如何用python自动填写网页中每一种商品的数量
selenium模块懂一点，但是不懂得定位到每一个商品的VALUE值
网页代码如下，求高手相助。

<li title="商品一" id="11101116" brandimage="11101116_3.jpg">

  <span class="table-cell num">

    <span class="numText">1</span>

  </span>

  <span class="table-cell brandId z-hide"> 11101116</span>

  <span class="table-cell brandName">

    <a class="brandDetailLink" href="" "="" target="_blank">

	  <span class="brandNameText">商品一</span> 

	</a>

  </span>

  <span class="table-cell tradePrice c-font-red"> 57.24</span>

  <span class="table-cell retailPrice">  70.00</span>

  <span class="table-cell inputContainer ">

    <a class="suba"> - </a>

	<input class="qtyDemandInput" name="qtyDemandInput" value="1" onkeyup="this.value=this.value.replace(/\D/g,'')" onafterpaste="this.value=this.value.replace(/\D/g,'')" type="text">

	<a class="adda"> + </a>

  </span>

  <span class="table-cell qtyOrder c-font-red">0</span>

  <span class="table-cell qtyUpperLimit">0</span>

  <span class="table-cell amtOrder">0.00</span>

  <span class="table-cell">

    <a class="link collect-btn" style="margin-right: 10px">收藏</a>

	<a class="link del-btn">删除</a>

  </span>

</li>

<li title="商品2" id="11101116" brandimage="11101116_3.jpg">

  <span class="table-cell num">

    <span class="numText">1</span>

  </span>

  <span class="table-cell brandId z-hide"> 11101116</span>

  <span class="table-cell brandName">

    <a class="brandDetailLink" href="" "="" target="_blank">

	  <span class="brandNameText">商品2</span> 

	</a>

  </span>

  <span class="table-cell tradePrice c-font-red"> 57.24</span>

  <span class="table-cell retailPrice">  70.00</span>

  <span class="table-cell inputContainer ">

    <a class="suba"> - </a>

	<input class="qtyDemandInput" name="qtyDemandInput" value="1" onkeyup="this.value=this.value.replace(/\D/g,'')" onafterpaste="this.value=this.value.replace(/\D/g,'')" type="text">

	<a class="adda"> + </a>

  </span>

  <span class="table-cell qtyOrder c-font-red">0</span>

  <span class="table-cell qtyUpperLimit">0</span>

  <span class="table-cell amtOrder">0.00</span>

  <span class="table-cell">

    <a class="link collect-btn" style="margin-right: 10px">收藏</a>

	<a class="link del-btn">删除</a>

  </span>

</li>
