XSLT将xml中的多个相同节点处理成一行

Question

我是Xslt的新手，我想处理具有两个相同节点但只有一个不同属性的XML。根据不同的属性输出应该在同一行有两个不同的列。 如果数据集ID具有8位数字它应该进入“集ID 1”列&如果它始于10位数字它应该去“集ID 2”列 这里开始是XML-

我期待像

Name ID DatasetId1 DatasetId2 
DEM 8888431618 31661449AA 8888431618A 
CEM 8888516207 31661809AB 8888516207/C 

Answer 1

输出如果数据集ID与8位数字就应该进入“集ID 1” &列开始，如果它开始与10位数字就应该到 “集ID 2”列

与制剂中的问题是，如果字符串与10位数字开头，则根据定义它也开始以8位的数字。所以，假设这些是唯一的两种可能性，测试应该集中在第9个字符是否是数字。

以下内容还假定行按连续对排列，共有Id。

XSLT 1.0

<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>

<xsl:template match="/DisplayDefinitionTable"> 
    <table> 
    <tr> 
     <th>Name</th>

    </tr> 
    <xsl:for-each select="rows/row[position() mod 2 = 1]">

      <!-- 8 digits --> 
      <td> 
       <xsl:value-of select="$datasetIDs[not(contains('', substring(., 9, 1)))]"/> 
      </td> 
      <!-- 10 digits --> 
      <td> 
       <xsl:value-of select="$datasetIDs[contains('', substring(., 9, 1))]"/> 
      </td> 
     </tr> 
    </xsl:for-each> 
    </table> 
</xsl:template> 

</xsl:stylesheet> 

应用到你的输入例子，结果将是：

<?xml version="1.0" encoding="UTF-8"?> 
<table> 
    <tr> 
    <th>Name</th> 
    <th>ID</th> 
    <th>DatasetId 1</th> 
    <th>DatasetId 2</th> 
    </tr> 
    <tr> 
    <td>DEM</td> 
    <td>8888431618</td> 
    <td>31661449AA</td> 
    <td>8888431618A</td> 
    </tr> 
    <tr> 
    <td>CEM</td> 
    <td>8888516207</td> 
    <td>31661809AB</td> 
    <td>8888516207/C</td> 
    </tr> 
    <tr> 
    <td>TT</td> 
    <td>8888574081</td> 
    <td>31691071/AC</td> 
    <td>8888574081/C</td> 
    </tr> 
</table> 

呈现为：
