xml - XSL : for-each select a string with umlauts

Question

我有以下 XML:

<FeatureGroup FeatureGroup="Bundesländer">
    <Feature>
        <FeatureValue>
            <Value LanguageCode="fr">Brandenburg</Value>
            <Value LanguageCode="de">Brandenburg</Value>
            <Value LanguageCode="en">Brandenburg</Value>
        </FeatureValue>
    </Feature>
</FeatureGroup>

我希望它由 xsl 转换，但我无法选择 FeatureGroup-Value“Bundesländer”。这是 xsl:

<field name="federalState">
    <xsl:for-each select="FeatureGroups/FeatureGroup[FeatureGroup = 'Bundesländer']">
        <xsl:for-each select="Feature/FeatureValue/Value[@LanguageCode= 'de']">
            <xsl:value-of select="." />
        </xsl:for-each>
    </xsl:for-each>
</field>

我如何选择一个带有变音符号的属性值？

Answer 1

XML 和 XPath 完全支持 Unicode，因此选择任何 Unicode 字符都不是问题，您只需要确保您的路径选择带有 @ 的属性节点即可。即替换 <xsl:for-each select="FeatureGroups/FeatureGroup[FeatureGroup = 'Bundesländer']">通过 <xsl:for-each select="FeatureGroups/FeatureGroup[@FeatureGroup = 'Bundesländer']"> .
