我陷入了一些 LINQ to XML 代码 (

我陷入了一些 LINQ to XML 代码的困境。在 for 循环中调用一个方法，该方法成功返回标记的内容，该标记包含来自具有 4000+ 个 kml 文件的正确 id 的总数。我说成功了，但有一点需要注意。标记包含，.net 将其转换为 .无论如何，我无法弄清楚如何对其进行解析，以便保留所有字符（>）。以下是相关的 C# 代码：

…in main class

public partial class ResultsGeneral : BasePage {
public List<string> rightVenues = new List<string>();
XNamespace spc = "http://www.opengis.net/kml/2.2";
XDocument Placemarks = XDocument.Load(HttpContext.Current.Server.MapPath("~/venuesCompleteGood.kml"));

…in protected void Page_Load(object sender, EventArgs e) {

for (int q = 0; q <= rightVenues.Count; q++) {
    getInfo(rightVenues[q]); //get info contains a list of placemark ids
};

…

public void getInfo(string ids) {
    var aPlacemark =
    from plMark in Placemarks.Descendants(spc + "Placemark")
        where plMark.Attribute("id").Value.Equals(ids.ToString())
        select plMark;
    foreach (XElement plMark in aPlacemark) {
        quKML.Text = quKML.Text + "<br>" + 
               plMark.ToString(SaveOptions.DisableFormatting);
    }
}

…kml 的片段：

<?xml version="1.0" encoding="UTF-8"?>
    <kml xmlns="http://www.opengis.net/kml/2.2">
        <Document>
            <Placemark id="33">
               <name>
                    Madison Square Garden
               </name>
               <description>

                    </coordinates>
               </Point>
          </Placemark>

…返回的部分内容：

<placemark id="33" xmlns="http://www.opengis.net/kml/2.2"><name>
                    Madison Square Garden

I’m stuck on some LINQ to XML code. A method is called in a for loop that successfully returns the contents of a <placemark> tag containing the correct <placemark> id from a kml file that has 4000+ <placemark>’s total. I say successfully with one caveat. The <description> tag contains <![CDATA[ ]]> that .net translates into <![CDATA[ ]] > . I can’t figure out anyway of getting this parsed so that it preserves all of the characters (the >). Here is the relevant c# code:

…in main class

public partial class ResultsGeneral : BasePage {
public List<string> rightVenues = new List<string>();
XNamespace spc = "http://www.opengis.net/kml/2.2";
XDocument Placemarks = XDocument.Load(HttpContext.Current.Server.MapPath("~/venuesCompleteGood.kml"));

…in protected void Page_Load(object sender, EventArgs e) {

for (int q = 0; q <= rightVenues.Count; q++) {
    getInfo(rightVenues[q]); //get info contains a list of placemark ids
};

…

public void getInfo(string ids) {
    var aPlacemark =
    from plMark in Placemarks.Descendants(spc + "Placemark")
        where plMark.Attribute("id").Value.Equals(ids.ToString())
        select plMark;
    foreach (XElement plMark in aPlacemark) {
        quKML.Text = quKML.Text + "<br>" + 
               plMark.ToString(SaveOptions.DisableFormatting);
    }
}

…a snippet of the kml:

<?xml version="1.0" encoding="UTF-8"?>
    <kml xmlns="http://www.opengis.net/kml/2.2">
        <Document>
            <Placemark id="33">
               <name>
                    Madison Square Garden
               </name>
               <description>
                    <![CDATA[<br>
4 Penn Plaza<br>
<br>

United States of America ]]>
               </description>
               <Point>
                    <coordinates>
                         -73.99337100000002,40.750354
                    </coordinates>
               </Point>
          </Placemark>

…part of what is returned:

<placemark id="33" xmlns="http://www.opengis.net/kml/2.2"><name>
                    Madison Square Garden
               </name><description><!--[CDATA[<br-->

                    </coordinates></point></placemark>

note the ]]> after America.
