questions on XML::Simple

[Jeff]

I used the XML::Simple module to read some xml, which works great.

But when I write it back out with XMLout.. it's changed.

For example the input that looks like this:

<Summary>
<TotalOrders>1</TotalOrders>
<TotalLineItems>4</TotalLineItems>
<TotalQuantity>158</TotalQuantity>
</Summary>

ends up looking like this:

<Summary TotalLineItems="4" TotalOrders="1" TotalQuantity="158" />


Is it possible to have it written out in the same format it was read
from? Is there another module that would do this?

Thanks.

See the NoAttr option.

There are lots of other XML modules (XML:arser, XML::LibXML, the
XML::SAX modules, XML:OM, ...) but if XML::Simple does what you need
it's probably better to stick with what you have. If your XML really is
always going to be as simple as you say you could try XML::Tiny, but
make sure you carefully read the list of what it does and doesn't
support.

See the NoAttr option.

Use ForceArray when doing XMLin. I think this would be better than
using NoAttr on XMLout. With ForceArray things that were attributes on the
way in are still attributes on the way out, while tags on the way in are
tags on the way out--rather than turning everything into tags.

No, because XML::Simple doesn't keep all the necessary information.

Agreed. But it will still not preserve the order of elements:

<Summary>
<TotalLineItems>4</TotalLineItems>
<TotalOrders>1</TotalOrders>
<TotalQuantity>158</TotalQuantity>
</Summary>
