删除节点从一个XmlDocument [英] Removing nodes from an XmlDocument

问题描述

下面code应该找到合适的项目标签，并从XmlDocument的删除它，但是当我测试了一下，说：

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

要删除的节点不是此节点的子节点。

有谁知道正确的方式来做到这一点？

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

修正。我做了两件事情：

Fixed. I did two things:

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

替换For循环使用XPath查询，这是不固定的，只是因为它是一个更好的办法。

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

实际的修复是：

project.ParentNode.RemoveChild(project);

感谢帕特和Chuck这一建议。

Thanks Pat and Chuck for this suggestion.

推荐答案

configDoc.RemoveChild(projectNodes[i]);

尝试

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