Re: What is the use of non-leafElement' VALUE ?
Easy: Consider the following markup:
<book>
<title>Some Useful Stuff</title>
<chapter>
<para>This demonstrates the value of
<emph>mixed</emph> content.</para>
</chapter>
</book>
There is real meaning associated with having "value" in the
<para> element other than the "value" contains in the
sub-element <emph>.
'Nuff said,

Hi,
I have one generic question
on XML structure [XML element].
If an XML element represents an
object then element's attributes would be properties of that
object.
Then any subelement [be it leaf or
non-leaf] would represent the hierarchy of the objects
[containment].
If the element is a leaf node then
that element's value will be meaning full.
BUT if the element is not a leaf
node then what is the BUSINESS/Real-life meaning of having value in that
element ?
My understanding is that an
element's attributes and its sub-elements are enough to represent an
object.
Example :
<?xml version="1.0"
encoding="ISO-8859-1"?>
<employmentDetails>
Some
value
<EmployerID>097</EmployerID>
<EmploymentStatus>Active</EmploymentStatus>
<AnnualCompensation>$100000</AnnualCompensation>
</employmentDetails>
What is the business meaning of
allowing element value for non-leaf element in XML W3C standards.
Thanks in advance for sharing your
thoughts/inputs/ideas.
Regards,
RNS
