c# 使用 XDocument 再次解析 xml

Question

我查看了很多帮助文件和很多与我类似的问题，但除了返回后代，我无法进一步了解 collection。

我想要实现的是获得一个数组，其中包含具有 ph 或 bpt tag 元素的所有 id 属性的值=30=]（不是那些 st）在 xliff\file\header\tag-defs

的 XPath 中

这里是xml。为了简单起见，我去掉了其他标签，它在 header 元素之后被截断了：

Code-wise 我尝试了不同的版本，但这是我所在的位置：

private static XDocument xliff;

public static List<XElement> GetTagArray(string FilePath)
{
    xliff = XDocument.Load(Path.GetFullPath(FilePath));
    XNamespace ns = "http://sdl.com/FileTypes/SdlXliff/1.0";
    var elements = xliff.Descendants().Elements(ns + "tag-defs").Elements().Select(e => e.Elements(ns + "ph")).ToList();

//and here I am stuck as not matter what I do above it returns empty...

}

提前感谢您的帮助。

Answer 1

未经测试的代码，但请尝试以下内容：

XNamespace sdl = @"http://sdl.com/FileTypes/SdlXliff/1.0";
XNamespace ns = @"urn:oasis:names:tc:xliff:document:1.2";
foreach (var tag in xliff.Descendants(sdl + "tag"))
{
    foreach (var ph in tag.Elements(sdl + "ph"))
    {
        // Code here to process
    }
}

Answer 2

在 Jesse Good 的帮助下，解决方案是：

private static XDocument xliff;

public static int[] GetTagArray(string FilePath)
{
    xliff = XDocument.Load(Path.GetFullPath(FilePath));
    XNamespace ns = "http://sdl.com/FileTypes/SdlXliff/1.0";
    int[] elements = xliff.Descendants().Elements(ns + "tag-defs").Elements(ns + "tag").Elements(ns + "ph").Select(e => Int32.Parse(e.Parent.Attribute("id").Value)).ToArray();
    int[] elements2 = xliff.Descendants().Elements(ns + "tag-defs").Elements(ns + "tag").Elements(ns + "bpt").Select(e => Int32.Parse(e.Parent.Attribute("id").Value)).ToArray();

    int[] intarray = elements.Concat(elements2).ToArray();
    Array.Sort(intarray);

    return intarray;
}
