我有一个使用wix-toolset的heat.exe生成的XML文件。这会将每个<File>对象包装在<Component>内。 我必须使用XSLT v1.0对其进行修改，以便<File>所有@Source包含相同FileName（不带扩展名）的<Component>应提取到一个@Source。通常，<File>仅以＆＃34; .dll＆＃34;结尾。或＆＃34; .config＆＃34;。

以“

”结尾的@KeyPath附加内容
  • ＆＃34;的.config＆＃34;应将@Assembly设置为＆＃34;否＆＃34;
  • ＆＃34;的.dll＆＃34;应该有一个额外的属性<?xml version="1.0" encoding="utf-8"?> <Wix xmlns="http://schemas.microsoft.com/wix/2006/wi"> <Fragment> <DirectoryRef Id="GAC35"> <Component Id="cmp5BC59A7DCA65D1B974894AAA758DB693" Guid="{1A2AC82E-7AD9-4CB6-BF42-4D31FAD7786E}"> <File Id="filE7FFE881A5ECF045432F46FBA78AEDD4" KeyPath="yes" Source="$(var.HarvestLoggingGac35Policy)\Policy.1.0.Logging.config" /> </Component> <Component Id="cmp7F80B805A2BDCF92241FB8019B91FF1C" Guid="{0F88D7E9-355A-40C1-AC8C-29BBB27690FB}"> <File Id="filB35F1D68CCC038864F21E76D8A9F5977" KeyPath="yes" Source="$(var.HarvestLoggingGac35Policy)\Policy.1.0.Logging.dll" /> </Component> <Component Id="test1" Guid="{1A2AC82E-7AD9-4CB6-BF42-4D31FAD7786E}"> <File Id="filE7FFE881A5ECF045432F46FBA78AEDD4" KeyPath="yes" Source="$(var.HarvestLoggingGac35Policy)\Policy.2.0.Logging.config" /> </Component> <Component Id="test12" Guid="{0F88D7E9-355A-40C1-AC8C-29BBB27690FB}"> <File Id="filB35F1D68CCC038864F21E76D8A9F5977" KeyPath="yes" Source="$(var.HarvestLoggingGac35Policy)\Policy.2.0.Logging.dll" /> </Component> </DirectoryRef> </Fragment> <Fragment> <ComponentGroup Id="HeatGenerated_Gac35Policies"> <ComponentRef Id="cmp5BC59A7DCA65D1B974894AAA758DB693" /> <ComponentRef Id="cmp7F80B805A2BDCF92241FB8019B91FF1C" /> <ComponentRef Id="test1" /> <ComponentRef Id="test2" /> </ComponentGroup> </Fragment> </Wix> ，其值为＆＃34; .net＆＃34;

以下是必须转换的XML I示例：

<Wix xmlns="http://schemas.microsoft.com/wix/2006/wi">
<Fragment>
  <DirectoryRef Id="GAC35">
     <Component Id="cmp5BC59A7DCA65D1B974894AAA758DB693"
                Guid="{1A2AC82E-7AD9-4CB6-BF42-4D31FAD7786E}">
        <File Id="filE7FFE881A5ECF045432F46FBA78AEDD4"
              KeyPath="no"
              Source="$(var.HarvestLoggingGac35Policy)\Policy.1.0.Logging.config"/>
        <File Id="filB35F1D68CCC038864F21E76D8A9F5977"
              KeyPath="yes"
              Source="$(var.HarvestLoggingGac35Policy)\Policy.1.0.Logging.dll"
              Assembly=".net"/>
     </Component>
     <Component Id="test1"
                Guid="guid1">
        <File Id="filE7FFE881A5ECF045432F46FBA78AEDD4"
              KeyPath="no"
              Source="$(var.HarvestLoggingGac35Policy)\Policy.2.0.Logging.config"/>
        <File Id="filB35F1D68CCC038864F21E76D8A9F5977"
              KeyPath="yes"
              Source="$(var.HarvestLoggingGac35Policy)\Policy.2.0.Logging.dll"
              Assembly=".net"/>
     </Component>
  </DirectoryRef>
</Fragment>
<Fragment>
  <ComponentGroup Id="HeatGenerated_Gac35Policies">

那么这应该是XSL v1的预期输出：

编辑：这是我自己的最后一个＆＃34;解决方案＆＃34; （不完整）直到我使用了@ michael.hor257k的答案

import json
results = []
# Your loop
foreach element in elements:
    element_json_object = ... # Construct a JSON object here
    results.append(element_json_object)

data = {
    "results": results
}

with open('data.json', 'w') as outfile:
    json.dump(data, outfile)

1 个答案:

答案 0 :(得分：1)

您无法通过他们没有的东西对节点进行分组。如果要按不带扩展名的文件名对组件进行分组，则必须首先将这样的值添加到每个组件 - 作为元素或属性。这是因为在XSLT 1.0中删除扩展名并不简单，并且无法通过单个XPath表达式来完成。

完成后，您可以继续将Muenchian分组应用于中期结果：

XSLT 1.0

<xsl:template match="@*|node()">

附录：

如果您可以放心地认为扩展程序将始终为.dll或.config，那么您可以将其简化为：

XSLT 1.0 

<xsl:stylesheet version="1.0"

xmlns:wix="http://schemas.microsoft.com/wix/2006/wi">
<xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
<xsl:strip-space elements="*"/>

<xsl:key name="k" match="wix:Component" use="substring-before(concat(substring-before(concat(wix:File/@Source, '.dll'), '.dll'), '.config'), '.config')"/>

<!-- identity transform -->
<xsl:template match="@*|node()">
    <xsl:copy>
        <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
</xsl:template>

<xsl:template match="wix:DirectoryRef">
    <xsl:copy>
        <xsl:copy-of select="@*"/>
        <xsl:for-each select="wix:Component[count(. | key('k', substring-before(concat(substring-before(concat(wix:File/@Source, '.dll'), '.dll'), '.config'), '.config'))[1]) = 1]">

                <xsl:copy-of select="key('k', substring-before(concat(substring-before(concat(wix:File/@Source, '.dll'), '.dll'), '.config'), '.config'))/wix:File"/>
