Question

If there are other classes written to do this, a link would be awesome. If not, how can I do it with PHPCrawl?

是否有可能根据该场址的一套具体规则,从一个无计划场址储存具体信息? Ex., [div.want this, img#defaultPicture]?

在PHPC的拖网中,我如何能够从<代码>$_data阵列中获取这一信息?

只能针对某些因素。

不妨将数据储存规则从一个变量(可以是一阵列,具体列明指标)。

你们要求的是,如何利用PHPC的扩展将A站点的具体内容和B站点的其他具体内容混为一谈。

可在以下网址上填写:

for url in urls:
    content = crawl(url)
    if(url of type 1?):
        extract_style1(content)
    else-if(url of type 2?):
        extract_style2(content)
    else:
        extract_styledefault(content)

For specific content extracting following algo can be used:

Note: There are spectrum of parsing techniques avaliable, I am implmeneting HTML DOM Parsing here..

// Create DOM from your PHP Crawl Data Source
$html = $page_data[source]

// Find all images 
foreach($html->find( img ) as $element) 
       echo $element->src .  <br> ;

// Find all links 
foreach($html->find( a ) as $element) 
       echo $element->href .  <br> ;
