是否由于格式无效导致XSL转换失败？

Question

我尝试从cbc:ID元素中删除字符NO，但仅在找到这些字符的文件中删除。

<cbc:ID>NO123456789</cbc:ID>

应该变成：

<cbc:ID>123456789</cbc:ID>

我已经取得了一些进展，但遇到了障碍，我可以看到我做错了什么。XSL工具插件抱怨Notepad++无效。

我对您的要求的解释是“我正在尝试从cbc:ID元素中删除字符NO ...”下面是样式表解决方案。只需要替换一次，其余的可以通过复制模板来处理：

<xsl:stylesheet version="2.0" 
    xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2">
    <xsl:output method="xml" indent="yes"/>

    <xsl:template match="//cbc:ID" priority="2">
        <xsl:copy>
            <xsl:value-of select="replace(.,'NO','')"/>
        </xsl:copy>
    </xsl:template>

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

以下是将xslt应用于xml时的结果：

<?xml version="1.0" encoding="UTF-8"?>
<Invoice xmlns="urn:oasis:names:specification:ubl:schema:xsd:Invoice-2"
   xmlns:ext="urn:oasis:names:specification:ubl:schema:xsd:CommonExtensionComponents-2"
   xmlns:cbc="urn:oasis:names:specification:ubl:schema:xsd:CommonBasicComponents-2"
   xmlns:cac="urn:oasis:names:specification:ubl:schema:xsd:CommonAggregateComponents-2"
   xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
   <cac:PaymentMeans>
      <cbc:PaymentMeansCode>31</cbc:PaymentMeansCode>
      <cac:PayeeFinancialAccount>
         <cbc:ID>60210517971</cbc:ID>
      </cac:PayeeFinancialAccount>
   </cac:PaymentMeans>
</Invoice>
