How to Generate XML from XSD
Paste or upload XSD
Enter your XSD schema content in the input area or upload an .xsd file from your computer.
Click Convert
Press the Convert button to analyze the schema and generate a sample XML document.
Review the output
Examine the generated XML instance. All elements, attributes, and namespaces from your schema will be represented.
Customize and use
Copy or download the XML, then customize the sample values for your specific use case while maintaining schema compliance.
Understanding XSD to XML Conversion
What Happens During Conversion?
When you convert an XSD schema to XML, the tool performs several important operations:
- Schema Parsing: The XSD is parsed to identify all element and type definitions
- Root Element Detection: The converter identifies the root element declaration
- Type Resolution: Complex and simple types are resolved to determine element structure
- Instance Generation: XML elements are created with appropriate sample values
- Namespace Handling: XML namespaces are properly declared and prefixed
Common Use Cases
- •API Development: Generate sample request/response XML for SOAP web services
- •Testing: Create test fixtures for XML parsers and validators
- •Documentation: Generate example XML for technical documentation
- •Learning: Understand complex XSD schemas by seeing the resulting XML structure
- •Data Migration: Create template files for data import/export processes
XSD Type to XML Value Mapping
Our converter generates appropriate sample values based on the XSD data type. Here's how different types are handled:
| XSD Type | Sample Value Generated | Notes |
|---|---|---|
| xs:string | "sample" | Generic string placeholder |
| xs:integer | 0 | Whole number without decimals |
| xs:decimal | 0.00 | Number with decimal precision |
| xs:boolean | true | true or false values |
| xs:date | 2024-01-15 | ISO 8601 date format |
| xs:dateTime | 2024-01-15T10:30:00Z | ISO 8601 with time and timezone |
| xs:anyURI | https://example.com | Valid URI format |
| xs:base64Binary | SGVsbG8= | Base64 encoded sample |
Example: XSD to XML Conversion
Input XSD Schema
<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema">
<xs:element name="order">
<xs:complexType>
<xs:sequence>
<xs:element name="orderId" type="xs:string"/>
<xs:element name="customer">
<xs:complexType>
<xs:sequence>
<xs:element name="name" type="xs:string"/>
<xs:element name="email" type="xs:string"/>
</xs:sequence>
<xs:attribute name="id" type="xs:integer"/>
</xs:complexType>
</xs:element>
<xs:element name="items">
<xs:complexType>
<xs:sequence>
<xs:element name="item" maxOccurs="unbounded">
<xs:complexType>
<xs:sequence>
<xs:element name="productId" type="xs:string"/>
<xs:element name="quantity" type="xs:integer"/>
<xs:element name="price" type="xs:decimal"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:sequence>
</xs:complexType>
</xs:element>
<xs:element name="orderDate" type="xs:date"/>
<xs:element name="shipped" type="xs:boolean"/>
</xs:sequence>
</xs:complexType>
</xs:element>
</xs:schema>Generated XML Output
<?xml version="1.0" encoding="UTF-8"?>
<order>
<orderId>sample</orderId>
<customer id="0">
<name>sample</name>
<email>sample</email>
</customer>
<items>
<item>
<productId>sample</productId>
<quantity>0</quantity>
<price>0.00</price>
</item>
<item>
<productId>sample</productId>
<quantity>0</quantity>
<price>0.00</price>
</item>
</items>
<orderDate>2024-01-15</orderDate>
<shipped>true</shipped>
</order>Notice how the converter handles nested complex types, attributes, repeating elements (maxOccurs), and generates appropriate sample values for each data type.
Tips for Better Results
Validate Your XSD First
Ensure your XSD schema is valid before conversion. Use our XML Validator to check for syntax errors that might prevent successful conversion.
Handle Imports Separately
If your XSD uses xs:import or xs:include to reference other schemas, you may need to inline those definitions for the converter to process the complete structure.
Customize After Generation
The generated XML uses placeholder values. Replace them with realistic data for testing, then validate against the original XSD using our validator.
