Hi,

(it may be a stupid question, sorry)

How can I read the node value "DBConnection" from
<Performers>
<Performer>DBConnection</Performer>
</Performers>

Given is the xsd (from XPDL2.1):
...
<xsd:element name="Performer">
<xsd:annotation>
<xsd:documentation>A String or Expression designating the Performer</xsd:documentation>
</xsd:annotation>
<xsd:complexType>
<xsd:simpleContent>
<xsd:extension base="xsd:string">
<xsd:anyAttribute namespace="##other" processContents="lax"/>
</xsd:extension>
</xsd:simpleContent>
</xsd:complexType>
</xsd:element>

Any help would be great!

Hi

We don't use XSD for modeling; we use Ecore, so perform the XSD to Ecore
conversion to Ecore to see what your converted XSD is like. Then you'll
know what you can access.

Hi Ed,
thanks. The ecore is below and it only gives access to the attributes.
If the input is:
<Performer Value="DBConnection"></Performer>
...I can pick it.

But is there a way to handle this input?
<Performer>DBConnection</Performer>

Kind regards
Gerhard

class PerformerType
{
attribute Value : _'ecore.xml.type'::String[?] { ordered }
{
annotation _'<some link>'
(
name = ':0',
kind = 'simple'
);
}
attribute Relationship : _'ecore.xml.type'::String[?] { ordered }
{
annotation _'<some link>'
(
kind = 'attribute',
name = 'Relationship'
);
}
attribute AnyAttribute : ecore::EFeatureMapEntry[*] { ordered !unique }
{
annotation _'<some link>'
(
kind = 'attributeWildcard',
wildcards = '##other',
name = ':2',
processing = 'lax'
);
}
annotation _'<some link>'
(
name = 'Performer_._type',
kind = 'simple'
);
}

Hi

The EMF project provides a variety of capabilities to read a variety of
different XML styles specifically to help those with non-standard or
legacy XML requirements. I do not need them, so I can only refer you to
the EMF book that I would consult if I needed to use them.

Hi Ed,

concerning my XML example: its neither legacy nor special, it's frequently used.

(I didn't find it in the ATL manual, shouldn't I?)

Could you please tell me what you mean by "the EMF book"?

Regards Gerhard.
