将alt值​​添加到div中的所有锚标记

Question

我正在尝试将alt值​​添加到特定div中的所有锚标记。 我需要遍历div并找到锚标记并添加alt值。 结构如下所示

<div id="ctl00_MenuTreeView" style="font-size:11px;"     onadaptedselectednodechanged="OnNodeSelected">
<table cellspacing="0" cellpadding="0" style="border-width:0;">
<tbody>
<tr>
<td>
<td class="TreeViewNode ctl00_MenuTreeView_2 ctl00_MenuTreeView_6"     onmouseout="TreeView_UnhoverNode(this)"     onmouseover="TreeView_HoverNode(ctl00_MenuTreeView_Data, this)">
<a id="ctl00_MenuTreeViewt0" class="ctl00_MenuTreeView_0 TreeViewNode     ctl00_MenuTreeView_1 ctl00_MenuTreeView_5" style="border-style:none;font-size:1em;"     title="Home Page" onclick="TreeView_SelectNode(ctl00_MenuTreeView_Data,     this,'ctl00_MenuTreeViewt0');"     href="javascript:__doPostBack('ctl00$MenuTreeView','s/wotc/Default.aspx')">Home</a>
</td>
</tr>
</tbody>
</table>
<table cellspacing="0" cellpadding="0" style="border-width:0;">
<table cellspacing="0" cellpadding="0" style="border-width:0;">
<table cellspacing="0" cellpadding="0" style="border-width:0;">
<table cellspacing="0" cellpadding="0" style="border-width:0;">
</div>
