如何在 PHP 5 中启用 XSLT 功能？

发布于 2024-10-08 02:31:07 字数 1104 浏览 8 评论 0原文

我想使用 xslt 将 xml 文件打印为 HTML 嵌套列表，据我所知代码是正确的，但是我收到此错误

致命错误：调用未定义的函数 xslt_create()

我认为这意味着 xslt 函数尚未启用。如何在 PHP 中启用这些功能？是否有我需要包含的 php 文件（就像 Javascript 库的工作方式）还是更复杂的文件？我由 MediaTemple 托管。

这是我正在使用的 php 代码：

        <?php 

    // Allocate a new XSLT processor 
    $xh = xslt_create(); 

    // Process the document, returning the result into the $result variable 
    $result = xslt_process($xh, 'armstrong.xml', 'familyToNestedList.xsl'); 
    if ($result) { 
        print "SUCCESS, sample.xml was transformed by sample.xsl into the \$result"; 
        print " variable, the \$result variable has the following contents\n<br>\n"; 
        print "<pre>\n"; 
        print $result; 
        print "</pre>\n"; 
    } 
    else { 
        print "Sorry, sample.xml could not be transformed by sample.xsl into"; 
        print "  the \$result variable the reason is that " . xslt_error($xh) .  
        print " and the error code is " . xslt_errno($xh); 
    } 

    xslt_free($xh); 

    ?>

提前致谢！

I'm wanting to print an xml file out as an HTML nested list using xslt, and as far as I know the code is correct, however I'm getting this error

Fatal error: Call to undefined function xslt_create()

Which I presume means the xslt functions havn't been enabled. How do I enable these functions within PHP? Is there a php file I need to include (like the way Javascript libraries work) or is it something more complicated? I'm hosted with MediaTemple.

Here's the php code I'm using:

        <?php 

    // Allocate a new XSLT processor 
    $xh = xslt_create(); 

    // Process the document, returning the result into the $result variable 
    $result = xslt_process($xh, 'armstrong.xml', 'familyToNestedList.xsl'); 
    if ($result) { 
        print "SUCCESS, sample.xml was transformed by sample.xsl into the \$result"; 
        print " variable, the \$result variable has the following contents\n<br>\n"; 
        print "<pre>\n"; 
        print $result; 
        print "</pre>\n"; 
    } 
    else { 
        print "Sorry, sample.xml could not be transformed by sample.xsl into"; 
        print "  the \$result variable the reason is that " . xslt_error($xh) .  
        print " and the error code is " . xslt_errno($xh); 
    } 

    xslt_free($xh); 

    ?>

Thanks in advance!

根据您的 Linux 发行版，您可能只需安装 php5-xsl 模块，将“extension=php_xsl.so”行添加到 php.ini 文件中，然后重新启动 apache2 服务器即可。

这在 Ubuntu 11.10 上对我有用。您可以在命令行中输入“sudo apt-get install php5-xsl”来安装php5-xml。

您必须编译 PHP 并支持它，并确保拥有所有所需的依赖项。请参阅XSLT PHP 手册中的相应章节。

来自章节要求

此扩展需要 libxml PHP 扩展。这意味着还需要传入 --enable-libxml，尽管这是隐式完成的，因为默认情况下启用了 libxml。此扩展使用 Sablotron 和 expat，两者均可在 » http://freshmeat.net/projects/sablotron 找到/。提供了二进制文件以及源代码。通过使用 PHP 4 的 --with-xslt 选项来启用。

来自章节安装

在 Unix 上，使用 --enable-xslt --with-xslt-sablot 选项运行 configure。 Sablotron 库应该安装在编译器可以找到的地方。确保链接到 Sablotron 库的库与与 PHP 链接的库相同。配置选项： --with-expat-dir=DIR --with-iconv-dir=DIR 可帮助您指定它们。在寻求支持时，请务必提及这些指令，以及您的系统上是否安装了这些库的其他版本。当然，请提供所有版本号。

在 PHP5 中使用 XSL 转换的推荐扩展是 XSL。如果您需要做的只是转换两个文档（如示例所示），请考虑 PHP 手册中的示例：

$xml = new DOMDocument;
$xml->load('collection.xml');

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

// Configure the transformer
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl); // attach the xsl rules

echo $proc->transformToXML($xml);

transformToXML 方法将返回转换后的文档或 FALSE，所以你可以在代码中保留 if/else 。无论如何，升级代码应该很简单。

You have to compile PHP with the support for it and make sure to have all the required dependencies. Please see the corresponding chapters in the PHP Manual for XSLT.

From chapter Requirements

This extension requires the libxml PHP extension. This means that passing in --enable-libxml is also required, although this is implicitly accomplished because libxml is enabled by default. This extension uses Sablotron and expat, which can both be found at » http://freshmeat.net/projects/sablotron/. Binaries are provided as well as source. Enable by using the --with-xslt option with PHP 4.

From chapter Installation

On Unix, run configure with the --enable-xslt --with-xslt-sablot options. The Sablotron library should be installed somewhere your compiler can find it. Make sure you have the same libraries linked to the Sablotron library as those, which are linked with PHP. The configuration options: --with-expat-dir=DIR --with-iconv-dir=DIR are there to help you specify them. When asking for support, always mention these directives, and whether there are other versions of those libraries installed on your system somewhere. Naturally, provide all the version numbers.

The recommended extension for using XSL transformations with PHP5 is XSL. If all you need to do is transform two documents, as show in your example, consider this example from the PHP Manual:

$xml = new DOMDocument;
$xml->load('collection.xml');

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

// Configure the transformer
$proc = new XSLTProcessor;
$proc->importStyleSheet($xsl); // attach the xsl rules

echo $proc->transformToXML($xml);

The transformToXML method will return the transformed document or FALSE, so you can keep the if/else from your code. In any case, it should be trivial to upgrade your code.
