Matteo TURRA commented on XALANJ-1906:
--------------------------------------
You can do like this:
Suppose the content of your testarea is value
<textarea id="my_id" name="textareaname">
<xsl:choose>
<xsl:when test="not($value/node())"><xsl:value-of
select="''"/></xsl:when>
<xsl:otherwise><xsl:copy-of
select="$value"/></xsl:otherwise>
</xsl:choose>
</textarea>
This way an empty textNode will be output if value have no nodes.
> [xhtml output] Empty element form for non EMPTY declared elements

> - The standards:
> > Empty-element tags MAY be used for any element which has no content,
> > whether or not it is declared using the keyword EMPTY.
> > For interoperability, the empty-element tag SHOULD be used, and
> > SHOULD only be used, for elements which are declared EMPTY.
> (http://www.w3.org/TR/REC-xml/#sec-starttags)
> > C.3. Element Minimization and Empty Element Content
> > Given an empty instance of an element whose content model
> > is not EMPTY (for example, an empty title or paragraph) do
> > not use the minimized form (e.g. use <p> </p> and not <p />).
> (http://www.w3.org/TR/xhtml1/#guidelines)
> - The patch:
> Elements like <p> or <div> aren't declared as EMPTY in the XHTML DTD.
> According to XML and XHTML standards, the <div></div> form should be used
> instead of <div/>. Both are XML (and XHTML) valid, but the second leads to
> strange problems with some browsers (guess who --- IE).
> Hope this helps,
