正则匹配问题

Question

<EndTest 
Title="CommandLineTest" 
TUID="" 
Result="Fail" 
Repro="" CA="909962792" LA="910146700" >
  <rti id="3805221601" />
  <ctx id="3065565191" />
</EndTest>数据格式都是这样的 我想得到的是
<EndTest 
Title="CommandLineTest" 
TUID="" 
Result="Fail" 
Repro="" CA="909962792" LA="910146700" >
</EndTest>
怎么匹配  
  <rti id="3805221601" />
  <ctx id="3065565191" />
中的ID是不一样的<EndTest 
Title="CommandLineTest" 
TUID="" 
Result="Fail" 
Repro="" CA="909962792" LA="910146700" >
</EndTest>
中的属性也是不一样的

                    int newCount;
                    int i;
                    newCount = LBoxURL.Items.Count;
                    for (i = 0; i < newCount; i++)
                    {
                        XPathDocument xpDoc = new XPathDocument(LBoxURL.Items[i].ToString());
                        XPathNavigator xpNav = ((IXPathNavigable)xpDoc).CreateNavigator();
                        string xmlPath = "/" + textBox2.Text + "[@" + textBox3.Text + "]";//设定获取对应接点的路径，修改如有修改在这就可以
                        XPathNodeIterator xpIter = xpNav.Select(xmlPath);
                        while (xpIter.MoveNext())
                        {
                            XPathNodeIterator newIter = xpIter.Current.SelectDescendants(XPathNodeType.All, true);
                            int a = newIter.Count;
                            if (a == 3)
                            {
                                ++a;
                                while (newIter.MoveNext())
                                {
                                    if (a != 2 && a != 3)
                                    {
                                        //string con = newIter.Current.InnerXml.ToString();
                                        string content = newIter.Current.OuterXml;
 /********************************************************************************************
                                        content 就是获取的字符串我怎么把那段正则放进去?
*********************************************************************************************/
                                        textBox1.AppendText(content + "\r\n");
                                    }
                                    --a;
                                }
                            }
                        }
                        /*保存到txt文件*/
                        StreamWriter SWriter = new StreamWriter(txtAddress.Text + "\\" + this.txtTitle.Text);//写入地址
                        SWriter.Write(textBox1.Text);//内容
                        SWriter.Close();
                    }
                    /*end*/
                    MessageBox.Show("保存成功！");
                }
                catch (Exception ex)
                {
                    MessageBox.Show("出错" + ex.ToString());
                }

百度一下Regex.Replace，结合我给的表达式，把组1替换为空就可以了。
