平面到分层 XML 转换 [英] Flat to hierarchical XML transformation
本文介绍了平面到分层 XML 转换的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
这是源 XML:
<CellData>
<Cell CellOrdinal="0">
<Value>actual</Value>
<FmtValue>actual</FmtValue>
</Cell>
<Cell CellOrdinal="1">
<Value>630961942</Value>
<FmtValue>630961942</FmtValue>
</Cell>
<Cell CellOrdinal="2">
<Value>2.045711422E7</Value>
<FmtValue>20457114.2200</FmtValue>
</Cell>
<Cell CellOrdinal="3">
<Value>9.997105219639378E1</Value>
<FmtValue>99.9711</FmtValue>
</Cell>
<Cell CellOrdinal="4">
<Value>3.33E1</Value>
<FmtValue>33.0000</FmtValue>
</Cell>
<Cell CellOrdinal="5">
<Value>2.046303782E7</Value>
<FmtValue>20463037.8200</FmtValue>
</Cell>
<Cell CellOrdinal="6">
<Value>deposit</Value>
<FmtValue>deposit</FmtValue>
</Cell>
<Cell CellOrdinal="7">
<Value>144783359</Value>
<FmtValue>144783359</FmtValue>
</Cell>
<Cell CellOrdinal="8">
<Value>2.1388E2</Value>
<FmtValue>213.8800</FmtValue>
</Cell>
<Cell CellOrdinal="9">
<Value>1.0452016063370595E-3</Value>
<FmtValue>0.0010</FmtValue>
</Cell>
<Cell CellOrdinal="10">
<Value>6.67E1</Value>
<FmtValue>67.0000</FmtValue>
</Cell>
<Cell CellOrdinal="11">
<Value>2.046303782E7</Value>
<FmtValue>20463037.8200</FmtValue>
</Cell>
<Cell CellOrdinal="12">
<Value>deposit</Value>
<FmtValue>deposit</FmtValue>
</Cell>
<Cell CellOrdinal="13">
<Value>304011203</Value>
<FmtValue>304011203</FmtValue>
</Cell>
<Cell CellOrdinal="14">
<Value>5.70972E3</Value>
<FmtValue>5709.7200</FmtValue>
</Cell>
<Cell CellOrdinal="15">
<Value>2.7902601999882342E-2</Value>
<FmtValue>0.0279</FmtValue>
</Cell>
<Cell CellOrdinal="16">
<Value>6.67E1</Value>
<FmtValue>67.0000</FmtValue>
</Cell>
<Cell CellOrdinal="17">
<Value>2.046303782E7</Value>
<FmtValue>20463037.8200</FmtValue>
</Cell>
</CellData>
此列表包含 6 列表格数据.数据按第 1 列排序并包含类型"，其顺序为:actual、accumulation、deposit 但有些可以根本不存在(例如累积).即它实际上包含这些数据:
This list contains 6-column table data.
Data is ordered by 1-st column and contain 'type', which will come in order: actual, accumulation, deposit but some can be absent at all (accumulation in example).
i.e. it's actually contain this data:
contract_type contract_id sum percentage contract_type_percentage balance_total
actual 630961942 20457114.2200 99.9711 33.0000 20463037.8200
deposit 144783359 213.8800 0.0010 67.0000 20463037.8200
deposit 304011203 5709.7200 0.0279 67.0000 20463037.8200
这是所需的 XML 输出(基于示例):
Here is desired XML output (based on example):
<body>
<actual_accounts>
<actual_account>
<contract_id>630961942</contract_id>
<sum>20457114.2200</sum>
<percentage>99.9711</percentage>
</actual_account>
<actual_percentage>33.0000</actual_percentage>
</actual_accounts>
<accumulation_accounts>
<accumulation_percentage>0</accumulation_percentage>
</accumulation_accounts>
<deposits>
<deposit>
<contract_id>144783359</contract_id>
<sum>213.8800</sum>
<percentage>0.0010</percentage>
</deposit>
<deposit>
<contract_id>304011203</contract_id>
<sum>5709.7200</sum>
<percentage>0.0279</percentage>
</deposit>
<deposit_percentage>67.0000</deposit_percentage>
</deposits>
<balance_total>20463037.8200</balance_total>
</body>
其中 *_percentage 标记应包含关联 * 集中任何行的第 5 列的值.
Where *_percentage tags should contain value of 5th column from any row from associated * set.
这是我到目前为止:

</xsl:if>
</xsl:if>
</xsl:template>

除了 *_percentage 标签之外的所有内容都可以.我仅限于 XSLT 1.0.
which do everything except whose *_percentage tags..
I'm limited to XSLT 1.0.

