Validate XML with XSD schema

[Piotr D]

Hi,
Do you know any way to validate XML file with XSD schema directly in Xbase ++ program? Maybe there is some library or ActiveX?

Regards
Piotr

Hello Piotr

The topic is very interesting. Unfortunately I can't help you. I am also looking for such a solution. An XML validator with XSD. I only find examples in other languages ​​like C#, in .Net, in Visual Basic, but not Xbase++

Although it is not a solution, but I will attach an example in C# so that anyone who wants to help us can better understand what we are looking for.

Cordial greetings.

Code: Select all

 using System;
using System.Xml;
using System.Xml.Schema;

class XmlSchemaSetExample
{
    static void Main()
    {
        XmlReaderSettings booksSettings = new XmlReaderSettings();
        booksSettings.Schemas.Add("http://www.contoso.com/books", "books.xsd");
        booksSettings.ValidationType = ValidationType.Schema;
        booksSettings.ValidationEventHandler += new ValidationEventHandler(booksSettingsValidationEventHandler);

        XmlReader books = XmlReader.Create("books.xml", booksSettings);

        while (books.Read()) { }
    }

    static void booksSettingsValidationEventHandler(object sender, ValidationEventArgs e)
    {
        if (e.Severity == XmlSeverityType.Warning)
        {
            Console.Write("WARNING: ");
            Console.WriteLine(e.Message);
        }
        else if (e.Severity == XmlSeverityType.Error)
        {
            Console.Write("ERROR: ");
            Console.WriteLine(e.Message);
        }
    }
}  [code/]

Dear Diego,
unable to find a library for Xbase to handle thisk task, I asked a friend to write a C# program. There are ready-made functions in C# to handle this task. The ready program is called by passing the XML file and the address of the XSD file as parameters. I get the validation effect back.

Dear Piotr,

I'm glad you found a solution. I use Xbase++ 2.0 and I notice that it has an XML handling library. But, I do not find anything specific to validate an XML visus XSD, this being so important today.

Maybe it does, and it has another name...

Best regards.

Sorry to be late to party, but in case there is no quick solution to get c# program there is almost always open source solution for that via command line:

Part of project libxml2 is also lint (syntax checker) for

Project:

https://gitlab.gnome.org/GNOME/libxml2/-/wikis/home

xmllint manpage:

https://gnome.pages.gitlab.gnome.org/li ... llint.html

call sample:

xmllint --schema yourxsd.xsd yourxml.xml

catch stdout and analyse it

You can get project and compile on own, or get precompiled binaries at one of mainteiners webpage

Excellent, Klaus, thank you very much.

Although, I would like to validate an XML via an XSD, via Xbase code. It is the only way that my work would look good, since I must do the process in my system.

Alaska Software offers many XML functions, but I haven't found one to validate yet.

Hi,

This should be possible with MSXML xml parser. This is an active-x component, which can be used in Xbase++.

Search in Google for

validation xml with xsd schema vbscript

. There are some samples in VBscript, which should be rather easy to convert.

[Diego Euri Almanzar]

good alternative, Chris.

Thanks a lot. Although, I understand that Alaska software, in all those new functions of its library for XML, must have the solution. I did not send an email to them, because in July the subscription expired.

I thank you again.

Hi Diego,

No, the solution won't be in Xbase++.
