xml - 匹配特定父节点XSLT的特定子属性

Question

我正在尝试使用XSL在以下XML中匹配并更改方面名称x的displayHeight属性的值，但是以下XSL模板更改了所有displayHeight值。我需要以下模板来匹配仅纵横比名称为x的displayHeight属性。

<xsl:template match="@value[parent::property[@name='displayHeight']]">
    <xsl:attribute name="value">
        <xsl:value-of select="'Value Has Been Changed By XSL'"/>
    </xsl:attribute>
</xsl:template>

XML来源

<?xml version="1.0" encoding="utf-8"?>
<a>
    <b>
        <aspect name="x">
           <properties>
                 <property name="displayHeight" value="600"/>
                 <property name="displayWidth" value="800"/>
            </properties>
         </aspect>
         <aspect name="y">
             <properties>
                    <property name="displayHeight" value="1280"/>
                    <property name="displayWidth" value="720"/>
                </properties>
         </aspect>
    </b>
</a>

用

<xsl:template match="aspect[@name = 'x']/properties/property[@name = 'displayHeight']/@value">
    <xsl:attribute name="value">
        <xsl:value-of select="'Value Has Been Changed By XSL'"/>
    </xsl:attribute>
</xsl:template>
