我正在尝试基于文本进行排序 - XSLT [英] I am trying to sorting based on Text - XSLT

问题描述

我正在尝试对基于文本的文本进行排序，第一个文本应为大写，然后其他以首字母大写或小写字母开头.
输入 XML

I am trying to sorting on text based first text should be upper case then other start with first letter caps or small letter.
Input XML

    <?xml version="1.0" encoding="UTF-8"?>
    <root>
        <p content-type="emCase"><named-content content-type="emEntry">B</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">BTS, USA, Inc. v Executive Perspectives, LLC (Conn. Super, Oct. 16, 2014, No. X10CV116010685) 2014 Conn Super Lexis 2644, aff’d (Conn App 2016) 142 A3d 342:</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">buySAFE, Inc. v Google, Inc. (Fed Cir 2014) 765 F3d 1350:</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">Babcock v Butler County (3d Cir 2015) 806 F3d 153:</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">Buxbom v Smith (1944) 23 C2d 535:</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">Byrd v Roadway Express, Inc. (5th Cir 1982) 687 F2d 85:</named-content></p>
        <p content-type="emCase"><named-content content-type="emEntry">B.K.B. v Maui Police Dep’t (9th Cir 2002) 276 F3d 1091:</named-content></p>
    </root>

    </root>

我的 XSLT 代码

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

<xsl:template match="root">
    <xsl:copy>
        <xsl:for-each select="p[named-content[@content-type='emEntry'][matches(., '^([A-Za-z]+)')]]">
            <xsl:sort select="if(named-content[@content-type='emEntry' and matches(., '^([A-Z]+)')]) then named-content[@content-type='emEntry' and matches(., '^([A-Z]+)')] else upper-case(named-content[@content-type='emEntry'])" data-type="text" order="ascending"/>
            <xsl:text>&#x0A;</xsl:text>
            <xsl:copy>
                <xsl:apply-templates select="@*|node()"/>
            </xsl:copy>
        </xsl:for-each>
    </xsl:copy>
</xsl:template>

谁能帮我看看我的错误代码在哪里?

Can any one help me that where is my wrong code?

推荐答案

以下是否符合您的要求?(需求很难理解.我假设有更简单、更快的 XSLT 代码来完成这个任务......)

Does the following meet your requirements? (Requirements were hard to understand. I assume there is more simple and faster XSLT code to accomplish this task ...)
