Creating solo tags (i.e. <tag .../>) with WST XML api [message #231843]

Hello,

I have an XML file that I process using the WST API (StructuredDocument,
etc). I use XPath for various parsing jobs and I insert nodes via the
standard DOM API (i.e. node.append(document.createElement(...));).

Is there a way to create an Element that will be saved in the xml file
using it's "short" form (i.e. <a_tag attr1=".."/> instead of <a_tag
attr1=".."></a_tag>.

Thanks in advance,
Cristi.

Only by using IDOMElement.setEmptyTag(true) before inserting it into
the Document. I don't know of a DOM API way of controlling it
before you transform it into a stream, and even then it's a
transformer-specific parameter.

This isn't a DOM issue, it's a serialization issue. So this is
something as Nintin says has to be handled by the IDOMElement extension
to the w3c.org.Element interface.

In general, if you don't have a Text node or another Child Node, then
most serializers will serialize it out as <tag/>, otherwise they may
serialize it as <tag></tag>, depending on the serializer.

It worked. Thanks a lot!

This is not the case of the WST serializer.

Best regards and thanks again for your answers.
