download XSD with all imports - xsd

Question

I use gml (3.1.1) XSDs in XSD for my application. I want to download all gml XSDs in version 3.1.1 in for example zip file. In other words: base xsd is here and I want to download this XSD with all imports in zip file or something like zip file. Is there any application which supports that?
I've found this downloader but it doesn't works for me (I think that this application is not supporting relative paths in imports which occurs in gml.xsd 3.1.1). Any ideas?

Answer 1

QTAssistant's XSR (I am associated with it) has an easy to use function that allows one to automatically import and refactor XSD content as local files from all sorts of sources. In the process it'll update schema location references, etc.
I've made a simple screen capture of the steps involved in achieving a task like this which should demonstrate its usability.

Answer 2

Based on the solution of mschwehl, I made an improved class to achieve the fetch. It suited well with the question. See https://github.com/mfalaize/schema-fetcher

Answer 3

You can achieve this using SOAP UI.
Follow these steps :
Create a project using the WSDL.
Choose your interface and open in interface viewer.
Navigate to the tab 'WSDL Content'.
Use the last icon under the tab 'WSDL Content' : 'Export the entire WSDL and included/imported files to a local directory'.
select the folder where you want the XSDs to be exported to.
Note: SOAPUI will remove all relative paths and will save all XSDs to the same folder.

Answer 5

I created a python tool to recursively download XSDs with relative paths in import tags (eg: <import schemaLocation="../../../../abc)
https://github.com/n-a-t-e/xsd_download
After downloading the schema you can use xmllint to validate an XML document

Answer 6

I am using org.apache.xmlbeans.impl.tool.SchemaResourceManager from the xmlbeans project. This class is quick and easy to use.
for example:
SchemaResourceManager manager = new SchemaResourceManager(new File(dir));
manager.process(schemaUris, emptyArray(), false, true, true);
manager.writeCache();
This class has a main method that documents the different options available.
