通过C＃读取和编辑XML文件中的特定XML代码

Question

我正在尝试用C＃创建一个程序，该程序将打开Main.xml文件中提到的所有XML文件，查找某些名称标签，并在其中添加后缀（blabla_name，{ {1}}，Blabla_unit_name，Location_code）。问题在于，名称是关系属性，其名称取决于所使用的文件而具有不同的标记。例如，WO_Name文件中的名称可能是<Structure_name>，但可能是structure.xml在<From_structure_name>文件中。

因此，我要做的是创建一个XML解析程序，该程序将从equipment.xml文件中获取所有链接，打开每个文件，读取并查找我要查找的名称标签，然后保存它们字符串列表中的值（Main.XML）。目的是，在读取并将所有必需的值存储在列表中之后，我想逐个索引遍历每个文件的索引，并将innertext的列表innertext中的值替换到另一个文件中。例如，使用新值+后缀。

我已经完成了将近80％的工作，但我一直在苦苦挣扎的是后缀添加了不止一次。那是因为我想不出一个条件，该条件会将写方法限制为仅在读取过程完成后才能执行，但同时也在每个文件上执行。

这是我的代码：

<structure_name> && <from_structure_name>

这是我正在使用的XML文件的一部分：

{
    if (textBox1.Text == null)
        MessageBox.Show("Please choose a folder");

        string location = textBox3.Text;
        string workOrder = textBox4.Text;

        List<string> contentList = new List<string>();

        if ((postfix.Length > 0) && (postfix.Length <= 2))
        {
