我想迭代一棵树,找到共同的元素文本,并能够在表格中显示。
<Root>
<attr>
<attrlabl>Attribute Label 1</attrlabl>
<attrdef>Attribute Definition 1</attrdef>
<attrdomv>
<edom>
<edomv>O</edomv>
<edomd>Open</edomd>
</edom>
<edom>
<edomv>C</edomv>
<edomd>Close</edomd>
</edom>
</attrdomv>
</attr>
<attr>
<attrlabl>Attribute Label 2</attrlabl>
<attrdef>Attribute Definition 2</attrdef>
<attrdomv>
<edom>
<edomv>O</edomv>
<edomd>Open</edomd>
</edom>
<edom>
<edomv>C</edomv>
<edomd>Close</edomd>
</edom>
</attrdomv>
</attr>
<attr>
<attrlabl>Attribute Label 3</attrlabl>
<attrdef>Attribute Definition 3</attrdef>
<attrdomv>
<udom>
<udomv>No display</udomv>
</udom>
</attrdomv>
</attr>
<attr>
<attrlabl>Attribute Label 4</attrlabl>
<attrdef>Attribute Definition 4</attrdef>
<attrdomv>
<edom>
<edomv>D</edomv>
<edomd>Different</edomd>
</edom>
</attrdomv>
</attr>
</Root>
输出应该类似于这样,其中只显示公共元素文本。任何帮助将不胜感激!
<tr>
<td> For Attribute Label 1 and 2</td>
</tr>
<tr>
<td> Value: O </td>
<td> Description: Open </td>
</tr>
<tr>
<td> Value: C </td>
<td> Description: Close </td>
答案 0 :(得分:1)
尝试以下几点:
XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="xml" omit-xml-declaration="yes" version="1.0" encoding="utf-8" indent="yes"/>
<xsl:template match="/Root">
<table border="1">
<xsl:for-each-group select="attr/attrdomv/edom" group-by="edomv">
<xsl:if test="count(current-group()) > 1">
<tr>
<td>
<xsl:value-of select="current-group()/ancestor::attr/attrlabl" separator=", "/>
</td>
<td>
<xsl:text>Value: </xsl:text>
<xsl:value-of select="current-grouping-key()"/>
</td>
<td>
<xsl:text>Description: </xsl:text>
<xsl:value-of select="current-group()[1]/edomd"/>
</td>
</tr>
</xsl:if>
</xsl:for-each-group>
</table>
</xsl:template>
</xsl:stylesheet>
结果应用于您的示例输入时,与您的结果略有不同:
<table border="1">
<tr>
<td>Attribute Label 1, Attribute Label 2</td>
<td>Value: O</td>
<td>Description: Open</td>
</tr>
<tr>
<td>Attribute Label 1, Attribute Label 2</td>
<td>Value: C</td>
<td>Description: Close</td>
</tr>
</table>
主要是因为我认为祖先的身份不过是巧合。
