Question

Looking for readable example use of Omni Xml package.

the documentation now is 2 examples, for loading and writing, nothing about reading, nor iterating.

could you provide a simple reading Xml ,example of one repeatable property

such as

<root>
<value p1=1></value>
<value p1=2 p2='32432'/>
<value p1=3 p3='fdsf'><other></other></value>
</root>

how to iterate over all the values and get the p1 property.
