<h1><a name="description">DESCRIPTION</a></h1> |
| 56 |
|
|
<p>The <code>Whatpm::ContentChecker</code> Perl module contains two methods |
| 57 |
|
|
to validate DOM tree for its conformance to the markup language |
| 58 |
|
|
in use.</p> |
| 59 |
|
|
<p>This module is part of Whatpm, Perl Modules for |
| 60 |
|
|
Web Hypertext Application Technologies, which is a subproject |
| 61 |
|
|
of manakai.</p> |

|
|
<p>This module contains two static methods:</p> |
| 67 |
|
|
<dl> |

|
<dt><strong><a name="item_check_document">Whatpm::ContentChecker->check_document (<em>$document</em>, <em>$onerror</em>);</a></strong><br /> |
| 69 |
|
|
</dt> |
| 70 |
|
|
<dd> |
| 71 |
|
|
Checks a document, <em>$document</em>, and its descendant for their |
| 72 |
|
|
conformance. If there is an error or a warnign, then the |
| 73 |
|
|
<em>$onerror</em> <code>CODE</code> is invoked with named arguments same |
| 74 |
|
|
as ones for the method <a href="#item_check_element"><code>check_element</code></a>. |
| 75 |
|
|
</dd> |
| 76 |
|
|
<p></p> |
| 77 |

<dt><strong><a name="item_check_element">Whatpm::ContentChecker->check_element (<em>$element</em>, <em>$onerror</em>);</a></strong><br /> |
| 78 |
|
|
</dt> |
| 79 |
|
|
<dd> |
| 80 |
|
|
Checks an element, <em>$element</em>, and its descendant for their conformance. |
| 81 |
|
|
If there is an error or a warning, then the <em>$onerror</em> <code>CODE</code> |
| 82 |
|
|
is invoked with named arguments: |
| 83 |
|
|
</dd> |
| 84 |

<dl> |

<dt><strong><a name="item_level">level (Might be <code>undef</code>)</a></strong><br /> |
| 86 |
|
|
</dt> |
| 87 |
|
|
<dd> |
| 88 |
|
|
A string which describes the severity of the error or warning. |
| 89 |
|
