Re: Basic question on XML structure

I'm no expert in XML, but here are my 2 cents...

Whenever you nest a set of repeated elements inside a parent element, the parent element can be considered an array. Each repeated element is an item within the array.

So, for:

<children>
<child>
<name>Peter</name>
</child>
<child>
</name>Jill</name>
</child>
</children>

You can have an array called "children" that would contain two items: "Peter", "Jill".

Depending on the XML technology you are using, the <children> tag can be very helpful because it allows the technology to create the array for you. Some XML technologies may require you use the <children> tag because of the way those technologies work beneath the covers.

You can create an array without the <children> tag, but you may have to code and create it yourself instead of letting an XML parser or tool do it for you.

Can't you see where the array is and isn't in this structure:

Lets make is visiual:

<client>
<name>bill</name>
<children>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
<child>
<name>alex</name>
</child>
<child>
<name>peter</name>
</child>
</children>
<address>My home street</address>
</client>

<client>
<name>bill</name>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
<address>My home street</address>

I don't see it. I need another clue.

Or else save us all time and just tell us.

I can't spot the difference between your snippet and the OP's apart from
the
whitespace, which will of course be ignored by a standards compliant
parser
anyway.

Did I miss something else?

You express the XML snippits wrong, it should be

<client>
<name>bill</name>
<children>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
</children>
</client>

<client>
<name>bill</name>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
</client>

The first structure is weel structured, the second isn't.

[WEB400] Basic question on XML structure






Hi all,

A little inexperienced in xml here.

Compare these 2 structures :

<client>
<name>bill</name>
<children>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
</children>
</client>

<client>
<name>bill</name>
<child>
<name>jon</name>
</child>
<child>
<name>joe</name>
</child>
</client>

Are there any advantages or disadvantages to using or not using the
element <children>?

We do not use attributes.


Thanks.
