XML不读取特定节点

标签： c# xml winforms datagridview xmlreader

我需要读出案例编号并将其放入datagridview行。正在选择其他元素，但我无法获取文件路径中每个XML的案例编号（nc：CaseTrackingID）。我遇到的另一个问题是为每个存在的Base64Object抓取nc：DocumentDescriptionText（这个数字的范围可以从一次到正在处理的文件数量不等）。我已经包含了XML示例和用于读取XML的当前代码。任何帮助将不胜感激。

XML：

<?xml version="1.0"?>
    <nc:DocumentDescriptionText s:id="ReviewWorkQueueId">XXX</nc:DocumentDescriptionText>
    <nc:DocumentDescriptionText s:id="ReviewWorkQueue">XXXXXXXXXXXXXXX</nc:DocumentDescriptionText>

看起来CaseTrackingID标签周围有**。你试过从XML文件中删除double *吗？我不确定**的意义是什么，但可能它干扰了阅读文件。

**<nc:CaseTrackingID>XXXXXXXXXX</nc:CaseTrackingID>**

这看起来像个问题。不确定**是否需要存在。

修改

如何改变这样的代码呢。这将在遍历节点时捕获文本节点

if (xr.NodeType == XmlNodeType.Element)
{
    element = xr.Name;
}
else if (xr.NodeType == XmlNodeType.Text)
{
    if (element == "nc:PersonFullName")
    {
        attyName = xr.Value;
    }
    else if (element == "nc:IdentificationID")
    {
        elementCount++;
        DocID = xr.Value;
        if (elementCount == 1)
        {
            reqID = DocID;
        }

        if (elementCount == 3)
        {
            empName = DocID;
        }

        if (elementCount == 8)
        {
            attyBarID = DocID;

            elementCount = 0;
            break;
        }
    }
    else if (element == "nc:CaseTrackingID")
    {
        elementCount++;
        DocID = xr.Value;
        if (elementCount == 1)
        {
            reqID = DocID;
        }

        if (elementCount == 3)
        {
            empName = DocID;
        }

        if (elementCount == 8)
        {
            attyBarID = DocID;

            elementCount = 0;
            break;
        }
    }
}

还将elelment变量放在循环外

答案 1 :(得分：0)

因此，根据我的研究，我使它变得比需要的更复杂。能够直接获取元素比通过“IF”语句运行更有益。我注意到elementCount ++不允许读取下面的元素。

xr.ReadToFollowing("nc:CaseTrackingID");//this will directly get the element name
casenumber = xr.ReadElementContentAsString();
