c＃使用XDocument再次解析xml

Question

我已经查看过很多帮助文件和很多类似的问题，但是我无法比返回后代集合更进一步。

我想要实现的是获取一个数组，其中包含id或tag个孩子的ph元素的所有bpt属性的值（不是那些在st

的XPath中有xliff\file\header\tag-defs）的人

这是xml。我删除了其他标签，为了简单起见，它在标题元素之后被截断：

代码方面我尝试了不同的版本，但这就是我所处的位置：

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...

}

感谢您提前提供任何帮助。

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;
}
