## Non-Compliant Code Examples{% #non-compliant-code-examples %}

```java
public class TestClass {

    public void parseXML(InputStream input) throws XMLStreamException {

        XMLInputFactory factory = XMLInputFactory.newFactory();
        factory.setProperty("aproperty", false);
        XMLStreamReader reader = factory.createXMLStreamReader(input);
        factory.setProperty("anotherproperty", false);
    }
}
```

## Compliant Code Examples{% #compliant-code-examples %}

```java

        factory.setProperty(XMLInputFactory.SUPPORT_DTD, false);
        factory.setProperty("anotherproperty", false);
        XMLStreamReader reader = factory.createXMLStreamReader(input);
    }
}
```

```java
