Question

我想从goodreads api收到的XML响应中删除评论部分内容并显示它。它似乎是一个iframe。所以任何想法如何做到这一点??

<reviews_widget>

我能够得到答案，虽然它只是一个简单的解决方案;可能会打破:( 但是会暂时工作。

            Label lb2 = new Label();
            string st = html;

            int stindex, endindex;
            string subst;
            stindex = st.IndexOf("<iframe");
            endindex = st.IndexOf("</iframe>") + 9;
            int lin = st.LastIndexOf("</iframe>") + 9;
            while ((endindex <= lin) && (stindex > 0))
            {
                subst = st.Substring(stindex, endindex - stindex);
                lb2.Text = subst;
                PlaceHolder1.Controls.Add(lb2);
                st = st.Substring(endindex);
                stindex = st.IndexOf("<iframe");
                endindex = st.IndexOf("</iframe>") + 9;
            }
