Feature-type Element

Every feature mapping rule may (this is an optional element) contain one feature-type element, the contents of this element is an expression sequence whose value becomes the feature type of the constructed FME feature. This is represented in xfMap by the <feature-type> element:

<feature-type>
	<!-- the content is some expression sequence -->		
</feature-type>

Note: The feature type for the FME feature that is under construction is set only by the first activated feature mapping rule that contains a <feature-type> element. Subsequent feature mapping rules with <feature-type> elements for the same FME feature under construction are ignored by the XML Reader.

The following xfMap document, feature_type.xmp, contains a mapping rule Rp that matches a <point> element from the input points1.xml document. Here Rp has a <feature-type> element that instructs the XML Reader to set the feature type for the FME feature that is under construction.

feature_type.xmp

<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE xfMap SYSTEM "xfMap.dtd">
<xfMap>	 
	<feature-map>
		<!-- Call this mapping rule Rp -->
		<mapping match="point">	    
			<feature-type>
				<!-- the feature-type element has as its
					contents an xfMap expression sequence.
					An expression sequence is a sequence
					of expression elements. -->
				<extract expr="@name"/>
				<literal expr="_"/>
				<extract expr="@num"/>
			</feature-type>
		</mapping>
	</feature-map>					   
</xfMap>

When the points1.xml and the above feature_type.xmp documents are fed into the XML Reader, the following FME features are constructed:

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Feature Type: myPoint_0'
Attribute: xml_type' has value xml_no_geom'
Geometry Type: Unknown (0)
==============================================================
++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++
Feature Type: myPoint_1'
