如何使用simpleXML为xml节点执行字符串替换？

I was wondering if you could help. The code below pulls in XML data from an external XML file and then re-formats it into table data. All works perfect. However, some of the data from the XML file needs to be changed and so is it possible to use str_replace or preg_replace for each individual node below? I do not know how to write the str_replace for each node. I thought perhaps something like this "{$hour->weatherCod} . str_replace (10, Sun);" would work but it doesn't. Would smeone be able to tell me the correct format? I need something easy as I am more of an actionscript guy rather than php.

我想知道你是否可以提供帮助。下面的代码从外部XML文件中提取XML数据,然后将其重新格式化为表数据。一切都很完美。但是,需要更改XML文件中的某些数据,因此可以为下面的每个单独节点使用str_replace或preg_replace吗?我不知道如何为每个节点编写str_replace。我想也许是这样的“{$ hour-> weatherCod} .str_replace(10,Sun);”会工作,但事实并非如此。请问我能告诉我正确的格式吗?我需要一些简单的东西,因为我更像是一个动作脚本而不是php。

Many thanks if youre able to help!

非常感谢你能提供帮助!

<?php
// load SimpleXML
$data = new SimpleXMLElement('xml_file.xml', null, true);
foreach($data->weather as $weather)
{
foreach ($weather->hourly as $hour)
{
echo <<<EOF
    <tr>
            <td>{$weather->day}</td>
            <td>{$weather->Ctemp1}&deg;c</td>
            <td>{$weather->Ctemp2}&deg;c</td>
            <td>{$hour->time}</td>
            <td>{$hour->tempC}&deg;c</td>
            <td>{$hour->tempF}&deg;f</td>

            <td>{$hour->waterTemp_C}&deg;c</td>
            <td>{$hour->waterTemp_F}&deg;f</td>
    </tr>
EOF;
}
}
echo '</table>';
?>

Actually what you try to do with {$hour->weatherCod} . str_replace (10, Sun); ?

实际上你尝试用{$ hour-> weatherCod}做什么。 str_replace(10,Sun); ?

Look how it works, it takes 3 parameters not 2. http://php.net/manual/en/function.str-replace.php

看它是如何工作的,它需要3个参数而不是2. http://php.net/manual/en/function.str-replace.php

So may by something like this

可能是这样的事情

str_replace (10, Sun, $hour->weatherCod);
