"Tool functionality is good."
Extensible Markup Language (XML) schema express shared vocabulary and allows machines to execute rules made by human beings.
They provide a method of defining the structure, semantics, and content of XML documents.
A Well-Formed and well-structured XML document means that it has proper XML syntax and rules.
A valid XML document is "Exquisite", and also adapts to the rules and regulations of a "Document Type Definition (DTD)", XML Schema, or other types of schema that determine the construction of an XML document.
The problem is that errors may be introduced when creating XML documents.
Handling large projects or a large number of files will increase the probability of errors.
Identifying and resolving errors in a project is time-consuming and frustrating sometimes.
Fortunately, the features provided by this XML XSD validator make it quicker and easier to recognize mistakes.
This XSD validator tool provides the latest version of the Java API for XML Processing to verify files against XML Schemas.
By using this online xml schema validator and checker, you can check the validity of XML against XSD quite easily.
All you have to do is just paste the XML and click on “Check XSD validity” button.
In XML Schema Definition (XSD), we can verify:
A simple element in XSD consists of the text of various data types, like Boolean value, date, string, or any custom type.
It can be restricted to maintain the consistency of values. A complex element with specific element values is called an attribute.
When specifying attributes, an element is considered to be a complex element. When only one element is needed to be validated, we can validate it under XSD tag xs:simpleType.
In this case, the validations are more specific to the type of a specific element.
However, when a group or series of elements are to be verified, we can specify it under xs:complexType.
Here, XSD verifies all child components under a parent element, sequentially.
For any type of XSD file, the XML declaration statement, together with namespace information, is required.
An extensible markup language namespace is a collection of names that can be used as elements or attributes in XML files.
In order to avoid conflicts between elements with the same name, it uniquely defines the names of elements on the network.
We can validate the outermost element, child elements, sub-child elements, event type, and event timing through this sort of process.
