xpath got wrong html attribute - php

Question

So, I have this PHP scraper code and HTML below that I want to scrape using Xpath.
When I try to scrape every #href, it shows outerHTML 14, when it is supposes to be 14
The #href is cut in half where the space are. What causes this?
$content = $xpath->query('//a');
foreach($content as $c){
var_dump(htmlspecialchars($c->C14N())); echo '<br>';
}
The one above is the CURL code.
Here is the HTML.
<div class="outercalendar" id="maincalendar821"><table class="calendarHeader">
<tbody><tr>
<td><input type="button" onclick="AjxGetMainCalendarMonth('2', '2015', '821')" value="<"></td>
<td class="calendarHeader" colspan="5">March 2015</td>
<td><input type="button" onclick="AjxGetMainCalendarMonth('4', '2015', '821')" value=">"></td>
</tr>
</tbody></table>
<table class="calendar">
<tbody><tr>
<td class="calendarDay">S</td>
<td class="calendarDay">M</td>
<td class="calendarDay">T</td>
<td class="calendarDay">W</td>
<td class="calendarDay">T</td>
<td class="calendarDay">F</td>
<td class="calendarDay">S</td>
</tr>
<tr>
<td class="calendar">1</td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar">7</td>
</tr>
<tr>
<td class="calendar">8</td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar">14</td>
</tr>
<tr>
<td class="calendar">15</td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar">21</td>
</tr>
<tr>
<td class="calendar">22</td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar">28</td>
</tr>
<tr>
<td class="calendar">29</td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
<td class="calendar"> </td>
</tr>
</tbody></table>
</div>

Answer 1

The issue could be in the structure of the info stored in the tag.
I would suggest starting with a more detailed xpath:
//a/#href
so your initial code would be:
$content = $xpath->query('//a/#href');
