使用xslt重新格式化xml文件並保留確切格式

Question

我有一個xml文件需要以特定方式格式化以確保可讀性。

源XML

<?xml version="1.0" encoding="UTF-8"?> 
<facility> 
<attributes> 
    <id>1</id> 
    <name>Facility Name</name> 
    <coordinate>Lat,Long</coordinate> 
    <projection>mercator</projection> 
    <units>imperial</units> 
    <showcart>yes</showcart> 
    <shotplanner>yes</shotplanner> 
    <sound>on</sound> 
    <gfbkgcolor>#ff0000</gfbkgcolor> 
    <gftxtcolor>#ffffff</gftxtcolor> 
    <gcbkgcolor>#ffffff</gcbkgcolor> 
    <gctxtcolor>#000000</gctxtcolor> 
</attributes> 
</facility> 

期望輸出

<facility name="Facility Name" id="1" 
      coordinate="Lat,Long" projection="mercator" 
      units="imperial" showcart="yes" shotplanner="yes" 
      sound="on" gfbkgcolor="#ff0000" gftxtcolor="#ffffff" 
      gcbkgcolor="#ffffff"> 
</facility> 

Ive得到了一個複雜的XML文件，但是那幾乎是我想要做的事。

XSL模板

<?xml version="1.0" encoding="UTF-8"?> 
<xsl:stylesheet version="1.0" 
xmlns:xsl="http://www.w3.org/1999/XSL/Transform"> 
<xsl:output method="xml" indent="yes"/> 
<xsl:template match="/"> 
    <xsl:for-each select="facility/attributes"> 
     <facility id="{id}" name="{name}" 
        coordinate="{coordinate}"> 
     </facility> 
     <xsl:text>&#xA;</xsl:text> 
     <test>"hello"</test> 
    </xsl:for-each> 
</xsl:template> 
</xsl:stylesheet> 

使用此<xsl:text>&#xA;</xsl:text>似乎拋出一個錯誤，並且不顯示輸出XML。

1. 是否有可能在使用xsl的某些屬性之後出現換行符？
2. 我可以在給定元素中的兒童之間有換行符（所以他們可以按邏輯分組）？

我正在通過php形成上述xml。一旦我有了這個xml，我希望它能像上面提到的那樣格式化。我可以使用PHP字符串來完成它，但它是一個巨大的文件，並且這樣做會非常繁瑣。 xsl可以用來解決這個問題嗎？

任何關於如何實現這一點的指針將不勝感激。 Thx

Answer 1

我不知道任何XML序列化程序（基於XSLT或其他），可以讓您控制一組屬性的格式，儘管您可能會利用saxon：xsl：output上的屬性順序和saxon：行長屬性：請參閱http://www.saxonica.com/documentation/index.html#!extensions/output-extras/serialization-parameters。

目前尚不清楚爲什麼您當前的代碼會拋出錯誤，但由於您沒有告訴我們錯誤是什麼，因此我不會回答問題的這一部分。

作爲PHP是一種通用語言，並配備了XSLT 1。0處理器，你可以在一個腳本處理這兩種操作，XML轉換和文本格式，：

XSLT腳本（保存在外部被加載低於或添加爲loadXML的嵌入式字符串（））

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

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

    <!-- Migrate Nodes to Attributes --> 
    <xsl:template match="attributes/*">  
     <xsl:attribute name="{name()}"> 
     <xsl:value-of select="."/> 
     </xsl:attribute> 
    </xsl:template> 

</xsl:transform> 

PHP腳本

<?php 

// Load the XML source and XSLT file 
$doc = new DOMDocument(); 
$doc->load('Source.xml'); 

$xsl = new DOMDocument; 
$xsl->load('XSLTScript.xsl'); 

// Configure the processor 
$proc = new XSLTProcessor; 
$proc->importStyleSheet($xsl); 

// Transform XML source 
$newXml = $proc->transformToXML($doc); 

// Add line breaks, tabs, and spaces between attributes to output string 
$newXml = str_replace("coordinate", "\n\t\t coordinate", $newXml); 
$newXml = str_replace("units", "\n\t\t units", $newXml); 
$newXml = str_replace("sound", "\n\t\t sound", $newXml); 
$newXml = str_replace("gcbkgcolor", "\n\t\t gcbkgcolor", $newXml); 
$newXml = str_replace("/>", ">\n</facility>", $newXml); 

echo $newXml; 

// Save output to file 
$xmlfile = 'Output.xml'; 
file_put_contents($xmlfile, $newXml); 

?> 

輸出

<?xml version="1.0" encoding="UTF-8"?> 
<facility id="1" name="Facility Name" 
      coordinate="Lat,Long" projection="mercator" 
      units="imperial" showcart="yes" shotplanner="yes" 
      sound="on" gfbkgcolor="#ff0000" gftxtcolor="#ffffff" 
      gcbkgcolor="#ffffff" gctxtcolor="#000000"> 
</facility>
