从 XmlDocument 中删除节点 [英] Removing nodes from an XmlDocument

问题描述

下面的代码应该找到合适的项目标签并将其从 XmlDocument 中删除，但是当我测试它时，它说:

The following code should find the appropriate project tag and remove it from the XmlDocument, however when I test it, it says:

要移除的节点不是该节点的子节点.

有人知道这样做的正确方法吗?

Does anyone know the proper way to do this?

public void DeleteProject (string projectName)
{
    string ccConfigPath = ConfigurationManager.AppSettings["ConfigPath"];

    XmlDocument configDoc = new XmlDocument();

    configDoc.Load(ccConfigPath);

    XmlNodeList projectNodes = configDoc.GetElementsByTagName("project");

    for (int i = 0; i < projectNodes.Count; i++)
    {
        if (projectNodes[i].Attributes["name"] != null)
        {
            if (projectName == projectNodes[i].Attributes["name"].InnerText)
            {                                                
                configDoc.RemoveChild(projectNodes[i]);
                configDoc.Save(ccConfigPath);
            }
        }
    }
}

更新

已修复.我做了两件事:

Fixed. I did two things:

XmlNode project = configDoc.SelectSingleNode("//project[@name='" + projectName + "']");

用 XPath 查询替换 For 循环，这不是为了修复它，只是因为它是一种更好的方法.

Replaced the For loop with an XPath query, which wasn't for fixing it, just because it was a better approach.

实际修复是:

project.ParentNode.RemoveChild(project);

感谢帕特和查克的建议.

Thanks Pat and Chuck for this suggestion.

推荐答案

代替

configDoc.RemoveChild(projectNodes[i]);

试试

projectNodes[i].parentNode.RemoveChild(projectNodes[i]);
