如何在不改变结构的情况下去除某些部分
How to remove certain parts without changing the structure
让我们看看我是否可以重新表述这个问题....
我有一些大 XML 文件，我想在不更改日期结构的情况下从中删除某些数据。
如果您查看下面的源代码 XML，您会发现在不同的层级都有“单一部件”，
parts/assembly/mainpart/proxy/singlepart
或者只是
parts/mainpart/proxy/singlepart
每个单件中都有一个零件。当部件的名称以特定单词开头或具有特定值的角色时，我希望将单个部件排除在外。在所有其他方面，文件应该保持不变。

抱歉，如果它们很长，我已尝试删除大部分数据，但需要留下一些以显示结构。我找不到如何附加示例文件。我已经试着格式化清楚了。
正如我所说，我的 XSLT 返回 XML，没有不需要的部分，但也没有“程序集”级别。如果可能的话，我想要一种更简单的方式来表示跳过不需要的部分。
谢谢。
你的问题后的评论听起来好像 <xsl:template match="mainpart//singlepart"/> 加上身份转换模板就是你 need/want。
在你编辑之后，根据你的解释，我认为你想要身份转换加上一个空模板用于你想要成为 removed/omitted 的元素（singlepart？）例如
<xsl:template match="singlepart[part/section/@key[starts-with(.,'AGBrown')
or
starts-with(.,'Albion')
or
starts-with(.,'Ayrshire')
or
starts-with(.,'BWIndustries')
or
starts-with(.,'Hi Span')
or
starts-with(.,'HiSpan')
or
starts-with(.,'Kingspan')
or
starts-with(.,'Usr Kingspan')
or
starts-with(.,'KSB')
or
starts-with(.,'KSP')
or
starts-with(.,'Metsec')
or
starts-with(.,'BWIndustries')
or
starts-with(.,'Steadmans')
or
starts-with(.,'Usr Steel Sections')
or
starts-with(.,'Steel Sections')
or
starts-with(.,'Tegral')
or
starts-with(.,'ThomasPanels')
or
starts-with(.,'Usr Thomas Panels')
or
starts-with(.,'Ultra')
or
starts-with(.,'Usr Ultra')] or part/role/@key[starts-with(., 'Cladding_profile')]]"/>
身份转换模板是
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
让我们看看我是否可以重新表述这个问题....
我有一些大 XML 文件，我想在不更改日期结构的情况下从中删除某些数据。
如果您查看下面的源代码 XML，您会发现在不同的层级都有“单一部件”，
parts/assembly/mainpart/proxy/singlepart
或者只是
parts/mainpart/proxy/singlepart
每个单件中都有一个零件。当部件的名称以特定单词开头或具有特定值的角色时，我希望将单个部件排除在外。在所有其他方面，文件应该保持不变。

抱歉，如果它们很长，我已尝试删除大部分数据，但需要留下一些以显示结构。我找不到如何附加示例文件。我已经试着格式化清楚了。
正如我所说，我的 XSLT 返回 XML，没有不需要的部分，但也没有“程序集”级别。如果可能的话，我想要一种更简单的方式来表示跳过不需要的部分。
谢谢。
你的问题后的评论听起来好像 <xsl:template match="mainpart//singlepart"/> 加上身份转换模板就是你 need/want。
在你编辑之后，根据你的解释，我认为你想要身份转换加上一个空模板用于你想要成为 removed/omitted 的元素（singlepart？）例如
<xsl:template match="singlepart[part/section/@key[starts-with(.,'AGBrown')
or
starts-with(.,'Albion')
or
starts-with(.,'Ayrshire')
or
starts-with(.,'BWIndustries')
or
starts-with(.,'Hi Span')
or
starts-with(.,'HiSpan')
or
starts-with(.,'Kingspan')
or
starts-with(.,'Usr Kingspan')
or
starts-with(.,'KSB')
or
starts-with(.,'KSP')
or
starts-with(.,'Metsec')
or
starts-with(.,'BWIndustries')
or
starts-with(.,'Steadmans')
or
starts-with(.,'Usr Steel Sections')
or
starts-with(.,'Steel Sections')
or
starts-with(.,'Tegral')
or
starts-with(.,'ThomasPanels')
or
starts-with(.,'Usr Thomas Panels')
or
starts-with(.,'Ultra')
or
starts-with(.,'Usr Ultra')] or part/role/@key[starts-with(., 'Cladding_profile')]]"/>
身份转换模板是
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