推荐答案
我更喜欢两步转换，首先将数据收集到一个变量中.当涉及大量数据时，可能必须重新考虑这一点.下面是一个可以解决问题的 xslt.
I would prefer a two step transformation, collecting the data into a variable first. When vast data size is involved, this may have to be reconsidered. Below is an xslt which does the trick.
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">
<xsl:output indent="yes" omit-xml-declaration="yes" method="xml" version="1.0"/>
<xsl:key name="CellGroup" use="@CellOrdinal - (@CellOrdinal mod 6)" match="CellData/Cell"/>
<xsl:template match="CellData">
<xsl:variable name="Cells">
<xsl:apply-templates select="Cell[generate-id() = generate-id(key('CellGroup', @CellOrdinal - (@CellOrdinal mod 6))[1])]" mode="group"/>
</xsl:variable>
<body>
<actual_accounts>
<xsl:for-each select="$Cells/Cell[contract-type='actual']">
<actual_account>
<xsl:copy-of select="contract-type"/>
<xsl:copy-of select="sum"/>
<xsl:copy-of select="percentage"/>
</actual_account>
</xsl:for-each>
<actual_percentage><xsl:value-of select="$Cells/Cell[contract-type='actual'][1]/contract-type-percentage"/></actual_percentage>
</actual_accounts>
<accumulation_accounts>
<xsl:for-each select="$Cells/Cell[contract-type='accumulation']">
<accumulation_account>
<xsl:copy-of select="contract-type"/>
<xsl:copy-of select="sum"/>
<xsl:copy-of select="percentage"/>
</accumulation_account>
</xsl:for-each>
<accumulation_percentage><xsl:value-of select="$Cells/Cell[contract-type='accumulation'][1]/contract-type-percentage[1]"/></accumulation_percentage>
</accumulation_accounts>
<deposits>
<xsl:for-each select="$Cells/Cell[contract-type='deposit']">
<deposit>
<xsl:copy-of select="contract-type"/>
<xsl:copy-of select="sum"/>
<xsl:copy-of select="percentage"/>
</deposit>
</xsl:for-each>
<deposit_percentage><xsl:value-of select="$Cells/Cell[contract-type='deposit'][1]/contract-type-percentage[1]"/></deposit_percentage>
</deposits>
<balance_total><xsl:value-of select="$Cells/Cell[1]/balance-total"/></balance_total>
</body>
</xsl:template>
<xsl:template match="Cell" mode="group">
<Cell>
<xsl:variable name="Cells" select="key('CellGroup', @CellOrdinal - (@CellOrdinal mod 6))"/>
<contract-type><xsl:value-of select="$Cells[1]/FmtValue"/></contract-type>
<contract-id><xsl:value-of select="$Cells[2]/FmtValue"/></contract-id>
<sum><xsl:value-of select="$Cells[3]/FmtValue"/></sum>
<percentage><xsl:value-of select="$Cells[4]/FmtValue"/></percentage>
<contract-type-percentage><xsl:value-of select="$Cells[5]/FmtValue"/></contract-type-percentage>
<balance-total><xsl:value-of select="$Cells[6]/FmtValue"/></balance-total>
</Cell>
</xsl:template>
</xsl:stylesheet>
我得到的输出如下:
<body>
<actual_accounts>
<actual_account>
<contract-type>actual</contract-type>
<sum>20457114.2200</sum>
<percentage>99.9711</percentage>
</actual_account>
<actual_percentage>33.0000</actual_percentage>
</actual_accounts>
<accumulation_accounts>
<accumulation_percentage></accumulation_percentage>
</accumulation_accounts>
<deposits>
<deposit>
<contract-type>deposit</contract-type>
<sum>213.8800</sum>
<percentage>0.0010</percentage>
</deposit>
<deposit>
<contract-type>deposit</contract-type>
<sum>5709.7200</sum>
<percentage>0.0279</percentage>
</deposit>
<deposit_percentage>67.0000</deposit_percentage>
</deposits>
<balance_total>20463037.8200</balance_total>
</body>
