如何使用xslt在没有硬编码的情况下从另一个xml生成xml属性值

标签： xml xslt xslt-1.0 xslt-2.0

我看到了一个使用JSTL将xml转换为另一个xml的示例。但在该示例中，他们对属性值进行了硬编码。请参阅下面的例子

输入XML

在这个输出xml中我创建了许多RECORD子元素。我的问题是我想在没有硬编码的情况下转换PROB名称属性（ ）值。我需要从输入xml读取 reagion 元素，并将该值转换为输出xml。请帮我找到解决方案。
谢谢......

我相信这就是你要找的东西：

<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform">

  <xsl:template match="/">
    <xsl:apply-templates select="/country/regions" />
  </xsl:template>

  <xsl:template match="regions">
    <RECORDS>
      <xsl:apply-templates select="region" />
    </RECORDS>
  </xsl:template>

  <xsl:template match="region">
    <RECORD>
      <xsl:apply-templates select="@*" />
    </RECORD>
  </xsl:template>

  <xsl:template match="region/@*">
    <PROP name="{name()}">
      <PVAL>
        <xsl:value-of select="." />
      </PVAL>
    </PROP>
  </xsl:template>
</xsl:stylesheet>

在输入XML上运行时，会产生输出：

<RECORDS>
  <RECORD>
    <PROP name="isocode">
      <PVAL>DE-BW</PVAL>
    </PROP>
    <PROP name="pk">
      <PVAL>8796093055011</PVAL>
    </PROP>
    <PROP name="uri">
      <PVAL>http://localhost:9001/ws410/rest/countries/de/regions/DE-BW</PVAL>
    </PROP>
  </RECORD>
  <RECORD>
    <PROP name="isocode">
      <PVAL>DE-BY</PVAL>
    </PROP>
    <PROP name="pk">
      <PVAL>8796093087779</PVAL>
    </PROP>
    <PROP name="uri">
      <PVAL>http://localhost:9001/ws410/rest/countries/de/regions/DE-BY</PVAL>
