使用Jsoup读取跨度数据

Question

int traverse_and_calculate(const vector< vector<int> > &board, int start_row, int start_column, int inc_row, int inc_col, int length)
{
  for (int row = start_row, column = start_column, step = 0; step < length; row += inc_row, col += inc_col)
  {

  }
}

我想使用jsoup读取值Rs.999。 我的代码是

<div style="float:left;width:100%">

                <span class="scratchPrice" style="font-size:12px;font-weight:normal; color :#999999"><del>Rs&nbsp;2999</del>&nbsp;</span>
                <span class="discountPrice" style="font-size:12px;font-weight:normal;color: #f5615f">(66%&nbsp;off)</span>

            <span style="font-size:16px;font-weight:bold;color:#5a5a5a;width:100%;float:left;">Rs&nbsp;999&nbsp;</span>
            </div>

并使用此代码我获得了价值（66％的折扣） 请看一下这段代码。 感谢你..

Answer 1

您将获得以下每个跨度，并检查其最后一个跨度。

Document doc;
Element div;
Elements span;

div = doc.select("div").get(0); // select the first div.
span = div.select("span");

for (int i = 0; i < span.size(); i++) {
    Element span = span.get(i);

//check here is its last span from div than extract this value will return RS.999
    }

Answer 2

使用此CSS查询：

span.scratchPrice > del

DEMO

示例代码

Element del = document.select("span.scratchPrice > del").first();
System.out.println(del.text());
