<title>Web Services for Tcl (aka tclws): Dictionary Representation of XML Arrays</title>

<body>
<p>
XML arrays are represented in dictionary format as a list of values.
Lets consider what this looks like for a
<a href="#SimpleTypeArray">simple type</a> and for a
<a href="#ComplexTypeArray">complex type</a>;.
</p>
<p><a name="SimpleTypeArray"></a>
</p><h3>Array of Simple Type</h3>
<p>
Lets assume we have an element with the following definition:
</p><pre class="verbatim"> <xs:element minOccurs="0" maxOccurs="unbounded" name="Primes" type="xs:integer" />
</pre>
Lets also assume that we will have that element in our dictionary with
the first four prime numbers, thus the dictionary representation for
that element would look like:
<pre class="verbatim"> Primes {2 3 5 7}
</pre>
Or, if we have are using attributes (i.e. parseInAttr and/or genOutAttr are set), it would look like:
<pre class="verbatim"> Primes {{} {2 3 5 7}}
</pre>
<p></p>
<p><a name="ComplexTypeArray"></a>
</p><h3>Array of Complex Type</h3>
<p>
Lets assume we have the type definition:
</p><pre class="verbatim"><xs:element name="Person">
<xs:complexType>
<xs:sequence>
<xs:element name="FristName" type="xs:string"/>
<xs:element name="LastName" type="xs:integer"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</pre>
Lets assume we have the following definition:
<pre class="verbatim"> <xs:element minOccurs="0" maxOccurs="unbounded" name="Attendees" type="Person" />
</pre>
Now lets assume the following people are are attending:
<ul>
<li> John Doe </li>
<li> Jane Doe </li>
</ul>
Thus the dictionary representation for that element would look like:
<pre class="verbatim"> Attendees {
{FirstName {John} LastName {Doe}}
{FirstName {Jane} LastName {Doe}}
}
</pre>
Or, if we have are using attributes (i.e. parseInAttr and/or genOutAttr are set), it would look like:
<pre class="verbatim"> Attendees {
{{} {FirstName {{} {John}} LastName {{} {Doe}}}}
{{} {FirstName {{} {Jane}} LastName {{} {Doe}}}}
}
</pre>
<p></p>
</div>
</body></html>
