以下是我现在用来抓取Bloglines export信息的一个最简陋的php脚本。最前面的两个变量请根据自己的情况进行设置。尤其第一个$cookieVars是需要提交给Bloglines的个性化cookie信息，你可以通过flashget之类的下载工具下载过程中出现的通讯日志得到相关cookie的内容。

<?php
// Supply your cookies information here.
// You can get this from download tools' log such as flashget, etc.
    $cookieVars = "BloglinesLang=0; clickedFoldersubtree=subid13152697%... ... ... BloglinesEmail=..; BloglinesTracker=MXk4...hEVw";

// The filename to save exported opml information.
    $desFileName = "./bloglines_export.xml";

    $hostname = "www.bloglines.com";

    $httpRequest = "";
    $httpRequest .= "GET /export HTTP/1.1\r\n";
    $httpRequest .= "Host: ".$hostname."\r\n";
    $httpRequest .= "Accept: */*\r\n";
    $httpRequest .= "Cookie: ".$cookieVars."\r\n";
    $httpRequest .= "User-Agent: Mozilla/4.0 (compatible; MSIE 5.00; Windows 98)\r\n";
    $httpRequest .= "Pragma: no-cache\r\n";
    $httpRequest .= "Cache-Control: no-cache\r\n";
    $httpRequest .= "Accept: */*\r\n";
    $httpRequest .= "\r\n";

    echo "connecting to the host ".$hostname."<br />";
    flush();

    $resString = "";

    // Open socket to URL
    $sHnd = @fsockopen ($hostname, 80, &$errno, &$errstr, $this->timeout);
    if(!$sHnd){
        $resString = "Connect to host ".$hostname." failed: ".$errstr."[errno=".$errno."]";

由于Bloglines的HTTP Response内容编码采用的chunked格式，所以需要额外的解码处理，你也可以使用更为模块化的CURL或者我这里提供的Advanced HTTP Client Class来发送http Request，效果一样。
