Hi there,
Could someone please suggest an open source implementation of a
validating XML parser ? I am interested in how this thing can
(should?) be designed. In particular how the errors should be handle:
1. If one at a time, it make is difficult to handle from a GUI, since
only one error can be corrected at a time
2. All errors are reported, which means that false positive may be
reported
Also how does the implementation report which elements contains
errors (using name, file position...).
Thanks

I am interested in how this thing can
(should?) be designed. In particular how the errors should be handle:
This is always a problem, since the author cannot know what the user
wants to do on a given occasion: stop or continue.
1. If one at a time, it make is difficult to handle from a GUI, since
only one error can be corrected at a time
And when the first error is corrected, the validation must start again
from the beginning.
2. All errors are reported, which means that false positive may be
reported
This is very common because an error may not be recognisable as such
until some later condition makes it impossible to continue.
Also how does the implementation report which elements contains
errors (using name, file position...).
onsgmls reports line number and character position, and optionally the
names of open entities. In a synchronous typographical interface, an
error can be indicated by many means (highlighting, change of focus,
error log, ...)

I honestly believe XPath to the offending point is a more meaningful way
to report this, but whether it's more useful depends in part on the
quality of the tooling available to the user (and/or the user's skill
level). This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics |

I've been persuaded here in the past that serving xhtml is a bad thing (tm).
I want the extra constraints xhtml imposes.
It has been suggested before to create a DTD which requires these &
includes all the requirements of HTML 4.01 & validate against that.

Hi all,
I have a very simple page that Firefox has problems with:
www.absolutejava.com/testing.htm
First of all, this page seems to be perfectly valid XHTML Strict. Both
the W3C validator as well as Page Valet indicate it is valid. The page
is being served with the proper MIME type of "application/xhtml+xml".
Unfortunately, Firefox will not display the page due to a non-breaking

We have developed about 80 XML documents, each probably 150 lines long, that
are all supposed to conform to a schema. My understanding is the way to
show that an XML document conforms to a schema is to include a reference to
the XSD in the XML document, and check that it is valid.
Some other members of the project team don't want to include a reference to
the XSD in the XML documents, citing possible differences in parsers.

Is there a way to prevent the user from leaving a tab on a TabControl until
all the controls on that tab have finished validating?
The problem I am experiencing is when a control fails its validating event
and the user clicks another tab things get messy. Ideally, I think the best
solution is not to leave a tab until the validating event has completed
successfully.
Thanks,

Hello there,
I am looking for suggestions for designing a simple file format
based on XML. It will only contain text information (no binary data).
1. If I have a choice: Element or Attribute ?
2. Do I need to define my own file version (maybe as the first XML
element) ?
3. Do I need to provide a DTD or XML schema ?
Thanks for inputs,

Hello folks,
I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
The problem is that using the GNU compilers, it seems that the internal comparison operator "<=>" tries to promote arguments from unsigned to signed.
This is as boiled down as I can make it.
