O exemplo usa o arquivo , items.xml
, como entrada.
<?xml version="1.0"?>
<!-- This is a sample XML document -->
<!DOCTYPE Items [<!ENTITY number "123">]>
<Items>
<Item>Test with an entity: &number;</Item>
<Item>test with a child element <more/> stuff</Item>
<Item>test with a CDATA section <![CDATA[<456>]]> def</Item>
<Item>Test with a char entity: A</Item>
<!-- Fourteen chars in this element.-->
<Item>1234567890ABCD</Item>
</Items>
