通过在xslt1 xml元素重复节点的分组的xsl(xsl grouping of repetiti

我有一个复杂的XML结构，看起来像：

  <Items>
      <Item>
          <ItemTexts>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
              <ItemTextsLine>1</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
              <ItemTextsLine>2</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
              <ItemTextsLine>3</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
              <ItemTextsLine>4</ItemTextsLine>
            </ItemText>
          </ItemTexts>
         </Item>
    <Item>
          <ItemTexts>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
              <ItemTextsLine>1</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
              <ItemTextsLine>2</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
              <ItemTextsLine>3</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
              <ItemTextsLine>4</ItemTextsLine>
            </ItemText>
          </ItemTexts>
         </Item>
<Item>
          <ItemTexts>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description11</ItemTextsTypeDesc>
              <ItemTextsLine>1</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type1</ItemTextsType>
              <ItemTextsTypeDesc>description12</ItemTextsTypeDesc>
              <ItemTextsLine>2</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
              <ItemTextsLine>3</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
              <ItemTextsLine>4</ItemTextsLine>
            </ItemText>
          </ItemTexts>
         </Item>
    <Item>
          <ItemTexts>
            <ItemText>
              <ItemTextsType>type3</ItemTextsType>
              <ItemTextsTypeDesc>description31</ItemTextsTypeDesc>
              <ItemTextsLine>1</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type3</ItemTextsType>
              <ItemTextsTypeDesc>description32</ItemTextsTypeDesc>
              <ItemTextsLine>2</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description21</ItemTextsTypeDesc>
              <ItemTextsLine>3</ItemTextsLine>
            </ItemText>
            <ItemText>
              <ItemTextsType>type2</ItemTextsType>
              <ItemTextsTypeDesc>description22</ItemTextsTypeDesc>
              <ItemTextsLine>4</ItemTextsLine>
            </ItemText>
          </ItemTexts>
         </Item>
    </Items>

我像每个项目运行的xsl：

<xsl:for-each select="Items/Item">

我需要一个如何分组的示例<ItemText>通过<ItemTextsType>对于每个单独<Item>所以结果将是这样的：

对于第一<Item>在这个例子中：

TYPE1

 description11 description12 

TYPE2

description21

description22

对于第二个Item在这个例子：

3型

 description31 description32 

TYPE2

description21

description22

当然，我会安排在像表中的结果：

<table width="100%" border="1" style="display: block;">
        <tbody>
            <tr>
                <td id="SelectedRowLinkageContents">

                            <tr>
                                <td>

                </td>
            </tr>
        </tbody>
    </table>

点是，有单独的分组对每个<Item>到它自己<table>和内部<table>有由groupping <ItemTextsType>

我已经试过类似

<xsl:key name="item-texts-type" match="ItemText" use="ItemTextsType" />


<xsl:for-each select="ItemTexts/ItemText[count(. | key('item-texts-type', ItemTextsType)[1]) = 1]">

                        <xsl:sort select="ItemTextsType" />
                        <tr>
                          <td style ="height:35px;font: bold; color:#507CD1;">
                            <xsl:value-of select="ItemTextsType" />
                          </td>
                        </tr>

                        <xsl:for-each select="key('item-texts-type', ItemTextsType)">
                          <tr>
                            <td>
                               <xsl:value-of select="ItemTextsTypeDesc" />
                            </td>
                          </tr>
                        </xsl:for-each>


                      </xsl:for-each>

但它只能在非重复性的工作节点（如果只有一个<Item> ，将工作的罚款）。 因为它来自客户我不能改变的XML。

请帮助我，我需要它尽快。

谢谢 ！！！！

Answer 1:

它仍然很难说有什么期望的解决方案是由于某些差异-例如，您输入的XML具有4 <Item>元素，但所需输出只需要其中3人进去。 此外，在您需要的输出数的描述不与输入XML文档中其预期的位置相匹配。

这就是说，如果我们专注于自己的既定期望的解决方案：

“意思是，有单独的分组对每个<Item>到它自己<table>和内部<table>有由groupping <ItemTextsType> ”

......那么这应该让你在正确的方向。

当这个XSLT：

<?xml version="1.0" encoding="utf-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
version="1.0">
  <xsl:output omit-xml-declaration="yes" indent="yes" />
  <xsl:strip-space elements="*" />

  <xsl:key
    name="kItemTextByType"
    match="ItemText"
    use="concat(generate-id(ancestor::Item[1]), '+', ItemTextsType)" />

  <xsl:template match="node()|@*">
    <xsl:copy>
      <xsl:apply-templates select="node()|@*" />
    </xsl:copy>
  </xsl:template>

  <xsl:template match="/*">
    <table width="100%" border="1" style="display: block;">
      <tbody>
        <tr>

          </td>
        </tr>
      </tbody>
    </table>
  </xsl:template>

  <xsl:template match="Item">

                 concat(generate-id(current()), '+', ItemTextsType)
