【问题描述】:
我有这个 php sn-p:
$xsltPath = $argv[1];
$xmlPath = $argv[2];
$xslt = file_get_contents($xsltPath);
$xml = file_get_contents($xmlPath);
$templateCMSObj = new \DOMDocument();
$templateCMSObj->loadXML($xslt);
$ekbXMLObj = new \DOMDocument();
$ekbXMLObj->loadXML($xml);
$proc = new \XSLTProcessor();
$proc->importStylesheet($templateCMSObj);
$html = $proc->transformToXML($ekbXMLObj);
echo($html);
exit;
这只是将 XSLT 应用于给定的 XML 文档。
当我将以下 XSLT 应用到同一个 XML 文档时,我得到了 Windows wrt 与 Linux PHP 版本不同的行为。
这里是 php 和 libxml 版本详情:
Windows:

这是 XSLT 代码:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns="http://new.webservice.namespace">

<xsl:variable name="closed_bracket" select="'}'"/>
<xsl:template match="/">
<ns:flat_pallet>
<xsl:attribute name="tipo"><xsl:value-of select="//ns:EKB_piatto/@tipo"/></xsl:attribute>
<xsl:apply-templates select=".//ns:gruppo_logico/ns:versione/ns:contenuto/ns:riferimento_oi"/>
</ns:flat_pallet>
</xsl:template>
<!--restituisco tipo del box e l'indice relativo a nel sottoalbero-->
<xsl:template match="ns:gruppo_logico">

<xsl:value-of select="$closed_bracket"/>
<xsl:value-of select="$slash"/>
</xsl:template>
<!--quando sono in una unit risalgo i box progenitori-->
<xsl:template match="ns:riferimento_oi">

</xsl:variable>
<xsl:copy>

<xsl:attribute name="unitIndex"><xsl:value-of select="$index" disable-output-escaping="yes"/></xsl:attribute>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<xsl:template match="@*|node()">
<!-- just copy all my attributes and child nodes, except if there's a better template for some of them -->
<xsl:copy>
<xsl:apply-templates select="@*|node()"/>
</xsl:copy>
</xsl:template>
<!--template per rimuovere nodi vuoti-->
<xsl:template match="*[not(@*|*|comment()|processing-instruction()) and normalize-space()='']"/>
</xsl:stylesheet>
以及在 win 和 linux 中给出不同结果的 XML Doc XSLT:
<?xml version="1.0" encoding="UTF-8" standalone="yes"?>
<ns:dettaglioFormEKBSOUT xmlns:ns="http://new.webservice.namespace">
<ns:EKB_piatto>
<ns:campo_GL>

<ns:versione id="1">
<ns:contenuto>
<ns:riferimento_oi>

<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:contenuto>
<ns:contenuto>
<ns:riferimento_oi>
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:contenuto>
</ns:versione>
</ns:gruppo_logico>
<ns:gruppo_logico tipo="Standard_due">
<ns:versione id="1">
<ns:contenuto>
<ns:riferimento_oi>
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:contenuto>

</ns:contenuto>
</ns:versione>
</ns:gruppo_logico>
</ns:campo_GL>
</ns:EKB_piatto>
</ns:dettaglioFormEKBSOUT>
Linux 输出 这是在 Linux 上应用 XSLT 实际产生的所需输出:
<?xml version="1.0"?>
<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">
<ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{0}/Standard_due{0}" unitIndex="1">
<ns:tipo>Standard_due</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:flat_pallet>
Windows 输出 这是在 Windows 上产生的错误结果:
<?xml version="1.0"?>
<ns:flat_pallet xmlns:ns="http://new.webservice.namespace" tipo="">
<ns:riferimento_oi labelPath="Standard{0}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard{0}/Standard{1}" unitIndex="2">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{NaN}/Standard{0}" unitIndex="1">
<ns:tipo>Standard</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.1</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
<ns:riferimento_oi labelPath="Standard_due{NaN}/Standard_due{NaN}" unitIndex="">
<ns:tipo>Standard_due</ns:tipo>
<ns:natura_OI>
<ns:UNI>2.2</ns:UNI>
</ns:natura_OI>
</ns:riferimento_oi>
</ns:flat_pallet>
问题在于 NaN put 而不是相对索引:它肯定与 xsl:number 元素有关,但我不知道如何解决这个问题...
接受答案后编辑
通过将xsl:number count 属性更改为* 而不是node(),xslt 模板在 Win 和 Linux 上都可以正常工作。
这是更新后的代码:
<?xml version="1.0" encoding="UTF-8"?>
<xsl:stylesheet version="1.0" xmlns:xsl="http://www.w3.org/1999/XSL/Transform" xmlns:ns="http://new.webservice.namespace">

<xsl:variable name="dot" select="'.'"/>
<xsl:variable name="open_bracket" select="'{'"/>
<xsl:variable name="closed_bracket" select="'}'"/>
<xsl:template match="/">
<ns:flat_pallet>
<xsl:attribute name="tipo"><xsl:value-of select="//ns:EKB_piatto/@tipo"/></xsl:attribute>
<xsl:apply-templates select=".//ns:gruppo_logico/ns:versione/ns:contenuto/ns:riferimento_oi"/>
</ns:flat_pallet>
</xsl:template>
<!--restituisco tipo del box e l'indice relativo a nel sottoalbero-->

</xsl:template>

【问题讨论】:
-
我发现 Linux 和 Windows 的输出没有区别。
-
这很有趣!问题甚至可以在xslt fiddle 中重现,将 Saxon 和其他人之间的引擎切换到“客户端处理器”。
-
如果示例被最小化为仅显示问题所必需的内容,这将更容易(并且对其他人更有用) - 请参阅:minimal reproducible example。
-
在xsltfiddle.liberty-development.net/6qVRKxe/2,我尝试使用 Chrome(至少我在 Windows 10 64 位上的当前版本 70.0.3538.102)制作一个简化的测试用例,它显示了问题。 @nwellnhof,这是 Windows 版本的 libxslt 中的错误吗?我很难为 Windows 找到最新的 xsltproc/libxslt 二进制文件来测试自己。
-
为了它的价值,我在 Windows 上尝试了最新的 PHP 版本 7.2.12,它具有最新的 libxslt 1.1.32 并且它显示了问题,所以我在 gitlab.gnome.org/GNOME/libxslt/issues/6 上打开了一个关于 libxslt 的问题看看他们是否认为这是一个错误。
