YQL +表 + X路径
我正在与 YQL 合作。我了解如何对网页进行简单查询并使用 xpath 选择内容。
例如： select * from html where url="http://www.animeclick.it/manga.php?xtit=Ranmaru+XXX" 和 xpath="/html/body/ div/table/tr/td/table/tr/td/div/div/img[包含(@src,'manga')]"。
现在，这种方法存在局限性。我无法登录该站点，无法在页面中重复不同的信息（我知道可以进行更多查询或添加新的 xpath 表达式）并且我无法格式化输出结果
(like inside div this content :
"<p> Hello <a src="#"> Boy!</a></p>" ,
where in this case i need the text "Hello boy")
如何在此范围内使用 YQL OPEN TABLE！ ??！
I'm working with YQL. I understand how to make a simple query to a web page and select content with xpath.
For example: select * from html where url="http://www.animeclick.it/manga.php?xtit=Ranmaru+XXX" and xpath="/html/body/div/table/tr/td/table/tr/td/div/div/img[contains(@src,'manga')]".
Now, there are limitation in this approach. I can't make login to the site, can't repeat different information in the page (I know can make more query or add new xpath expression) and I can't format output result
(like inside div this content :
"<p> Hello <a src="#"> Boy!</a></p>" ,
where in this case i need the text "Hello boy")
How to use YQL OPEN TABLE for this scope!??!
