问题描述
我的 XSLT 转换有一个小问题.
I'm having a slight problem with my XSLT transform.
我有以下 XSLT；
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0"><!-- removes the unrelated elements -->
<xsl:template match="@* | node()">
<xsl:copy>
<xsl:apply-templates select="@* | node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="master_version[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="press_section[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="version[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="task_info_press_section[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="task_info_post_press[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="post_press_version[not(ORDER = //order/ORDERPK)]"/>
<!-- removes specified nodes from all elements -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ORDER"/>
<xsl:template match="ORDERPK"/>
<xsl:template match="PRESS_x0020_SECTION"/>
<xsl:template match="POST_x0020_PRESS"/>
<!-- Creates attributes against the ORDER element -->
<xsl:strip-space elements="*"/>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="order">
<order job_id="{job_id}" site_code="{site_code}" replace="{replace}">
<xsl:apply-templates/>
</order>
</xsl:template>
<xsl:template match="job_id | site_code | replace | master_version"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="order">
<order job_id="{@job_id}" site_code="{@site_code}" replace="{Replace}">
<xsl:apply-templates select="node()"/>
<xsl:copy-of select="../master_version"/>
</order>
</xsl:template>
<xsl:template match="Replace | master_version"/>
<!-- renames element to specified name -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="task_info_press_section">

</xsl:element>
</xsl:template>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="task_info_post_press">
<xsl:element name="task_info2">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
这是我转换前的原始XML；

master_version"元素应该在转换之后嵌套，确实如此，但是如果master_version"中的ORDER"节点不等于中的ORDERPK"，转换也告诉它删除所有元素订单"，它似乎没有这样做.
The "master_version" element should be nested after the transform, which it is, but the transform is also telling it to delete all the element if the "ORDER" node in "master_version" is not equal to "ORDERPK" in "order", which it doesn't appear to be doing.
有什么想法吗?
我还被告知我的 XSLT 格式不太好，有人可以帮忙吗?
Also I have been told that my XSLT isn't formatted very well, could anybody possibly help with that?
推荐答案
您的 XSLT 存在许多问题.专注于手头的问题，一个问题是您的订单"模板之一使用了 xsl:copy-of
There are a number of issues with your XSLT. Focusing on the problem in hand, one issue is in one of your "order" templates uses an xsl:copy-of
<xsl:template match="order">
<order job_id="{@job_id}" site_code="{@site_code}" replace="{Replace}">
<xsl:apply-templates select="node()"/>
<xsl:copy-of select="../master_version"/>
</order>
</xsl:template>
在继续之前，您有两个模板匹配订单".严格来说，这在 XSLT 中被指定为错误.您实际上可能不会看到错误，因为某些处理器会忽略重复的模板，而只使用最后一个.你应该删除第一个.
Before going further though, you have two templates matching "order". This is strictly speaking specified as an error in XSLT. You may not actually be seeing an error because some processors ignore the duplicate templates, and only use the last one. You should delete the first one.
无论如何，通过使用 xsl:copy-of 它只是简单地复制这里的所有 master_version 元素，而不管这里是否有任何其他模板匹配.您需要使用 xsl:apply-templates
Anyway, by using xsl:copy-of it is simply going to copy all master_version elements here, regardless of any other template matches here. You need to use xsl:apply-templates
<xsl:template match="order">
<order job_id="{@job_id}" site_code="{@site_code}" replace="{Replace}">
<xsl:apply-templates select="node()"/>
<xsl:apply-templates select="../master_version"/>
</order>
</xsl:template>
但是由于这两个模板匹配，这本身不起作用(尽管必须模板都匹配仅 master_version 如上所述)
But this on its own will not work because of these two template matches (although it is an error to have to templates both matching just master_version as mentioned)
<xsl:template match="job_id | site_code | replace | master_version"/>
<xsl:template match="Replace | master_version"/>
从这些模板匹配中删除master_version，只保留现有的
Remove the master_version from these template matches, and leave just this existing one
<xsl:template match="master_version[not(ORDER = //order/ORDERPK)]"/>
(请注意，当一个元素与条件匹配时，它实际上比刚匹配master_version 的元素具有更高的优先级，因此在这种情况下这不是错误).
(Note that when an element is matched with a condition, it will actually have a higher priority than one that just matched master_version, so this is not an error in this instance).
此时您也会在那里，但现在您会发现 master_version 仍会在其当前位置输出.为了解决这个问题，你可以有一个模板匹配 dataroot 并添加代码以显式忽略该点的 master_version 元素
You would also be there at this point, but you would find now that master_version would still be output in their current place too. To get around this, you can have a template matching dataroot and add code to explicitly ignore the master_version elements at that point
<xsl:template match="dataroot">
<xsl:copy>
<xsl:apply-templates select="@*|node()[not(self::master_version)]"/>
</xsl:copy>
</xsl:template>
试试这个 XSLT.它可能无法提供您指定的精确输出，但它应该可以解决您询问的 master_version 元素上的问题:
Try this XSLT. It may not give the precise output you specified, but it should solve the problem on your master_version elements which you asked about:
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
<xsl:template match="master_version[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="press_section[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="version[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="task_info_press_section[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="task_info_post_press[not(ORDER = //order/ORDERPK)]"/>
<xsl:template match="post_press_version[not(ORDER = //order/ORDERPK)]"/>
<!-- removes specified nodes from all elements -->
<xsl:template match="ORDER"/>
<xsl:template match="ORDERPK"/>
<xsl:template match="PRESS_x0020_SECTION"/>
<xsl:template match="POST_x0020_PRESS"/>
<!-- Creates attributes against the ORDER element -->
<xsl:strip-space elements="*"/>
<xsl:output method="xml" indent="yes"/>
<xsl:template match="dataroot">
<xsl:copy>
<xsl:apply-templates select="@*|node()[not(self::master_version)]"/>
</xsl:copy>
</xsl:template>
<xsl:template match="job_id | site_code | replace | Replace"/>
<!-- identity transform -->
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="order">
<order job_id="{@job_id}" site_code="{@site_code}" replace="{Replace}">
<xsl:apply-templates select="node()"/>
<xsl:apply-templates select="../master_version"/>
</order>
</xsl:template>
<xsl:template match="task_info_press_section">
<xsl:element name="task_info1">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
<xsl:template match="task_info_post_press">
<xsl:element name="task_info2">
<xsl:apply-templates/>
</xsl:element>
</xsl:template>
</xsl:stylesheet>
另请注意，Daniel Haley 在评论中提到的多个身份模板已被删除.
Also note the multiple identity templates have been removed, as mentioned by Daniel Haley in comments.
