[英]How to Get a specific Value of an XML Node from XDocument
I am asking essentially the same question as found in this post: How to Get XML Node from XDocument with the exception of attempting to do a one-shot return of the CData value in a single line of code. 我问的是与本文中发现的问题基本相同的问题: 如何从XDocument获取XML节点,但尝试在单行代码中一次性返回CData值。 I'm attempting to get the return in the below function to work properly:
我试图在下面的函数中获得返回值以正常工作:
private string RetrieveFormattedString(string controlId)
{
return template.Descendants("Template")
.Where(templateNode => templateNode.Value == controlId)
.Where(tmp => tmp.Name == "Format").Select(y => y.Value).ToString();
}
I have the following XML below: 我在下面有以下XML:
<?xml version="1.0" encoding="utf-8" ?>
<Templates>
<Template>
<Name>NodeName1</Name>
<Parameter Type="TextBox" Name="conferenceID">{__otcConferenceID__}</Parameter>
<Parameter Type="TextBox" Name="conferenceCode">{__otcConferenceCode__}</Parameter>
<Format>
<![CDATA[ <b>NodeName1</b><br /> <table><tr><td>iPhone</td><td>{__otcConferenceID__},#,{__otcConferenceCode__}</td></tr></table>]]>
</Format>
</Template>
<Template>
<Name>NodeName2</Name>
<Parameter Type="TextBox" Name="conferenceID">{__otcConferenceID__}</Parameter>
<Parameter Type="TextBox" Name="conferenceCode">{__otcConferenceCode__}</Parameter>
<Format>
<![CDATA[ <b>NodeName2</b><br /> <table><tr><td>iPhone</td><td>{__otcConferenceID__},#,{__otcConferenceCode__}</td></tr></table>]]>
</Format>
</Template>
</Templates>
I know I'm doing this incorrectly, and was hoping to get a larger set of eyes on it. 我知道我做错了,并希望对此有更大的关注。
private string RetrieveFormattedString(XDocument xDoc, string nodeName)
{
return xDoc.Descendants("Template")
.First(t => t.Element("Name").Value == nodeName)
.Element("Format").Value;
}
