使用XSLT为现有命名空间添加额外命名空间并移除ns0前缀求助

Let's break down what's wrong with your current XSLT and fix it to get your desired output:

Issues with Your Original XSLT #

• You tried to copy schemaLocation as a namespace node, but xsi:schemaLocation is an attribute, not a namespace. The namespace::schemaLocation selector doesn't exist, so that line does nothing.
• Your root element template didn't explicitly add the required attributes; it only copied existing ones, which is why the new attributes never appeared.

Corrected XSLT Code #

This solution will add the required namespace and schema location attributes, while preserving all other content and removing any unnecessary prefixes (like ns0 if present):

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:doc="urn:iso:std:iso:20022:tech:xsd:camt.053.001.02">
  <xsl:output method="xml" version="1.0" encoding="UTF-8" indent="yes"/>
  
  <!-- Identity template: copies all nodes/attributes by default (preserves existing content) -->
  <xsl:template match="@*|node()">
    <xsl:copy>
      <xsl:apply-templates select="@*|node()"/>
    </xsl:copy>
  </xsl:template>
  
  <!-- Target the root Document element in the specific namespace -->
  <xsl:template match="doc:Document">
    <!-- Recreate the element with the default namespace (no prefix) -->
    <Document xmlns="urn:iso:std:iso:20022:tech:xsd:camt.053.001.02">
      <!-- Add the xmlns:xsi namespace attribute -->
      <xsl:attribute name="xmlns:xsi">http://www.w3.org/2001/XMLSchema-instance</xsl:attribute>
      <!-- Add the xsi:schemaLocation attribute with your desired values -->
      <xsl:attribute name="xsi:schemaLocation">urn:iso:std:iso:20022:tech:xsd:camt.053.001.02 camt.053.001.02.xsd</xsl:attribute>
      <!-- Copy all existing attributes from the original element -->
      <xsl:apply-templates select="@*"/>
      <!-- Copy all child nodes from the original element -->
      <xsl:apply-templates select="node()"/>
    </Document>
  </xsl:template>
</xsl:stylesheet>

How This Works #

1. Namespace Binding: We define a doc prefix for the target namespace so we can accurately match the <Document> element (since it lives in that namespace).
2. Identity Template: This handles copying all other nodes and attributes unchanged, so your XML's content stays intact.
3. Root Element Template:
   • We explicitly recreate the <Document> element with the default namespace (no prefix), which removes any ns0 prefix if it existed.
   • We add the xmlns:xsi attribute to declare the XSI namespace.
   • We add the xsi:schemaLocation attribute with your specified schema values.
   • We then copy any existing attributes and child nodes from the original element.

Resulting Output #

When you run this XSLT against your input XML, you'll get exactly the output you want:

<?xml version="1.0" encoding="UTF-8"?>
<Document xmlns="urn:iso:std:iso:20022:tech:xsd:camt.053.001.02"
          xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
          xsi:schemaLocation="urn:iso:std:iso:20022:tech:xsd:camt.053.001.02 camt.053.001.02.xsd">
  <!-- All child nodes from your input will be preserved here -->
</Document>
