XPath-选择所选子节点的文本 [英] XPath - select text of selected child nodes

问题描述

鉴于我有以下xml:

Given that I have a following xml:

<div id="Main">
    <div class="quote">
        This is a quote and I don't want this text
    </div> 
    <p>
        This is content.
    </p>
    <p>  
        This is also content and I want both of them
    </p>
</div>

是否存在"XPath" ，以帮助我选择 div#Main 的内部文本作为单个节点，但必须排除任何 div.quote .

Is there "a XPath" to help me select inner text of div#Main as a single node, but must exclude texts of any div.quote.

我只想输入以下文字:这很满足.这也很满足，而且我俩都想要"

I just want the text: "This is content.This is also content and I want both of them"

预先感谢

这是测试XPath的代码，我将HtmlAgilityPack与.NET结合使用，但我相信xPath应该可以与任何语言一起使用

Here is the code to test the XPath, I'm using .NET with HtmlAgilityPack but I believe the xPath should work with any languages

[Test]
public void TestSelectNode()
{
    // Arrange 
    var html = "<div id=\"Main\"><div class=\"quote\">This is a quote and I don't want this text</div><p>This is content.</p><p>This is also content and I want both of them</p></div>";
    var xPath = "//div/*[not(self::div and @class=\"quote\")]/text()";

    var doc = new HtmlDocument();
    doc.LoadHtml(html);

    // Action
    var node = doc.DocumentNode.SelectSingleNode(xPath);

    // Assert
    Assert.AreEqual("This is content.This is also content and I want both of them", node.InnerText);
}

由于xPath仍然不正确，测试显然失败了.

The test was failed obviously because the xPath is still not correct.

Test 'XPathExperiments/TestSelectNode' failed:
    Expected values to be equal.

    Expected Value : "This is content.This is also content and I want both of them"
    Actual Value   : "This is content."

推荐答案

我不认为有一个XPath可以将其作为单个节点提供，因为您正在尝试获取 aren'的值一个节点.您有理由不能这样做吗?

I don't think there is an XPath that will give you this as a single node, because the values you're trying to obtain aren't a single node. Is there a reason you can't do this?

StringBuilder sb = new StringBuilder();
// Action
var nodes = doc.DocumentNode.SelectNodes(xPath);
foreach(var node in nodes)
{
   sb.Append(node.InnerText);
}

// Assert
Assert.AreEqual("This is content.This is also content and I want both of them", 
                sb.ToString());
