任何人都可以帮助我让这个xml编辑工作吗？

Question

我正在尝试制作NDS Wiiu VC Injector（它将nds游戏注入wiiu vc），我正在尝试编辑XML长短名称，但它不起作用，它不会将内容写入该文件

这是xml的一部分：

<?xml version="1.0" encoding="utf-8"?>
<menu type="complex" access="777">
    <invisible_flag type="hexBinary" length="4">00000000</invisible_flag>
    <reserved_flag0 type="hexBinary" length="4">00010001</reserved_flag0>
    <reserved_flag1 type="hexBinary" length="4">00000000</reserved_flag1>
    <reserved_flag2 type="hexBinary" length="4">00000000</reserved_flag2>
    <reserved_flag3 type="hexBinary" length="4">00000000</reserved_flag3>
    <reserved_flag4 type="hexBinary" length="4">00000000</reserved_flag4>
    <reserved_flag5 type="hexBinary" length="4">00000000</reserved_flag5>
    <reserved_flag6 type="hexBinary" length="4">00000003</reserved_flag6>
    <reserved_flag7 type="hexBinary" length="4">00000001</reserved_flag7>
    <longname_ja type="string" length="512">
    </longname_ja>
    <longname_en type="string" length="512">WarioWare: Touched!</longname_en>
    <longname_fr type="string" length="512">WarioWare: Touched!</longname_fr>
    <longname_de type="string" length="512">WarioWare: Touched!</longname_de>
    <longname_it type="string" length="512">WarioWare: Touched!</longname_it>
    <longname_es type="string" length="512">WarioWare: Touched!</longname_es>

这是我正在使用的代码：

string xmlFile = Path.Combine(
    Path.GetDirectoryName(
        Assembly.GetExecutingAssembly().Location
    )
    , @"TOOLS\EDIT\meta.xml"
);
XmlDocument doc = new XmlDocument();
doc.Load(xmlFile);

string newValue = textBox5.Text;

XmlNodeList list = doc.SelectNodes("//@*"); // Forgot the slashes here...
IEnumerable<XmlNode> filteredList = list.Cast<XmlNode>().
    Where(item => item.Name.ToLower().Contains("longname")); // Name property instead of Value

 foreach (XmlNode n in filteredList)
 {
     n.Value = newValue; // Setting the value.
 }

 doc.Save(xmlFile);
