#6 Fix for bug 891149

[Lexi Baugher]

When the response contains a struct with a nested
document/literal array. SOAP::Deserializer flattens the
array into a single scalar whose value is the last
element of the array (because it maps all the child
nodes into a hash, keyed off the name of the child nodes).

href="http://sourceforge.net/tracker/index.php?func=detail&aid=891149&group_id=66000&atid=513017">Bug
891149</a> has one example.

This patch modifies the struct element parsing so that
repeated child elements are turned into an array. The
result is that this document:

&lt;getFooResponse xmlns="http://example.com/v1">
&nbsp;&nbsp; &lt;getFooReturn>
&nbsp;&nbsp;&nbsp;&nbsp; &lt;complexFoo>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp; &lt;id>100&lt;/id>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&lt;arrayFoo>one&lt;/arrayFoo>
&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;
&lt;arrayFoo>two&lt;/arrayFoo>
&nbsp;&nbsp;&nbsp;&nbsp; &lt;/complexFoo>
&nbsp;&nbsp; &lt;/getFooReturn>
&lt;/getFooResponse>

would now be parsed to a structure like this:

$VAR1 = {
'complexFoo' => {
'arrayFoo' => [
'one',
'two'
],
'id' => 100
}
};

(The existing code creates the following structure)

$VAR1 = {
'complexFoo' => {
'arrayFoo' =>'one',
'id' => 100
}
};

The patch is against the latest CVS sources.
