Oxygen XML Forum

I downloaded the GPX schema file from

http://www.topografix.com/gpx.asp

... using Internet Explorer's "Save Target As..."

This gave me file gpx.xml which starts as follows...

<?xml version="1.0" encoding="utf-8"?>
<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema"
xmlns="http://www.topografix.com/GPX/1/1"
targetNamespace="http://www.topografix.com/GPX/1/1"
elementFormDefault="qualified">

When I open this file in Oxygen and click the 'Validate Document' button, I get error

Description: E cvc-elt.1: Cannot find the declaration of element 'xsd:schema'.

The strange thing is that when I create a new file in Oxygen and declare it to be an XML Schema file, then copy/paste the complete content of gpx.xml into the new file and press 'Validate', it validates without any complaint. The two files are byte-for-byte the same.

Is it the .xml file extension?

Hi Johan,

When you open an XML file oXygen opens that in the XML editor. If you open an XSD file oXygen opens that in the XML Schema editor. You can see also that there are different actions for these editors (although there are also common actions). The validate action in these two editors is different.

Thanks for this clarification George.

Is there a way to make the choice for a specific editor, schema-editor or xml-editor, explicit?

Or is it the rule that schema files are required to have the .xsd extenstion?

Hi Johan,

In oXygen 6.2 there will be an entry in the project contextual menu called "Open As..." that will allow manually selecting the editor to be used for opening the selected file.

Best Regards,
George
