| 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. |
| 7 | </p><p> |
| 8 | It is included in <span class="application">libxml2</span>. |
