TEXT (#PCDATA)>

using <BR/> in text like:
<TEXT>This is first<BR/>This is next</TEXT>

Results in Validator error: "Element content is invalid according to the DTD/Schema. Expecting: #PCDATA"


xml-file includes dtd using
<!DOCTYPE MYFILE SYSTEM "myfile.dtd" >

That's because your declaration is wrong , you should be using :

<!ELEMENT BR EMPTY>
