| MDT 2003 John Fleck | 2ae05c7 | 2003-07-23 01:43:53 +0000 | [diff] [blame] | 2 | The xmllint program parses one or more XML files, specified on the |
| 3 | command line as <i class="replaceable"><tt>xmlfile</tt></i>. It prints various |
| 4 | types of output, depending upon the options selected. It is useful for |
| 5 | detecting errors both in <span class="acronym">XML</span> code and in the |
| 6 | <span class="acronym">XML</span> parser itself. |
