如何使用 LINQ to XML 将 XML 元素移动到前一个元素之上?
我有以下 XML 结构:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root xmlns:xsi="My Program">
<NotRoot Text="Hello">
<SomeOption Text="Option 1" Centered="False">
<SomeOption Text="Option 1.1" Centered="False">
<SomeOption Text="Option 1.1.1" Centered="false">
<SomeOption Text="A" Centered="false">
<SpecialName Text="Blah blah" Centered="false">
<Number>1</Number>
</SpecialName>
</SomeOption>
<SomeOption Text="B" Centered="false">
<SpecialName Text="Hi" Centered="true">
<SomeStrangeName>42</SomeStrangeName>
</SpecialName>
</SomeOption>
<SomeOption Text="C" Centered="false">
<SpecialName Text="Some text here" Centered="false">
<Stuff>
<Thing1>10</Thing1>
<Thing2>20</Thing2>
<Thing3>30</Thing3>
</Stuff>
</SpecialName>
</SomeOption>
<SomeOption Text="D" Centered="false">
<SpecialName Text="Bye" Centered="false">
<Things>
<Random1>9846516981</Random1>
<Random2>8784749874</Random2>
</Things>
</SpecialName>
</SomeOption>
</SomeOption>
</SomeOption>
</SomeOption>
</NotRoot>
</Root>
我想将元素“C”向上移动一个位置,以便输出如下所示:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root xmlns:xsi="My Program">
<NotRoot Text="Hello">
<SomeOption Text="Option 1" Centered="False">
<SomeOption Text="Option 1.1" Centered="False">
<SomeOption Text="Option 1.1.1" Centered="false">
<SomeOption Text="A" Centered="false">
<SpecialName Text="Blah blah" Centered="false">
<Number>1</Number>
</SpecialName>
</SomeOption>
<SomeOption Text="C" Centered="false">
<SpecialName Text="Some text here" Centered="false">
<Stuff>
<Thing1>10</Thing1>
<Thing2>20</Thing2>
<Thing3>30</Thing3>
</Stuff>
</SpecialName>
</SomeOption>
<SomeOption Text="B" Centered="false">
<SpecialName Text="Hi" Centered="true">
<SomeStrangeName>42</SomeStrangeName>
</SpecialName>
</SomeOption>
<SomeOption Text="D" Centered="false">
<SpecialName Text="Bye" Centered="false">
<Things>
<Random1>9846516981</Random1>
<Random2>8784749874</Random2>
</Things>
</SpecialName>
</SomeOption>
</SomeOption>
</SomeOption>
</SomeOption>
</NotRoot>
</Root>
我的“向上移动元素”按钮可以使用以下代码识别要移动的元素及其上方的元素:
public void MoveElementUp(XElement xeElementToMove)
{
XElement xeElementToMoveInXML = xmlRoot.Descendants().Single(xe => xe == xeElementToMove);
XElement xePrevious = XElement.Parse(xeElementToMoveInXML.PreviousNode.ToString());
// Do something here to put xeElementToMoveInXML before xePrevious
SaveXML();
}
不过,我认为我可能会以错误的方式进行操作。也许我需要将其全部解析为常规文本,然后以某种方式移动它,然后将其转换回 XML 元素?
I have the following XML structure:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root xmlns:xsi="My Program">
<NotRoot Text="Hello">
<SomeOption Text="Option 1" Centered="False">
<SomeOption Text="Option 1.1" Centered="False">
<SomeOption Text="Option 1.1.1" Centered="false">
<SomeOption Text="A" Centered="false">
<SpecialName Text="Blah blah" Centered="false">
<Number>1</Number>
</SpecialName>
</SomeOption>
<SomeOption Text="B" Centered="false">
<SpecialName Text="Hi" Centered="true">
<SomeStrangeName>42</SomeStrangeName>
</SpecialName>
</SomeOption>
<SomeOption Text="C" Centered="false">
<SpecialName Text="Some text here" Centered="false">
<Stuff>
<Thing1>10</Thing1>
<Thing2>20</Thing2>
<Thing3>30</Thing3>
</Stuff>
</SpecialName>
</SomeOption>
<SomeOption Text="D" Centered="false">
<SpecialName Text="Bye" Centered="false">
<Things>
<Random1>9846516981</Random1>
<Random2>8784749874</Random2>
</Things>
</SpecialName>
</SomeOption>
</SomeOption>
</SomeOption>
</SomeOption>
</NotRoot>
</Root>
I would like to move the element "C" up one position so that the output looks like this:
<?xml version="1.0" encoding="utf-8" standalone="yes"?>
<Root xmlns:xsi="My Program">
<NotRoot Text="Hello">
<SomeOption Text="Option 1" Centered="False">
<SomeOption Text="Option 1.1" Centered="False">
<SomeOption Text="Option 1.1.1" Centered="false">
<SomeOption Text="A" Centered="false">
<SpecialName Text="Blah blah" Centered="false">
<Number>1</Number>
</SpecialName>
</SomeOption>
<SomeOption Text="C" Centered="false">
<SpecialName Text="Some text here" Centered="false">
<Stuff>
<Thing1>10</Thing1>
<Thing2>20</Thing2>
<Thing3>30</Thing3>
</Stuff>
</SpecialName>
</SomeOption>
<SomeOption Text="B" Centered="false">
<SpecialName Text="Hi" Centered="true">
<SomeStrangeName>42</SomeStrangeName>
</SpecialName>
</SomeOption>
<SomeOption Text="D" Centered="false">
<SpecialName Text="Bye" Centered="false">
<Things>
<Random1>9846516981</Random1>
<Random2>8784749874</Random2>
</Things>
</SpecialName>
</SomeOption>
</SomeOption>
</SomeOption>
</SomeOption>
</NotRoot>
</Root>
My "Move Element Up" button can recognize the element to move and the element above it with this code:
public void MoveElementUp(XElement xeElementToMove)
{
XElement xeElementToMoveInXML = xmlRoot.Descendants().Single(xe => xe == xeElementToMove);
XElement xePrevious = XElement.Parse(xeElementToMoveInXML.PreviousNode.ToString());
// Do something here to put xeElementToMoveInXML before xePrevious
SaveXML();
}
I think I may be going about it the wrong way though. Perhaps I need to parse it all as regular text, then move it somehow, then convert it back to XML elements?
