使用Simple Html Dom删除一些元素 - Using Simple Html Dom to remove some elements

这是我试图使用Simple Html-Dom解析的页面。我已经完成了90%的功能，但由于我是图书馆的新手，我不太确定是否能做到这一点。

我想抓取每个新闻项目的文本，但由于文本在<p>元素内，使用类似->innertext的东西可以将所有内容都包含在内，包括链接。

以下是我尝试过的：

<h1>Scraper Noticias</h1>
<?php
include('simple_html_dom.php');
class News {
    var $image;
    var $fechanoticia;
    var $title;
    var $description;
    var $sourceurl;
    function get_image( ) {
        return $this->image;
    }
    function set_image ($new_image) {
        $this->image = $new_image;
    }
    function get_fechanoticia( ) {
        return $this->fechanoticia;
    }
    function set_fechanoticia ($new_fechanoticia) {
        $this->fechanoticia = $new_fechanoticia;
    }
    function get_title( ) {
        return $this->title;
    }
    function set_title ($new_title) {
        $this->title = $new_title;
    }
    function get_description( ) {
        return $this->description;
    }
    function set_description ($new_description) {
        $this->description = $new_description;
    }
    function get_sourceurl( ) {
        return $this->sourceurl;
    }
    function set_sourceurl ($new_sourceurl) {
        $this->sourceurl = $new_sourceurl;
    }
}
// Create DOM from URL or file
$html = file_get_html('http://www.uvm.cl/noticias_mas.shtml');
$parsedNews = array();
// Find all news items.
foreach($html->find('#cont2 p') as $element) {
    $newItem = new News;
    // Parse the news item's thumbnail image.
    foreach ($element->find('img') as $image) {
        $newItem->set_image($image->src);
        //echo $newItem->get_image() . "<br />";
    }
    // Parse the news item's post date.
    foreach ($element->find('span.fechanoticia') as $fecha) {
        $newItem->set_fechanoticia($fecha->innertext);
        //echo $newItem->get_fechanoticia() . "<br />";
    }
    // Parse the news item's title.
    foreach ($element->find('a') as $title) {
        $newItem->set_title($title->innertext);
        //echo $newItem->get_title() . "<br />";
    }
    // Parse the news item's source URL link.
    foreach ($element->find('a') as $sourceurl) {
        $newItem->set_sourceurl("http://www.uvm.cl/" . $sourceurl->href);
    }
    // Parse the news items' description text.
    echo $link; //This is the entire <p> tag. How can I get just the text. Not the link?
} 
?>

这是我找到的一个解决方案。尽管如果我能改进代码，我将不胜感激。

<h1>Scraper Noticias</h1>
<?php
include('simple_html_dom.php');
class News {
    var $image;
    var $fechanoticia;
    var $title;
    var $description;
    var $sourceurl;
    function get_image( ) {
        return $this->image;
    }
    function set_image ($new_image) {
        $this->image = $new_image;
    }
    function get_fechanoticia( ) {
        return $this->fechanoticia;
    }
    function set_fechanoticia ($new_fechanoticia) {
        $this->fechanoticia = $new_fechanoticia;
    }
    function get_title( ) {
        return $this->title;
    }
    function set_title ($new_title) {
        $this->title = $new_title;
    }
    function get_description( ) {
        return $this->description;
    }
    function set_description ($new_description) {
        $this->description = $new_description;
    }
    function get_sourceurl( ) {
        return $this->sourceurl;
    }
    function set_sourceurl ($new_sourceurl) {
        $this->sourceurl = $new_sourceurl;
    }
}
// Create DOM from URL or file
$html = file_get_html('http://www.uvm.cl/noticias_mas.shtml');
$parsedNews = array();
// Find all news items.
foreach($html->find('#cont2 p') as $element) {
    $newItem = new News;
    // Parse the news item's thumbnail image.
    foreach ($element->find('img') as $image) {
        $newItem->set_image($image->src);
        //echo $newItem->get_image() . "<br />";
    }
    // Parse the news item's post date.
    foreach ($element->find('span.fechanoticia') as $fecha) {
        $newItem->set_fechanoticia($fecha->innertext);
        //echo $newItem->get_fechanoticia() . "<br />";
    }
    // Parse the news item's title.
    foreach ($element->find('a') as $title) {
        $newItem->set_title($title->innertext);
        //echo $newItem->get_title() . "<br />";
    }
    // Parse the news item's source URL link.
    foreach ($element->find('a') as $sourceurl) {
        $newItem->set_sourceurl("http://www.uvm.cl/" . $sourceurl->href);
    }
    // Parse the news items' description text.
    foreach ($element->find('a') as $link) {
        $link->outertext = '';
    }
    foreach ($element->find('span') as $link) {
        $link->outertext = '';
    }
    foreach ($element->find('img') as $link) {
        $link->outertext = '';
    }
    echo $element->innertext;
} 
?>

使用innertext而不是outertext

    foreach ($element->find('a') as $sourceurl) {
    echo $sourceurl->innertext . "<br />";
    }
