獲取XML元素文本，跳過某些元素，轉換為單個字符串

Question

給定此源文件（file.xml）：

<article>
<story name="column">
    <runs>
        <run p="902" c="103">
            THINK ABOUT IT
        </run>
    </runs>
</story>
<story name="body">
    <runs>
        <run p="895" c="103">
            ‘
        </run>
        <run p="895" c="920">
            T
        </run>
        <run p="895" c="103">
            here is an abiding
            <eol />
            beauty which may be
            <eol />
            appreciated by those
            <eol />
            who will see things as
            <eol />
            they are and who will
            <eol />
            ask for no reward
            <eol />
            except to see.’
            <eol />
        </run>
        <run p="896" c="103">
            Vera Brittain
            <eol />
            (1893-1970)
            <eol />
        </run>
        <run p="897" c="103">
            British author
        </run>
    </runs>
</story>

我把它拉成了一個簡單的PHP腳本，以獲取具有屬性'body'的story元素中的所有文本：

<?php

$xml = simplexml_load_file( "file.xml" );

$body = $xml->xpath( "//story[@name='body']/*[not(self::eol)]" );
if( $body ){
    print_r( $body[0] );
}

?>

我的輸出幾乎是我的預期：

SimpleXMLElement Object
(
    [run] => Array
        (
            [0] => ‘
            [1] => T
            [2] => here is an abiding beauty which may be appreciated by those who will see things as they are and who will ask for no reward except to see.’
    
            [3] => Vera Brittain 
    (1893-1970)
    
            [4] => British author
        )
)

無論出於何種原因，我找不到一種方法來訪問這些值以將它們連接在一起。 我試過通過$body[0] ， $body[0]->run等解析，但沒有什么能給我我期望的結果。

最重要的是，我需要獲得一個值為的字符串：

‘There is an abiding 
beauty which may be 
appreciated by those 
who will see things as 
they are and who will 
ask for no reward 
except to see.’

如果您能夠從代碼中運行XSLT 1.0樣式表，這里有一些XSLT代碼可以為您提供結果：

<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet xmlns:xsl="http://www.w3.org/1999/XSL/Transform"
    version="1.0">
    <xsl:output method="text"/>
    <xsl:strip-space elements="*"/>
    <xsl:template match="/">
        <xsl:apply-templates select="//story[@name='body']"/>
    </xsl:template>
    <xsl:template match="text()">
        <xsl:value-of select="normalize-space(.)"/>
    </xsl:template>
    <xsl:template match="eol">
        <xsl:text>&#13;</xsl:text>
    </xsl:template>
</xsl:stylesheet>

對於此輸入：

<?xml version="1.0" encoding="UTF-8"?>
<article>
    <story name="column">
        <runs>
            <run p="902" c="103">
                THINK ABOUT IT
            </run>
        </runs>
    </story>
    <story name="body">
        <runs>
            <run p="895" c="103">
                ‘
            </run>
            <run p="895" c="920">
                T
            </run>
            <run p="895" c="103">
                here is an abiding
                <eol />
                beauty which may be
                <eol />
                appreciated by those
                <eol />
                who will see things as
                <eol />
                they are and who will
                <eol />
                ask for no reward
                <eol />
                except to see.’
                <eol />
            </run>
            <run p="896" c="103">
                Vera Brittain
                <eol />
                (1893-1970)
                <eol />
            </run>
            <run p="897" c="103">
                British author
            </run>
        </runs>
    </story>
</article>

結果是：

‘There is an abiding
beauty which may be
appreciated by those
who will see things as
they are and who will
ask for no reward
except to see.’
