基于XPath值在XSLT中动态生成字符串的解决方案求助

Got it, here's a clean, straightforward XSLT solution tailored to your requirement. It checks each of your XPath conditions and builds the concatenated string only for those that evaluate to 'Y':

XSLT 2.0+ Version (Recommended for Simplicity) #

This version leverages sequences and the string-join function, which makes the logic concise and easy to maintain:

<xsl:stylesheet version="2.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:us="your-us-namespace-uri" xmlns:ws="your-ws-namespace-uri">

  <xsl:template match="/">
    <!-- Collect roles where the corresponding condition is 'Y' into a sequence -->
    <xsl:variable name="roles" as="xs:string*">
      <xsl:if test="us:user/ws:Additional_Information/ws:is_HR = 'Y'">HR</xsl:if>
      <xsl:if test="us:user/ws:Additional_Information/ws:is_Manager = 'Y'">Manager</xsl:if>
      <xsl:if test="us:user/ws:Additional_Information/ws:is_Employee = 'Y'">Employee</xsl:if>
      <xsl:if test="us:user/ws:Additional_Information/ws:is_Admin = 'Y'">Admin</xsl:if>
    </xsl:variable>

    <!-- Join the sequence with hyphens to form the final string -->
    <xsl:value-of select="string-join($roles, '-')"/>
  </xsl:template>

</xsl:stylesheet>

How it works:

• Each <xsl:if> checks if the corresponding XPath returns 'Y' — if yes, it adds the matching role name to a sequence.
• string-join then combines all elements in the sequence with hyphens. If all conditions are met, it outputs HR-Manager-Employee-Admin; if only, say, is_HR and is_Admin are 'Y', it outputs HR-Admin.

XSLT 1.0 Version (For Legacy Environments) #

If you're stuck with XSLT 1.0 (which lacks sequences and string-join), here's a compatible alternative:

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
                xmlns:us="your-us-namespace-uri" xmlns:ws="your-ws-namespace-uri">

  <xsl:template match="/">
    <!-- Store each condition result as a boolean variable -->
    <xsl:variable name="is-hr" select="us:user/ws:Additional_Information/ws:is_HR = 'Y'"/>
    <xsl:variable name="is-manager" select="us:user/ws:Additional_Information/ws:is_Manager = 'Y'"/>
    <xsl:variable name="is-employee" select="us:user/ws:Additional_Information/ws:is_Employee = 'Y'"/>
    <xsl:variable name="is-admin" select="us:user/ws:Additional_Information/ws:is_Admin = 'Y'"/>

    <!-- Build a string with hyphen-prefixed roles -->
    <xsl:variable name="raw-role-string">
      <xsl:if test="$is-hr">-HR</xsl:if>
      <xsl:if test="$is-manager">-Manager</xsl:if>
      <xsl:if test="$is-employee">-Employee</xsl:if>
      <xsl:if test="$is-admin">-Admin</xsl:if>
    </xsl:variable>

    <!-- Remove the leading hyphen (if any) to get the final result -->
    <xsl:value-of select="substring($raw-role-string, 2)"/>
  </xsl:template>

</xsl:stylesheet>

Note:

Don't forget to replace your-us-namespace-uri and your-ws-namespace-uri with the actual namespace URIs used in your XML input.
