This tool allows you to validate that a XML conforms to the definition described by a XML Schema (XSD).
Fill in the editors below and it will automatically check if your XML conforms to XSD.
You can see the user guide to help you to use this online XML Validator.
It is very simple to validate your xml:
Step 1: You must fill "XML" editor. You can Drag and drop a XML file, click on "Browse a XML file" or directly type in the editor.
Step 2: It is analogous to step 1 (except that it concerns the "XML Schema" editor).
Step 3: As soon as the editors are filled, the tool checks if the XML conforms to the XSD. If errors are detected then they are displayed below the editors, else a success message is displayed.
This Online XML Schema Validator tool allows you to validate that your XML conforms to the specified schema.

The XML Schema definition language (XSD) allows to define the structure and data types for XML documents. It contains a set of rules to which an XML document must conform in order to be valid. It is the current standard schema language, it is a recommendation of the World Wide Web Consortium (W3C). It is an alternative to Document type definition (DTD).
XML Schema can be used by developers to check XML document, for example to verify a SOAP response. If the XML document does not conform to the XML schema, the SOAP response is wrong.
XML Schema can be complicated to understand and use for a novice (especially for a non-developer), the spec is very long. The XML schema generators from xml can help to create a Schema XML.
XML Schema uses XML syntax, a XSD is a XML document! This avoids having to use another format. XSD Example
<?xml version="1.0"?> <xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"> <xs:element name="book"> <xs:complexType> <xs:sequence> <xs:element name="author" type="xs:string"/> <xs:element name="title" type="xs:string"/> <xs:element name="price" type="xs:float"/> </xs:sequence> </xs:complexType> </xs:element> </xs:schema>
<book> <author>Isaac Asimov</author> <title>I, Robot</title> <price>10</price> </book>
XSD supports several primitive data types: boolean, string, decimal, float, double, date, dateTime, base64Binary, ... Then, it is possible to create complex types.
