將XML元素移動到特定位置

好日子，我需要將所有ComposedBlock標記移動到TextBlock的最後一個位置，示例XML位於下方。將XML元素移動到特定位置

這是XML輸入：

<parent> 
<ComposedBlock ID="P1_CB0000001" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727"> 
    <GraphicalElement ID="P1_CB0000001_SUB" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727" /> 
</ComposedBlock> 
<ComposedBlock ID="P1_CB0000002" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730"> 
    <GraphicalElement ID="P1_CB0000002_SUB" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730" /> 
</ComposedBlock> 
<TextBlock ID="P1_TB0000006" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
    <TextLine ID="P1_TL0000028" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120"> 
     <String ID="P1_ST0000165" HPOS="2539" VPOS="1680" WIDTH="63" HEIGHT="86" CONTENT="ijt" /> 
     <SP ID="P1_SP0000156" HPOS="2602" VPOS="1766" /> 
    </TextLine> 
</TextBlock> 
<TextBlock ID="P1_TB0000011" HPOS="4406" VPOS="5170" WIDTH="1724" HEIGHT="1003" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
    <TextLine ID="P1_TL0000083" HPOS="4411" VPOS="5170" WIDTH="1714" HEIGHT="120"> 
     <String ID="P1_ST0000532" HPOS="4411" VPOS="5170" WIDTH="346" HEIGHT="91" CONTENT="Change" /> 
     <SP ID="P1_SP0000513" HPOS="4757" VPOS="5261" /> 
     <String ID="P1_ST0000533" HPOS="4776" VPOS="5198" WIDTH="230" HEIGHT="63" CONTENT="yo0ur" /> 
     <SP ID="P1_SP0000514" HPOS="5006" VPOS="5261" /> 
    </TextLine> 
</TextBlock> 
</parent>

，這是所需的輸出：

<parent> 
<TextBlock ID="P1_TB0000006" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
    <TextLine ID="P1_TL0000028" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120"> 
     <String ID="P1_ST0000165" HPOS="2539" VPOS="1680" WIDTH="63" HEIGHT="86" CONTENT="ijt" /> 
     <SP ID="P1_SP0000156" HPOS="2602" VPOS="1766" /> 
    </TextLine> 
</TextBlock> 
<TextBlock ID="P1_TB0000011" HPOS="4406" VPOS="5170" WIDTH="1724" HEIGHT="1003" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
    <TextLine ID="P1_TL0000083" HPOS="4411" VPOS="5170" WIDTH="1714" HEIGHT="120"> 
     <String ID="P1_ST0000532" HPOS="4411" VPOS="5170" WIDTH="346" HEIGHT="91" CONTENT="Change" /> 
     <SP ID="P1_SP0000513" HPOS="4757" VPOS="5261" /> 
     <String ID="P1_ST0000533" HPOS="4776" VPOS="5198" WIDTH="230" HEIGHT="63" CONTENT="yo0ur" /> 
     <SP ID="P1_SP0000514" HPOS="5006" VPOS="5261" /> 
    </TextLine> 
</TextBlock> 
<ComposedBlock ID="P1_CB0000001" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727"> 
    <GraphicalElement ID="P1_CB0000001_SUB" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727" /> 
</ComposedBlock> 
<ComposedBlock ID="P1_CB0000002" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730"> 
    <GraphicalElement ID="P1_CB0000002_SUB" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730" /> 
</ComposedBlock> 
</parent>

這裏是我的代碼：

XElement doc = XElement.Parse(reader); 
IEnumerable<XElement> wd = 
    from el in doc.Descendants("ComposedBlock").ToList() 
    select el; 

foreach (XElement el in wd) 
{ 
    //what do i need to do here? 
}

查找當前「前一個「元素
從樹上取下
您發現

像這樣的元素之前將其插入：

static void MoveElementUp(XElement element) 
{ 
    // Walk backwards until we find an element - ignore text nodes 
    XNode previousNode = element.PreviousNode; 
    while (previousNode != null && !(previousNode is XElement)) 
    { 
     previousNode = previousNode.PreviousNode; 
    } 
    if (previousNode == null) 
    { 
     throw new ArgumentException("Nowhere to move element to!"); 
    } 
    element.Remove(); 
    previousNode.AddBeforeSelf(element); 
}

這裏是我的解決方案

它不是一個很好的代碼，但它作品

我創建了一個使用XElement作爲數據類型的列表。其中，i添加元素我需要轉移

XDocument doc = XDocument.Parse(alto); 
       var a = doc.Descendants("TextBlock").Last(); 
       foreach (var item in lstpc) 
       { 
        a.AddAfterSelf(new XElement(item)); 
       }

的另一種方法與XML LINQ

  XElement doc = XElement.Load(FILENAME); 
      XElement parent = doc.DescendantsAndSelf("parent").FirstOrDefault(); 
      List<XElement> wd = parent.Elements("ComposedBlock").ToList(); 

      foreach (XElement composedBlock in wd) 
      { 
       composedBlock.ReplaceWith(null); 
      } 
      parent.Add(wd);

爲什麼不調用Remove而不是ReplaceW ith（null）？ – CSharpie

我沒有想到它。 – jdweng

在VB中它是這樣

For Each el As XElement In xe...<ComposedBlock>.ToList 
     xe.Elements.LastOrDefault.AddAfterSelf(el) 
     el.Remove() 
    Next

使用該加載和/或測試

Dim xe As XElement 
    ' to load from a file 
    'xe = XElement.Load(yourpath) 
    ' for testing 
    xe = <parent> 
      <ComposedBlock ID="P1_CB0000001" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727"> 
       <GraphicalElement ID="P1_CB0000001_SUB" HPOS="6278" VPOS="1670" WIDTH="3610" HEIGHT="2727"/> 
      </ComposedBlock> 
      <ComposedBlock ID="P1_CB0000002" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730"> 
       <GraphicalElement ID="P1_CB0000002_SUB" HPOS="653" VPOS="1728" WIDTH="1689" HEIGHT="730"/> 
      </ComposedBlock> 
      <TextBlock ID="P1_TB0000006" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
       <TextLine ID="P1_TL0000028" HPOS="2539" VPOS="1675" WIDTH="1200" HEIGHT="120"> 
        <String ID="P1_ST0000165" HPOS="2539" VPOS="1680" WIDTH="63" HEIGHT="86" CONTENT="ijt"/> 
        <SP ID="P1_SP0000156" HPOS="2602" VPOS="1766"/> 
       </TextLine> 
      </TextBlock> 
      <TextBlock ID="P1_TB0000011" HPOS="4406" VPOS="5170" WIDTH="1724" HEIGHT="1003" LANG="en" STYLEREFS="PAR_JUSTIFIED"> 
       <TextLine ID="P1_TL0000083" HPOS="4411" VPOS="5170" WIDTH="1714" HEIGHT="120">

        <SP ID="P1_SP0000514" HPOS="5006" VPOS="5261"/> 
       </TextLine>
