2.8. Configuring the Fixed-Length Reader


  1. To configure the fixed-length reader, modify the http://www.milyn.org/xsd/smooks/fixed-length-1.3.xsd configuration namespace as shown below:
    <?xml version="1.0"?>
    <smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" xmlns:fl="http://www.milyn.org/xsd/smooks/fixed-length-1.3.xsd">
     
        <!--
        Configure the Fixed length to parse the message into a stream of SAX events.
        -->
        <fl:reader fields="firstname[10],lastname[10],gender[1],age[2],country[2]" skipLines="1" />
     
    </smooks-resource-list>
    
    
    Here is an example input file:
    #HEADER
    Tom       Fennelly  M 21 IE
    Maurice  Zeijen     M 27 NL
    
    Here is the event stream that will be generated:
    
    <set>
        <record>
            <firstname>Tom</firstname>
            <lastname>Fennelly</lastname>
            <gender>M</gender>
            <age>21</age>
            <country>IE</country>
        </record>
        <record>
            <firstname>Maurice</firstname>
            <lastname>Zeijen</lastname>
            <gender>M</gender>
            <age>27</age>
            <country>NL</country>
        </record>
    </set>
    
    
  2. Define the string manipulation functions as shown below:
    
    <?xml version="1.0"?>
    <smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" xmlns:fl="http://www.milyn.org/xsd/smooks/fixed-length-1.3.xsd">
     
        <!--
        Configure the fixed length reader to parse the message into a stream of SAX events.
        -->
        <fl:reader fields="firstname[10]?trim,lastname[10]trim.capitalize,gender[1],age[2],country[2]" skipLines="1" />
     
    </smooks-resource-list>
    
    
  3. You can also ignore these fields if you choose:
    
    <?xml version="1.0"?>
    <smooks-resource-list xmlns="http://www.milyn.org/xsd/smooks-1.1.xsd" xmlns:fl="http://www.milyn.org/xsd/smooks/fixed-length-1.3.xsd">
     
        <fl:reader fields="firstname,$ignore$[2],age,$ignore$[10]" />
     
    </smooks-resource-list>
