Goodreads Api：书评解析：XML中的Iframe：如何删除该Iframe？

我想从goodreads api收到的XML响应中删除review部分内容并显示它。 它似乎是一个Iframe。 你知道怎么做吗

<reviews_widget>

虽然这只是一个简单的解决方案，我还是能够得到答案；可能中断： 但会暂时起作用

            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;
            }

Goodreads API返回简单的XML，所以我不明白为什么它会发送iframe。您是否使用开发人员API或某种插件来检索XML？你能在发生这种情况的地方发布一个链接吗？API链接：它以包含Iframe的XML格式返回一个嵌入式小部件。
