    How to validate an XML containing an inline schema with Powershell 5.1? - Stack Overflow

    programmeradmin3浏览0评论

    I created an XML with inline schema and wrote a Powershell script to validate my XML, but it was failing every time.

    Not sure whether the problem lies with my XML or with the validating script, I copied the inline-namespaced.xml example from Microsoft and my script said it was valid. My script used LINQ to XML. However, when I "invalidated" the XML by renaming the 'book' element to 'books' (which is not described in the schema), it still said it was valid (!). According to the answer to this question, LINQ to XML validates everything when the targetNamespace of the schema does NOT match the one of the document.

    So I modified my script to use XmlReader, which also fails to validate the basic example from Microsoft. It says: Line 2, Pos 2, Could not find schema information for the element 'catalog'. So, there is already a problem with the root element. Obviously, I'm doing something wrong, but what?

    inline-namespaced.xml:

    <?xml version="1.0"?>
<catalog xmlns:xsd="; xmlns:x="urn:book">
  <!-- START OF SCHEMA -->
  <xsd:schema targetNamespace="urn:book">

    • Proshell is written in Net library so you can always check the c# online documentation. See XMLReader Settings Valiation flags : learn.microsoft/en-us/dotnet/api/… – jdweng Commented Feb 17 at 22:30
    • @jdweng, I do use the XmlReader ValidationFlags as in the link you provided. I even tried the inlineSchema.xml from the link and I got the exact same errors as described in the link. So my question remains: how to solve the first error "Could not find schema information for the element 'root'" (or 'catalog' as the root element is called in the original example)? – Wim Commented 2 days ago
    • I'm not seeing any errors when changing "book to books" using another tools. Only seeing warning "could not find books in schema". Did you see in link the option for ReportValidationWarnings? – jdweng Commented 2 days ago
    • The code that I posted contains $settings.ValidationFlags = [System.Xml.Schema.XmlSchemaValidationFlags]::ProcessInlineSchema -bor [System.Xml.Schema.XmlSchemaValidationFlags]::ReportValidationWarnings so yes, ReportValidationWarnings is added as a flag. But fet the book to books mod. That was when I used LINQ to XML and it said that both versions were valid which imho is not correct. That's why I switched to XmlReader. I assume (dangerous, I know) that Microsoft's example XML is correct, but I fail to validate that XML with the above script and don't understand why. – Wim Commented 2 days ago
    • I did not find any errors. Did you check the xml with an online checker to see if there are errors? – jdweng Commented 2 days ago

    Your XML is complicated due to the presence of a namespace.

    Please try the following solution that has two XSD files instead of one!!!

    I tested it as-is, i.e. without PowerShell. You can try it in c# and LINQ to XML.

    XML
