【中文标题】如何使用 XSLT 正确删除 XML 标记【英文标题】：How to properly remove an XML tag using XSLT 【发布时间】：2021-09-17 01:43:04 【问题描述】：我有一个如下的 XML 文档
<?xml version='1.0' encoding='UTF-8'?>

<UNIT_PRICE_IN_OUR_CURRENCY>1073.4</UNIT_PRICE_IN_OUR_CURRENCY>
<UNIT_PRICE_IN_SUPPLIER_CURRENCY>1073.4</UNIT_PRICE_IN_SUPPLIER_CURRENCY>
<VENDOR_PART_NO>010008002010</VENDOR_PART_NO>
</STA_ORDER_LINE>
</STA_ORDER_LINES>
</STA_ORDERS>
我需要一个 XSL 文档来传输上述 xml，以便如果版本号只有一个数字，
示例 3 => 03, 2 => 02, 10 => 10（10 已经有 2 个数字，所以我们保持原样）
我用过下面的xsl。
<?xml version='1.0' encoding='UTF-8'?>
<xsl:stylesheet xmlns:ifs="urn:ifsworld-com:schemas:TYPE_SCHEMA_NAME_HERE" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:date="http://exslt.org/dates-and-times" version="1.0" exclude-result-prefixes="ifs date">
<xsl:output method="xml" indent="yes"/>
<xsl:template match="STA_ORDER_LINE">
<xsl:choose>
<xsl:when test="(RELEASE_NO > 9)">
<xsl:apply-templates select="@*|node()" />
</xsl:when>
<xsl:otherwise>
<xsl:apply-templates select="@*|node()" />
<RELEASE_NO>
<xsl:value-of select="concat('0',RELEASE_NO)"/>
</RELEASE_NO>
</xsl:otherwise>
</xsl:choose>
</xsl:template>
</xsl:stylesheet>
但似乎无法正常工作，因为它添加了带有更正的新标签，但旧标签似乎仍然可用。 (https://www.freeformatter.com/xsl-transformer.html)
有什么想法吗？？

【问题讨论】：
【参考方案1】：以下对我有用：
<xsl:choose>
<xsl:when test='/STA_ORDERS/STA_ORDER_LINES/STA_ORDER_LINE/RELEASE_NO > 9'>
<RELEASE_NO>
<xsl:value-of select="/STA_ORDERS/STA_ORDER_LINES/STA_ORDER_LINE/RELEASE_NO"/>
</RELEASE_NO>
</xsl:when>
<xsl:otherwise>
<RELEASE_NO>
<xsl:value-of select="concat('0',/STA_ORDERS/STA_ORDER_LINES/STA_ORDER_LINE/RELEASE_NO)"/>
</RELEASE_NO>
</xsl:otherwise>
</xsl:choose>
【讨论】：
【参考方案2】：请尝试以下 XSLT。
它考虑了一个默认命名空间。
XSLT
<?xml version="1.0"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns1="urn:ifsworld-com:schemas:outbound_distribution_transactions_sta_send_purchase_order_sta_request">
<xsl:output method="xml" encoding="utf-8" indent="yes" omit-xml-declaration="no"/>
<xsl:strip-space elements="*"/>
<xsl:template match="@*|node()">
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="ns1:RELEASE_NO[string-length() = 1]">
<xsl:copy>
<xsl:value-of select="concat('0', .)"/>
</xsl:copy>
</xsl:template>
</xsl:stylesheet>

非常感谢。它完美地工作。你确实是一个救生员：D 修订后的 XML 似乎不起作用。我只在 xmlns:xsi="w3.org/2001/XMLSchema-instance" xmlns="urn:ifsworld-com:schemas:outbound_distribution_transactions_sta_send_purchase_order_sta_request" 下面添加到它失败了，因为您要处理内容两次，一次使用 xsl:value of，一次使用 apply-templates
<xsl:apply-templates select="@*|node()" />
<RELEASE_NO>
<xsl:value-of select="concat('0',RELEASE_NO)"/>
</RELEASE_NO>
但是有很多更简洁的方法可以做到这一点。伊扎克给你看了一个；另一个是使用format-number(RELEASE_NO, '00')；另一种（相当偷偷摸摸的）方式是substring(string(RELEASE_NO + 100)), 2)。

谢谢迈克尔。对修订后的 XML 的任何想法似乎都不起作用。 如果您有新问题，请将其作为新问题提出，而不是作为对先前问题的修改。当您这样做时，任何人都无法将问题和答案联系起来。另外，请不要告诉我们某事“不起作用”而不告诉我们它是如何失败的——据我们所知，它产生了正确的答案，但您的期望是错误的。 注意到@MichaelKay。谢谢以上是关于如何使用 XSLT 正确删除 XML 标记的主要内容，如果未能解决你的问题，请参考以下文章
