Any Element

---

An element in a sequence can be declared using the xsd:any keyword to indicate that an element of any type can be present in that position. An example of this type of construct is as follows:

	<xsd:complexType name="SeqWithAny">
 
	   <xsd:sequence>
 
	      <xsd:element name="a" type="xsd:string"/>
 
	      <xsd:any processContents="lax"/>
 
	   </xsd:sequence>
 
	</xsd:complexType>
 

In this case, the element a is followed by another element with any name and of any type. The processContents="lax" attribute tells a schema processor to do lax validation processing on the element in this position - something that is of no concern to the XBinder compiler.

The generated C type definition for this type is as follows:

	typedef struct SeqWithAny {
 
	   OSXMLSTRING a;
 
	   OSXMLSTRING _any;
 
	} SeqWithAny;
 

C++ is similar except that the standard class pattern is used:

	class SeqWithAny : public OSRTBaseType {
 
	public:
 
		OSXMLStringClass a;
 
		OSXMLStringClass _any;
 
	...
 
	} ;
 

In this case, the compiler has inserted an OSXMLSTRING typed element to represent the any field. This contains a UTF-8 character string containing the complete XML text string value.

An example code snippet that could be used to populate a C variable of this type for encoding is as follows:

	const OSUTF8CHAR* anyData = (const OSUTF8CHAR*)
 
		"<anyData>this is test data</anyData>";
 

 
	SeqWithAny testSeq;
 

 
	testSeq.a.value = (const OSUTF8CHAR*)"test string";
 
	testSeq._any.value = anyData;
 
	...
