nesting in XML

[jack]

Hi

I wanna know if nesting of tags inside similar tags is possible in XML.
To be more clear,

is

<person>
<son>
<person>
<son>david</son>
</person>
</son>
</person>

Is this kind of nesting possible in XML?

Please let me know.

Thanks,
Jack

I wanna know

"want to"

<person>
<son>
<person>
<son>david</son>
</person>
</son>
</person>

Sure. Unless you're using someone else's DTD or schema, there aren't
really any restrictions to how your arrange your data. What really
matters is what you do with the XML data afterwards -- that whatever is
parsing the XML knows if and how to differentiate person/son from
person/son/person/son.

Yes. For a real world example, take XHTML:

<object data="foo.png" type="image/png" width="100" height="100">
<object data="foo.gif" type="image/gif" width="100" height="100">
<p>Here would go a detailed description of the image</p>
</object>
</object>

Hi David,

Thanks a lot, so can we nest tags( inside the same tags) as many times
we want or is there any limitation to this nesting? Also, is there a
comprehensive reference for XML Online where I can look up all these
details? I have the Orielly book but it doesnt cover all these details.

Thanks,
Jack

The XML specs at w3c.org are always useful:

(XML) http://www.w3.org/TR/REC-xml/
(XSL) http://www.w3.org/TR/xsl/

(Others) http://www.w3.org/TR/

Google searches will often yield useful results.

Limited only by the ability of your software and hardware to cope with
the depth to which you nest it. XML has no limit of its own.

Also, is there a
comprehensive reference for XML Online where I can look up all these
details? I have the Orielly book but it doesnt cover all these
details.

A good introduction to the principles of XML encoding is the chapter
of the TEI Guidelines "A Gentle Introduction to XML" at
