仅使用xpath和.NET C＃获取元素内容 [英] Get element content using only xpath and .NET C#

问题描述

我找到了很多关于如何通过使用简单的xpath expresion和C＃来获取节点内容的文章，例如：

a）xpath

/ bookstore /作者/名字

b）C＃

字符串xpathExpression = / bookstore / author / first-name

nodes = navigator.Select（xpathExpression ）



我想知道如何获取元素内部的内容，并且相同的元素在另一个元素内，另一个元素和另一个元素内。请看下面的代码：



< Cell

< CellContent

< Para

< ; ParaLine

< String`ABCabcABC abcABC abc ABCABCABC。''>

>

>

>

>





我只想从String元素中提取内容ABCabcABC abcABC abc ABCABCABC。

你知道吗？通过使用Xpath表达式和.NET C＃来解决问题？

I''ve found a lot of articles about how to get node content by using simple xpath expresion and C#, for example:
a) xpath
/bookstore/author/first-name
b) C#
string xpathExpression = /bookstore/author/first-name"
nodes = navigator.Select(xpathExpression)

I wonder how to get content that is inside of element, and the same element is inside another element and another and another. Just take a look on code below:

<Cell
<CellContent
<Para
<ParaLine
<String `ABCabcABC abcABC abc ABCABCABC. ''>
>
>
>
>


I only want to extract content ABCabcABC abcABC abc ABCABCABC from String element.
Do you know how to resolve problem by use Xpath expression and .NET C#?

推荐答案

如果您的xml如下所示，那么您可以使用Linq查询它

If your xml is like below then you can query it using Linq

var xml = @"<cell>
                     <cellcontent>
                     <para>
                     <paraline>
                     <string>ABCabcABC abcABC abc ABCABCABC</string></paraline></para></cellcontent></cell>";

            var list = XDocument.Parse(xml).Descendants("ParaLine")
                 .Select(x => x.Element("string").Value).ToList();

list对象将包含string元素的所有值，该元素位于 ParaLine 元素内。

问题是文件看起来不像一个简单的XML。

我的意思是

< NameElement1>

< NameElement2>

abababababababa。

< / NameElement1>

< / NameElement2>



一个元素包括另一个元素，这里：

< NameElement1< NameElement2< NameElement3 abababababababa>>>



如此简单的XPath语法不起作用/ Cell / CellContent / Para / ParaLine / String / text（）;。

我问其他解决方案然后简单的xpath expresion。有什么想法？

Problem is that file doesnt look like a simple xml.
I mean
<NameElement1>
<NameElement2>
abababababababa.
</NameElement1>
</NameElement2>

One element include another element, here:
<NameElement1<NameElement2 <NameElement3 abababababababa >>>

So simple XPath syntax doesn''t work "/Cell/CellContent/Para/ParaLine/String/text()";.
I ask about sth other solution then simple xpath expresion. Any ideas?
