将domeElement转换为字符串,然后删除不需要的标记

dom string xml php

HX_unbanned · 技术社区 · 14 年前

现在,多亏了社区,一个问题解决了( Delete all elements of a certain type from an XML doc using PHP ). 现在我幸运地击中了另一个:)

所以,我有XML文件:

<piletilve_info>
   <shows>
      <show>
        <description>
          <lat>
        <![CDATA[ 
LA CENERENTOLA  <BR><BR>

("Cinderella")<BR><BR>

Opera buffo by Gioachino Rossini<BR><BR>


Music Director and Conductor: Arvo Volmer<BR>
Stage Director and Set Designer: Michiel Dijkema (Amsterdam)<BR>
Costumes: Claudia Damm (Berlin)<BR><BR>



Premiere on November 10, 2006<BR>
Approx running time: 3 h 20 min<BR>
Sung in Italian with subtitles in Estonian and English<BR><BR>

Who hasnât heard the fairy-tale of Cinderella who crouched in the ashes, danced to the tune of her step-sisters but finally found the man of her dreams and a happy life. Why should this fairy-tale be told today?<BR>
An exciting and unexpected solution of the story of Cinderella with striking scenery and fantastic-modern costumes is presented by the Dutch stage director Michiel Dijkema and the German designer Claudia Damm.<BR>
In this story, an unhappy soul dreams of a prince on a white horse and of a better life, and women following the last trends chase the prince, and a man who considers himself very wise, is only interested in himself.<BR>
"Cinderella" is not just a fairy-tale, it includes reality as well as dreams, a lot of fantasies, comedy and grotesque. And all of this is expressed by the brilliant and virtuous music of Rossini!<BR>

  ]]> 
          </lat>
        </description>
      </show>
   </shows>
   <other node>
      ...
   </other node>
</piletilve_info>

我使用以下代码导航到所需的节点:

$books = $xpath->query('shows/show/description');
        foreach($books as $description)
        {
            $description->removeChild($eng_lang);
            $lat_lang = $description->getElementsByTagName('lat')->item(0);
            }

我想输出修改过的 $lat_lang 元素,即 <[[CDATA ]]> 父级,使用此混合函数的内容:

$lat_lang->nodeValue = mb_convert_encoding(print_r(strip_tags_only($lat_lang->item(0)->nodeValue, TRUE),'<html><head><body>'), 'UTF-8' ,$encoding);

,但我失败了,当我在apache服务器上执行脚本时,会出现以下错误:

无法显示XML页无法使用XSL样式查看XML输入工作表。请更正错误并然后单击“刷新”按钮,或尝试稍后再来。

只允许一个顶级元素在XML文档中。错误处理资源 ' http://www.bilesuserviss.lv/lv_filtrs_ ...

可捕捉的致命错误 :对象类DOMElement不能是已转换为/var/www/…中的字符串。。。

你能帮我找到解决办法吗?

也许我在delphi上开发的事实使我编写整个PHP<->XML代码变得比普通人更困难。。:(

是拼写问题。函数名是strip_only_tags(),但我用strip_tags_only()调用它;

我整天都在做delphi和php<gt;xml项目。。已经有点累了:( 对不起大家。

同时也要向戈登汇报。有点把我吵醒了:D
