在 XSLT 中处理多个同名元素
[英]Handling multiple elements with same name in XSLT
问题描述
I have xml with the following data.
我有包含以下数据的 xml。
<Rows>
<Header>
<sourcetable>Table_1</sourcetable>
<targettable>Table_2</targettable>
</Header>
<Table>
<Source_Fieldname>DTIME_INSERTED</Source_Fieldname>
<Source_Type>Timestamp</Source_Type>
<Source_Fieldname>ID_JOB</Source_Fieldname>
<Source_Type>String</Source_Type>
</Table>
<Header>
<sourcetable>Table_3</sourcetable>
<targettable>Table_4</targettable>
</Header>
<Table>
<Source_Fieldname>DTIME_INSERTED</Source_Fieldname>
<Source_Type>Timestamp</Source_Type>
<Source_Fieldname>ID_JOB</Source_Fieldname>
<Source_Type>String</Source_Type>
</Table>
</Rows>
I am trying to output this into separate tables per "Table" element just like this but can't figure it out since there are multiple elements with the same name.我试图将它输出到每个“表格”元素的单独表格中，就像这样，但无法弄清楚，因为有多个具有相同名称的元素。
So far this is what I got.到目前为止，这就是我得到的。
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" />
<xsl:template match="Row">
<table border="1px" cellpadding="3" cellspacing="1" style='font-family:"Calibri"; font-size:12; font-weight:"normal"' >
<tr align="center">
<xsl:for-each select="preceding-sibling::Header[1]">
<th colspan="4" bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="sourcetable" /> </font>
</th>
<th colspan="4" bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="targettable" /> </font>
</th>
</xsl:for-each>
<th bgcolor="#FFCCBC" rowspan="2">Flagfield</th>
</tr>
<tr align="left">
<td bgcolor="#C5E1A5">Source_Fieldname</td>
<td bgcolor="#C5E1A5">Source_Type</td>
</tr>
<xsl:for-each select=".">
<tr>
<xsl:for-each select="Source_Fieldname">
<td> <xsl:value-of select="."/> </td>
</xsl:for-each>
<xsl:for-each select="Source_Type">
<td> <xsl:value-of select="."/> </td>
</xsl:for-each>
</tr>
</xsl:for-each>
</xsl:for-each>
</table>
<br /><br/>
</xsl:template>
</xsl:stylesheet>
Any suggestion how to achieve desired output is appreciated.任何有关如何实现所需输出的建议表示赞赏。 Thanks!谢谢！

You had a good start but a few details were not working.你有一个良好的开端，但一些细节不起作用。 Here's how I would solve it.这是我将如何解决它。
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" />
<xsl:template match="/">
<html>
<head/>
<body>
<xsl:apply-templates select="Rows/Table"/>
</body>
</html>
</xsl:template>
<xsl:template match="Table">
<table border="1px" cellpadding="3" cellspacing="1" style='font-family:"Calibri"; font-size:12; font-weight:"normal"' >
<tr align="center">
<th bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="preceding-sibling::Header[1]/sourcetable" /> </font>
</th>
<th bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="preceding-sibling::Header[1]/targettable" /> </font>
</th>
</tr>
<tr align="left">
<td bgcolor="#C5E1A5">Source_Fieldname</td>
<td bgcolor="#C5E1A5">Source_Type</td>
</tr>
<xsl:apply-templates select="Source_Fieldname"/>
</table>
<br/><br/>
</xsl:template>
<xsl:template match="Source_Fieldname">
<tr>
<td> <xsl:value-of select="."/> </td>
<td> <xsl:value-of select="following-sibling::Source_Type[1]"/> </td>
</tr>
</xsl:template>
</xsl:stylesheet>

So far I managed to create the desired outcome, but however, I would seriously suggest to sanitize your XML file/input, because it's complicating things.到目前为止，我设法创建了所需的结果，但是，我会认真建议清理您的 XML 文件/输入，因为它使事情复杂化。
But with your current file, you can use this XSLT-1.0 stylesheet to get the desired output:但是对于您当前的文件，您可以使用此 XSLT-1.0 样式表来获得所需的输出：
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="html" indent="yes" />
<!-- A template handling the main HTML stuff -->
<xsl:template match="/Rows">
<html>
<body>
<font size="2" face="Calibri" >
<h1>The following Source - Target Tables have DDL Mismatch(es)</h1>
<br />
<xsl:apply-templates select="Table" />
</font>
</body>
</html>
</xsl:template>
<xsl:template match="Table">
<table border="1px" cellpadding="3" cellspacing="1" style='font-family:"Calibri"; font-size:12; font-weight:"normal"' >
<tr align="center">
<xsl:for-each select="preceding-sibling::Header[1]">
<th colspan="1" bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="sourcetable" /> </font>
</th>
<th colspan="1" bgcolor="#ccffff">
<font size="2" face="Calibri" style="text-transform:uppercase"> <xsl:value-of select="targettable" /> </font>
</th>
</xsl:for-each>
<th bgcolor="#FFCCBC" rowspan="2">Flagfield</th>
</tr>
<tr align="left">
<td bgcolor="#C5E1A5">Source_Fieldname</td>
<td bgcolor="#C5E1A5">Source_Type</td>
</tr>
<xsl:for-each select="*[local-name()='Source_Fieldname']">
<tr>
<td><xsl:value-of select="."/></td>
<td><xsl:value-of select="following-sibling::Source_Type[1]"/></td>
</tr>
</xsl:for-each>
</table>
<br /><br/>
</xsl:template>
</xsl:stylesheet>
The central aspect is the xsl:for-each loop:核心方面是xsl:for-each循环：
<xsl:for-each select="*[local-name()='Source_Fieldname']">
<tr>
<td><xsl:value-of select="."/></td>
<td><xsl:value-of select="following-sibling::Source_Type[1]"/></td>
</tr>
</xsl:for-each>
The output is:输出是：
It simply iterates over all <Table> children which are named Source_Fieldname and then creates a table cell for these and for the first following-sibling Source_Type element.它只是遍历所有名为Source_Fieldname <Table>子Source_Fieldname ，然后为这些元素和第一个后续兄弟Source_Type元素创建一个表格单元格。 This does work for a two element table, but it should be no problem to extend it to a several children situation.这确实适用于两元素表，但将其扩展到多个子项的情况应该没有问题。
