Hello all,
I am writing an OCCI implementation that accepts OVF for the
Venus-C research project. This implementation parses OVF and
uses the extracted informatios to build the input fir the
appropriate OCA api.
/compute works using OCA allocate(), now I am working on
/compute/[id] that will use OCA info(). This call returns an XML
that I have to translate into an OVF.
I choosed to parse this XML using xjc to compile xsd definitions
into Java classes.
I downloaded the xsd from the hyperlink in the XML-RPC page, but
the definition for VMs (i.e. the answer of the info() OCA api)
is too coares, and I need to parse at least some of the tags
inside the <TEMPLATE /> tag to get finer grained informations.
So I have to change the xsd I downloaded.
This lead to this question: May I assume that tag order is fixed
inside <TEMPLATE /> ? so that the content may be defined by a
<xs:sequence /> ?
And does this hold even for the content of <DISK>, <NIC> and
<OS>?
Common sense says that Ruby should not execute its instruction
out of order, so the order is fixed and some elements may or may
not appear, but the order should not change. Can you confirm
this ?
Thank you in advance.
