CDATA Question

[mike]

Hi People,

Wondering whether anyone can help me with a beginner question. I would like
to embed some xml within xml. I've tried wrapping it with CDATA but no
success. What I would like to achieve is something like this:

<xml>
<msg type='methodCall'>
<method name='Stop'>
<params Id='200701081215'
Dest='Some text here'
Source='<xml><Person name='Mike'></Person></xml>'
/>
</method>
</msg>
</xml>

Is such a thing possible?

</msg>
</xml>

You cannot have elements named 'xml'.

Other than that, would something like this work?:

<yml>
<msg type='methodCall'>
<method name='Stop'>
<params Id='200701081215' Dest='Some text here'>
<Source>
<yml><Person name='Mike'></Person></yml>
<Source>
</method>
</msg>
</yml>

Hi Mike,

CDATA sections cannot be placed inside an attribute value. You can have
something like below, escaping < and > with &lt; and &gt;. Note that
the Source attribute contains a string, you need to parse that to get
XML:

<xml>
<msg type="methodCall">
<method name="Stop">
<params Id="200701081215" Dest="Some text here"
Source="&lt;xml&gt;&lt;Person
name=&apos;Mike&apos;&gt;&lt;/Person&gt;&lt;/xml&gt;"
/>
</method>
</msg>
</xml>

Another thing is that the names starting with xml are reserved, you can
use them but it is recommended not to use them.

Best Regards,
George

If you could perhaps explain *why* you want to do this, it would help us
find a solution.

Hi Peter,

Thanks for taking the trouble. I believe I will do as George suggests. My
data was not very illustrative in my sample so I can understand your
question. For the sake of completeness, the "WHY" is as follows:

I'm transmitting a string of XML over a socket to a server. I want the
server to parse the XML and store bits of it in a database. But part of what
I want to transmit and store is another complete piece of XML. So, I want to
transmit an XML string, parse it to extract xml from one of its elements and
store THAT XML in a database.

The simple replacement of the "<" and ">" will do for now.

Thanks for taking the trouble,

MIKE
