我正在编写一个只回显价格的脚本。如果我做：
$alttag = $oNode['p'];
echo $alttag;
它会回显<p></p>. 所以它会回显：
roodmerk of cafeïnevrij pak 500 克
2 巴肯
prijs 每公斤 1,99
199
从网站上，所以你可以看到它与 199 相呼应，这是价格，但首先我只需要 199<p></p>并且我想要。或 , 在 199 之间，因此它将显示 1,99 或 1.99。
如果我做：
$alttag = $oNode['p sup'];
echo $alttag;
<sup></sup>
如果我这样做，它只会回显 99 ：
$alttag = $oNode['p sup'];
$maintag = $oNode['p']->attr('alt');
echo $maintag . $alttag;
嗯......这什么都不做我怎么才能只得到 1 和 99 并放置一个 . 或者，在它之间，它看起来像 1,99 或 1.99？
<div class="item-prijs">
<p>
<cufon class="cufon cufon-canvas" alt="1" style="width: 27px; height: 42px; ">
<canvas width="47" height="43" style="width: 47px; height: 43px; top: -1px; left: -2px; "></canvas>
<cufontext>1</cufontext>
