我希望根据 cusId 按升序排列 customer 标记数据，那么我将如何安排此我尝试使用 xquery 但找不到任何函数关于元素排序，cusId 应该出现在 1,2,3,...

I wish to arrange the customer tag data in ascending order based on cusId so how would i arrange this I tried with xquery but i couldn't find the any function regarding element sorting , cusId should be appear in 1,2,3,...

我将如何实现这一点，我知道 xpath 中没有此功能.

How would i achieve this i know there is no function in xpath for this.

提前致谢.

推荐答案

在 XSLT 中，当使用时，您可以使用 code> 为每个 customer.此样式表对客户进行排序:

In XSLT you can use <xsl:sort> when using <xsl:apply-templates> for each customer. This stylesheet orders the customers:

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform" version="1.0">
    <xsl:output indent="yes"/>
    <xsl:strip-space elements="*"/>

    <xsl:template match="@*|node()">
        <xsl:copy>
            <xsl:apply-templates select="@*|node()"/>
        </xsl:copy>
    </xsl:template>

    <xsl:template match="response">
        <xsl:copy>
            <xsl:apply-templates select="customer-details"/>
            <xsl:apply-templates select="customer">
                <xsl:sort select="cusId"/>
            </xsl:apply-templates>
        </xsl:copy>
    </xsl:template>

</xsl:stylesheet>
