| // This sample program which invokes the DOMParser to build a DOM tree for |
| // the specified input file. It then walks the tree, and prints out the data |
| // as an XML file. |
| // |
| // The parameters are: |
| // |
| // [-?] - Show usage and exit |
| // [-v] - Do validation |
| // [-NoEscape] - Don't escape characters like '<' or '&'. |
| // filename - The path to the XML file to parse |
