/** |
|
84 |
* <p> |
|
85 |
* This is a pipeline component which performs XInclude handling, according to the |
|
86 |
* W3C specification for XML Inclusions. |
|
87 |
* </p> |
|
88 |
* <p> |
|
89 |
* This component analyzes each event in the pipeline, looking for <include> |
|
90 |
* elements. An <include> element is one which has a namespace of |
|
91 |
* <code>http://www.w3.org/2001/XInclude</code> and a localname of <code>include</code>. |
|
92 |
* When it finds an <include> element, it attempts to include the file specified |
|
93 |
* in the <code>href</code> attribute of the element. If inclusion succeeds, all |
|
94 |
* children of the <include> element are ignored (with the exception of |
|
95 |
* checking for invalid children as outlined in the specification). If the inclusion |
|
96 |
* fails, the <fallback> child of the <include> element is processed. |
|
97 |
* </p> |
|
98 |
* <p> |
|
99 |
* See the <a href="http://www.w3.org/TR/xinclude/">XInclude specification</a> for |
|
100 |
* more information on how XInclude is to be used. |
|
101 |
* </p> |
|
102 |
* <p> |
|
103 |
* This component requires the following features and properties from the |
|
104 |
* component manager that uses it: |
|
105 |
* <ul> |
|
106 |
* <li>http://xml.org/sax/features/allow-dtd-events-after-endDTD</li> |
|
107 |
* <li>http://apache.org/xml/properties/internal/error-reporter</li> |
|
108 |
* <li>http://apache.org/xml/properties/internal/entity-resolver</li> |
|
109 |
* </ul> |
|
110 |
* Optional property: |
|
111 |
* <ul> |
|
112 |
* <li>http://apache.org/xml/properties/input-buffer-size</li> |
|
113 |
* </ul> |
|
114 |
* |
|
115 |
* Furthermore, the <code>NamespaceContext</code> used in the pipeline is required |
|
116 |
* to be an instance of <code>XIncludeNamespaceSupport</code>. |
|
117 |
* </p> |
|
118 |
* <p> |
|
119 |
* Currently, this implementation has only partial support for the XInclude specification. |
|
120 |
* Specifically, it is missing support for XPointer document fragments. Thus, only whole |
|
121 |
* documents can be included using this component in the pipeline. |
|
122 |
* </p> |
