Hello.

I want to export a xml, for example:

<?xml version="1.0" encoding="utf-8"?>
<item xmlns="http://sedici.unlp.edu.ar">
   <title>Agile managing of web requirements with WebSpec</title>
   <id>25670</id>
   <tipo>paper</tipo>
   <metadatos>
       <id>25</id>
       <valor>Pages 12</valor>
   </metadatos>
   <metadatos>
       <id>31</id>
       <valor>Jose Sanchez</valor>
   </metadatos>
   <metadatos>
       <id>64</id>
       <valor>UNET</valor>
   </metadatos>
</item>

My schema (XSD ) is:
<?xml version="1.0" encoding="utf-16"?>
<xsd:schema attributeFormDefault="unqualified" elementFormDefault="qualified" version="1.0" xmlns:xsd="http://www.w3.org/2001/XMLSchema">
<xsd:element name="item">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="title" type="xsd:string" />
<xsd:element name="id" type="xsd:int" />
<xsd:element name="tipo" type="xsd:string" />
<xsd:element name="metadatos">
<xsd:complexType>
<xsd:sequence>
<xsd:element name="id" type="xsd:int" />
<xsd:element name="valor" type="xsd:string" />
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>

Then, I create the following in WebRatio:
- XSD Provider
- XSD Resource

The following were generated virtual entities in my data model:

- Item (oid, title, ID, tipo)

- Item_metadata (oid, ID, valor)

My XSD is translated into Data Model elements is:
<Package id="pkg1" name="xSDProvider1" xmlns:gr="http://www.webratio.com/2006/WebML/Graph" gr:x="30" gr:y="575">
<Package id="pkg2" name="sedici" gr:x="0" gr:y="0">
<Entity id="ent9" name="item" duration="volatile" volatileStorage="database" xmlns:wrxsd="http://www.webratio.com/2012/WebML/WRXSD" wrxsd:provider="xsdp1" wrxsd:type="item[Element]" gr:x="0" gr:y="0">
<Attribute id="att31" name="oid" type="integer" key="true"/>
<Attribute id="att32" name="title" type="string" key="false" wrxsd:element="title"/>
<Attribute id="att33" name="ID" type="integer" key="false" wrxsd:element="id"/>
<Attribute id="att34" name="tipo" type="string" key="false" wrxsd:element="tipo"/>
</Entity>
<Entity id="ent10" name="item_metadatos" duration="volatile" volatileStorage="database" xmlns:wrxsd="http://www.webratio.com/2012/WebML/WRXSD" wrxsd:provider="xsdp1" wrxsd:type="item/metadatos[Element]" gr:x="210" gr:y="13">
<Attribute id="att35" name="oid" type="integer" key="true"/>
<Attribute id="att36" name="ID" type="integer" key="false" wrxsd:element="id"/>
<Attribute id="att37" name="valor" type="string" key="false" wrxsd:element="valor"/>
</Entity>
</Package>
</Package>

In my hypertext model, I added a "XML I/O" and a "Get XML"

When I try to export my XML, the web page does nothing.

The reference example I have is XML Schema Definition Support ( by Laura Cigardi ) http://www.webratio.com/learn/learningobject/XML-Schema-Definition-Support?link=oln1x.redirect&nav=16#!ajax=true

Any suggestions or examples with code, because I think I'm doing something wrong.

Regards,

Jose

Hi Jose,

it seems that you did everything correctly.

Check whether you configured properly the XML I/O operation.

Did you choose the "Export" mode?

Did you select the Entity to export?

In the article you mentioned there is a Script component that takes the XML resulting from the XML I/O operation and do something before passing it to the field of the form. Do you have the script of the Script component?

If you are getting an empty page, maybe the application raised an exception that can be found in the application logs. Just check in the web application folder under the WEB-INF/log directory and read through the RTXError.log file. You may find here which is exactly the problem.
