Detailed Description

Lightweight XML parser class.

The class provides a simplified interface for the TinyXML library focused on specific needs in scientific computing. It assumes that the XML data has a tree structure like:

 <Root>
   <Child>
      <SubChild>Text</SubChild>
      <SubChild attrib1="3.0" attrib2="0.14">
      ...
   </Child>
 ...
 </Root>
 

Member functions provided focus on the following specific tasks:

• crawling down in the tree,
• extracting the text field from an child element,
• extracting the attributes of an child element, copying them into an array.
