We modified Zend_Config_Ini to allow the use of numeric keys. I
wonder if there's something similar we can do here?
I've made a small patch if you're interested:-
Zend/Config/Xml.php

--- Xml.php (revision 6921)
+++ Xml.php (working copy)
@@ -137,10 +137,18 @@
if (count($xmlObject->children())) {
foreach ($xmlObject->children() as $key => $value) {
if ($value->children()) {
- $config[$key] = $this->_toArray($value);

} else {
- $config[$key] = (string) $value;

Essentially it looks for existing keys whilst the array is being built
- if the key already exists it transforms the value into a numeric
array instead of a string value.
I tested it with the following config:-
<root>
<foo>
<bar>Item 1</bar>
<bar>Item 2</bar>
<bar>Item 3</bar>
<bar>Item 4</bar>
<bar>Item 5</bar>
<item>3</item>
<item>2</item>
<mail>
<name>My name</name>
</mail>
</foo>
</root>
...and it gives the following output:-
Zend_Config Object
(
[_allowModifications:protected] =>
[_index:protected] => 0
[_count:protected] => 3
[_data:protected] => Array
(
[bar] => Zend_Config Object
(
[_allowModifications:protected] =>
[_index:protected] => 0
[_count:protected] => 5
[_data:protected] => Array
(
[0] => Item 1
[1] => Item 2
[2] => Item 3
[3] => Item 4
[4] => Item 5
)
[_loadedSection:protected] =>
[_extends:protected] => Array
(
)
)
[item] => Zend_Config Object
(
[_allowModifications:protected] =>
[_index:protected] => 0
[_count:protected] => 2
[_data:protected] => Array
(
[0] => 3
[1] => 2
)
[_loadedSection:protected] =>
[_extends:protected] => Array
(
)
)
[mail] => Zend_Config Object
(
[_allowModifications:protected] =>
[_index:protected] => 0
[_count:protected] => 1
[_data:protected] => Array
(
[name] => My name
)
[_loadedSection:protected] =>
[_extends:protected] => Array
(
)
)
)
[_loadedSection:protected] =>
[_extends:protected] => Array
(
)
)
Hope this is helpful
There are several mismatches between INI and XML formats, so it's no
surprise that we must treat each a bit differently. How would having
multiple values work in INI, or would we not support this?
Numeric tag names make illegal XML, so we already have functionality
in
Zend_Config_Ini that is not supported with Zend_Config_Xml.
In principle, I have no objection to adding such support.
Thanks, Rob!
