我正在努力进行这种排序,需要一些帮助.
我将按排名对子节点进行排序并保存.
例如为了命令主元素内的子节点,我将传递特定部分的ID.
此示例仅适用于第一个后代,现在我卡住了.
XElement x = XElement.Load(xmlString1);
x.Descendants("opt").First().ReplaceNodes(x.Descendants("opt").First()
.Descendants("sel").OrderBy(o => int.Parse(o.Attribute("rank").Value)));
4x.Save(xmlString2);
我需要那样的.
x.Descendants("sub").Where(b => b.Attribute("id").Value == "DFG")
.ReplaceNodes(x.Descendants("opt").First()
.Descendants("sel").OrderBy(o => int.Parse(o.Attribute("rank").Value))
原版的
<main id="AFB" rank="1" name="ROOT">
<sub id="DFG" rank="2" name="SUB1">
<att >
<sel id="JIK" rank="4" name="444" />
<sel id="OKI" rank="2" name="222" />
</att>
<opt>
<sel id="JIK" rank="2" name="122" />
<sel id="OKI" rank="1" name="111" />
</opt>
</sub>
<sub id="EGG" rank="1" name="SUB2" >
<opt>
<sel id="DJI" rank="1" name="111" />
<sel id="LOW" rank="3" name="333" />
<sel id="QWE" rank="2" name="222" />
</opt>

最佳答案 我觉得你有错字.但是,看看这个解决方案:
var text = @"
<main id='AFB' rank='1' name='ROOT'>
<sub id='DFG' rank='2' name='SUB1'>
<opt>
<sel id='JIK' rank='4' name='444' />
<sel id='OKI' rank='2' name='222' />
</opt>
<opt>
<sel id='JIK' rank='2' name='122' />
<sel id='OKI' rank='1' name='111' />
</opt>
</sub>
<sub id='EGG' rank='1' name='SUB2' >
<opt>
<sel id='DJI' rank='1' name='111' />
<sel id='LOW' rank='3' name='333' />
<sel id='QWE' rank='2' name='222' />
</opt>
</sub>
</main>";
var x = XDocument.Parse(text);
x.Root.ReplaceNodes(x.Descendants("sub").OrderBy(a => int.Parse(a.Attribute("rank").Value)));
foreach (var opt in x.Descendants("opt"))
opt.ReplaceNodes(opt.Descendants("sel").OrderBy(a => int.Parse(a.Attribute("rank").Value)));
此时x包含以下XML:
<main id="AFB" rank="1" name="ROOT">
<sub id="EGG" rank="1" name="SUB2">
<opt>
<sel id="DJI" rank="1" name="111" />
<sel id="QWE" rank="2" name="222" />
<sel id="LOW" rank="3" name="333" />
</opt>
</sub>
<sub id="DFG" rank="2" name="SUB1">
<opt>
<sel id="OKI" rank="2" name="222" />
<sel id="JIK" rank="4" name="444" />
</opt>
<opt>
<sel id="OKI" rank="1" name="111" />
<sel id="JIK" rank="2" name="122" />
</opt>
</sub>
</main>
如果att而不是’opt`并且应该包括在内,则以下方法将起作用:
var x = XDocument.Parse(text);
x.Root.ReplaceNodes(x.Descendants("sub").OrderBy(a => int.Parse(a.Attribute("rank").Value)));
foreach (var opt in x.Descendants("sub").Elements())
opt.ReplaceNodes(opt.Descendants("sel").OrderBy(a => int.Parse(a.Attribute("rank").Value)));
如果需要按名称对单个元素进行排序,请使用以下内容(如果不存在任何排名属性或为空,则将其放在后面):
//sub with id=EGG
var sub2 = x.Descendants("sub").FirstOrDefault(a => a.Attribute("id").Value == "EGG");
if (sub2 != null)
{
foreach (var node in sub2.Elements())
node.ReplaceNodes(node.Elements().OrderBy(a =>
{
int rank;
if (a.Attribute("rank") == null || !int.TryParse(a.Attribute("rank").Value, out rank))
rank = int.MaxValue;
return rank;
}));
}
