XML catalog

We can extend this further into XML files where we may not want to display the complete record, but just certain fields. Consider the following product catalog:

<products><product> 
<name>drill</name> 
<price>99</price> 
<stock>5</stock> 
</product> 
 
<product> 
<name>hammer</name> 
<price>10</price> 
<stock>50</stock> 
</product> 
 
<product> 
<name>screwdriver</name> 
<price>5</price> 
<stock>51</stock> 
</product> 
 
<product> 
<name>table saw</name> 
<price>1099.99</price> 
<stock>5</stock> 
</product> </products>

Logically, each record is delimited as before with the empty line. Each field though is a little more detailed and we need to use the delimiter as follows: FS="[><]". We define either the opening or closing angle bracket as the field delimiter. ...
