查找xml文件的特定标记的行号

Question

如何查找xml文件的特定标签的标签和行号， 例如：

<sec id="fm.s2">
<title>Acknowledgments</title>
</sec>
<p>Center for Evidence and Practice Improvement</p>
<p>Agency for Healthcare Research and Quality</p>
<sec id="fm.s2">
<title>Director</title>
</sec>
<p>Center for Evidence and Practice Improvement</p>
<p>Agency for Healthcare Research and Quality</p>
<sec id="fm.s2">
<title>Acknowledgments</title>
</sec>

在这个例子中，我想获得<title>包含“Acknowledgements”文本的行号。

你可以用linq

来做

var xml = XDocument.Load(@"path", LoadOptions.SetLineInfo);

var lineNumbers = xml.Descendants()
            .Where(x =>!x.Descendants().Any() && //exact node contains the value
                        x.Value.Contains("Acknowledgments"))
            .Cast<IXmlLineInfo>()
            .Select(x => x.LineNumber);
