[英]Merge Elements (XML) With Same ID to txt file using XSLT
I have a task where I need to loop through an XML document and merge elements/nodes with the same ID.我有一个任务,我需要遍历 XML 文档并合并具有相同 ID 的元素/节点。 The output should be a csv file (for further processing) where each line have a fixed length. output 应该是 csv 文件(用于进一步处理),其中每行具有固定长度。 Based on the values of the nodes, that value needs to be placed at a certain location in the output.根据节点的值,该值需要放置在 output 中的某个位置。
Here is a sample of the XML :这是XML 的示例:
<root>
<User>
<UserID>55555</UserID>
<Value>Active</Value>
</User>
<User>
<UserID>55555</UserID>
<Value>Admin</Value>
</User>
<User>
<UserID>55555</UserID>
<Value>Eligible</Value>
</User>
<User>
<UserID>123456</UserID>
<Value>Active</Value>
</User>
</root>
My desired output would be:我想要的 output将是:
User ID, Active, Admin, Eligible
55555, Y, Y, Y,
123456, Y, N, N,
NOTE the values are ALWAYS THE SAME (Active, Admin & Eligible), but Users can have different amount of values like in the example.请注意,这些值始终相同(活动、管理员和合格),但用户可以有不同数量的值,如示例中所示。
Currently this is what I got:目前这是我得到的:
<xsl:template match="/root">
<Header>
<xsl:text>User ID</xsl:text>
<xsl:value-of select="$comma"/>
<xsl:text>Active</xsl:text>
<xsl:value-of select="$comma"/>
<xsl:text>Admin</xsl:text>
<xsl:value-of select="$comma"/>
<xsl:text>Eligible</xsl:text>
<xsl:text>
</xsl:text>
</Header>
<xsl:for-each-group select="User" group-by="UserID">
<!-- User ID -->
<xsl:value-of select="UserID"/>
<xsl:value-of select="$comma"/>
<xsl:for-each-group select="current-group()" group-by="Value">
<xsl:value-of select="current-grouping-key()"/>
<xsl:value-of select="$comma"/>
</xsl:for-each-group>
<xsl:value-of select="$lineFeed"/>
</xsl:for-each-group>
</xsl:template>
This group and selects the correct elements, but then I need to place them under the correct headers (like axample with desired output).该组并选择正确的元素,但随后我需要将它们放在正确的标题下(例如具有所需输出的 axample)。
Can anyone point me in the right direction here?谁能在这里指出我正确的方向? Any help would be much appreciated.任何帮助将非常感激。
If I understand this correctly (very big if,): you want to do something like:如果我理解正确(如果,非常大):你想做类似的事情:
XSLT 2.0 XSLT 2.0
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="/root">
<!-- header -->
<xsl:text>User ID, Active, Admin, Eligible </xsl:text>
<!-- rows -->
<xsl:for-each-group select="User" group-by="UserID">
<!-- User ID -->
<xsl:value-of select="UserID"/>
<xsl:text>, </xsl:text>
<!-- Active -->
<xsl:value-of select="if (current-group()/Value[.='Active']) then 'Y' else'N'"/>
<xsl:text>, </xsl:text>
<!-- Admin -->
<xsl:value-of select="if (current-group()/Value[.='Admin']) then 'Y' else'N'"/>
<xsl:text>, </xsl:text>
<!-- Eligible -->
<xsl:value-of select="if (current-group()/Value[.='Eligible']) then 'Y' else'N'"/>
<xsl:text> </xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
Or more compactly:或者更简洁:
<xsl:stylesheet version="2.0"
xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output method="text" encoding="UTF-8" />
<xsl:template match="/root">
<!-- header -->
<xsl:text>User ID, Active, Admin, Eligible </xsl:text>
<!-- rows -->
<xsl:for-each-group select="User" group-by="UserID">
<xsl:value-of select="UserID, for $t in ('Active', 'Admin', 'Eligible') return if (current-group()/Value[.=$t]) then 'Y' else 'N'" separator=", "/>
<xsl:text> </xsl:text>
</xsl:for-each-group>
</xsl:template>
</xsl:stylesheet>
Note that the result is slightly different from the one you posted: there is no trailing comma in each record.请注意,结果与您发布的结果略有不同:每条记录中没有尾随逗号。
