最近發現有時候抓回來的RSS，會有格式錯誤的問題，
問了我們這的大師 部落小波 後，他指引了我一條路 【HTML Tidy Library Project】
( 真的覺的 部落小波 懂的還真多耶~~ )
Tidy 這東西可以把一些缺少的或多餘的Tag修正，
因為現在很多發表文章的編輯器，都可以自己修改程式碼了~
但有時都會把程式碼改的亂七八糟~這時候這個東西就挺有用的，
可以幫你修正這些錯誤~~
很幸運的，PHP也有支援tidy了~
安裝方式如下 -- ( 偷貼 部落小波 的文章 )
(1) tidy 安裝
我是使用 SuSE, 所以就去找一找 libtidy, libtidy_devel 這兩個 rpm後, 給他裝上去
(2) 安裝 tidy extension in php
./configure --with-tidy=/path/to/libtidy
在您原本的 build options 裏面, 加上 --with-tidy
(3) build 完以後, 就可以開心的用了
下來貼上一些範例
如果是修正 XML 的話~
將在【.....醜醜風的老頭~~】後面的Tag都刪掉
<?php
header("Content-Type:text/xml");
ob_start();
?>
<rss version="2.0">

<description>醜醜風的老頭~~
<?php
$buffer = ob_get_clean();
$tidy_options = array(
'input-xml' => true,
'output-xml' => true,
'indent' => true,
'wrap' => false,
);
$tidy = new tidy();
$tidy->parseString($buffer, $tidy_options,'utf8');
$tidy->cleanRepair();
echo $tidy;
?>
輸出結果，他幫我把少掉的Tag都補上了，真棒。

接著我們將在【.....醜醜風的老頭~~】後面再加上<Error 的Tag
<?php
header("Content-Type:text/xml");
ob_start();
?>
<rss version="2.0">

<description>醜醜風的老頭~~<Error
<?php
$buffer = ob_get_clean();
$tidy_options = array(
'input-xml' => true,
'output-xml' => true,
'indent' => true,
'wrap' => false,
);
$tidy = new tidy();
$tidy->parseString($buffer, $tidy_options,'utf8');
$tidy->cleanRepair();
echo $tidy;
?>
最後的結果就多出了個Error的Tag，
這就不是我想要的結果了，但他的做法應該也沒錯。
不能太強求~他已經很強了~~

下面貼上php官方網站的Sample，是修正HTML (tidy_repair_string)
<?php
ob_start();
?>
<html>
<head>
<title>test</title>
</head>
<body>
<p>error</i>
</body>
</html>
<?php
$buffer = ob_get_clean();
$tidy = tidy_repair_string($buffer);
echo $tidy;
?>
結果它把少的Tag跟錯掉的，都修正好了
<!DOCTYPE html PUBLIC "-//W3C//DTD HTML 3.2//EN"> <html> <head> <title>test</title> </head> <body> <p>error</p> </body> </html>

PS.
這篇文章我重寫了三次，我快被這編輯器搞瘋了~我只要按Ctrl+V，他就會將我textarea裡的 < 給取代掉，天呀~~~~所以我不會再更新這個文章了~~~~
