GOOGLE NEWS PARSER [英] GOOGLE NEWS PARSER
问题描述
请帮助，我真的使用了我的所有知识，我无法得到它来工作。
让我解释一下：
我需要从GOOGLE新闻中解析，URL，URL文本和描述文字。
每个标题都在谷歌新闻具有相同的结构，它看起来像这样：
< a class =" y"
href =" http：// news .google.com / url？ntc = 05SA0& q = http://www.canada.com/sports/st
ory.html％3Fid％3D5FBD7D23-AA7A-4E4C-AE1D-01CEBC350782" >每个人都希望能够出现这种情况 - 而不是队友Kloden< / a>< br>< font size =" -1"
style =" font-family：arial，sans-serif">< b>
< font color ="＃6f6f6f" style =" font-family：
arial，sans-serif"> Canada.com& nbsp; - < / font> 15& nbsp; minutes& nbsp; ago< / b>< ; br>
BESANCON，法国（美联社） - 寻找一位德国自行车手参加巡回演出de b / b
周日法国领奖台 - 不是大多数人所期待的。 < br>
去吧： http://news.google.com/news/en/us/sports.html 如果需要，请查看
来源。
所以，这是我的抓取链接的解析器（函数）。它的工作原理（谢谢
上帝）我能用这个功能提取所有20个主要标题网址
链接：
公共函数ParseLinks（ByVal HTML As String）As ArrayList
Dim objRegEx As System.Text.RegularExpressions.Regex
Dim objMatch As System.Text.RegularExpressions .Match
Dim arrLinks As New System.Collections.ArrayList
objRegEx = New System.Text.RegularExpressions.Regex（"（？ ：y
[hH] [rR] [eE] [fF] \s * =）（？：[\ s""''] *）（？！＃| [Mm ] ailto | [lL] ocation。| [jJ] avascript |。
* css |。* this \。）（。*？）（？：[\ s>"" '']）"，
System.Text.RegularExpressions.RegexOptions.Ignore Case Or
System.Text.RegularExpressions.RegexOptions.Compil ed）
< br $> b $ b objMatch = objRegEx.Match（HTML）
objMatch.Success
Dim strMatch As String
strMatch = objMatch.Groups（1）.To字符串
arrLinks.Add（strMatch）
objMatch = objMatch.NextMatch（）
结束时
返回arrLinks
结束功能
现在您可能已经猜到了，我的问题是我根本无法用b $ b来编写提取URL TEXT和DESCRIPTION TEXT的相同功能。
请帮助

嗨Jared，
所以当你看看这个google html：
< a class =" y"
href =" http：//news.google.com/url？ntc = 05SA0& q = http ：//www.canada.com/sports/st

< font color ="＃6f6f6f" style =" font-family：

BESANCON，法国（美联社） - 寻找一位德国自行车手参加巡回演出de b / b
周日法国领奖台 - 不是大多数人所期待的。 < br>
这是我需要得到的：
链接：
http://news.google.com/url?ntc=05SA0...D-01CEBC350782
链接文字：每个人都希望Ullrich出现 - 而不是队友
Kloden
描述：法国BESANCON（美联社） - 寻找一位德国自行车手参加星期天在法国环法自行车赛的领奖台 - 只是不是大多数人期望的那个。
这就是我需要的。
我的解析器得到链接。
但我需要获得链接文字和说明。
上帝保佑你们男人如果你能从代码中提取它。

盖伊的，
我会付钱给我们
I realized I am an idiot. Whole saturday wasted on this crazy regex crap, I
can''t even look at it anymore...uff
Honestly, I am even willing to pay to someone who is able to solve this.
Please help, I really used all my knowledge on this and I cannot get it to
work.
Let me explain:
I need to parse, URL , URL TEXT and DESCRIPTION TEXT from GOOGLE NEWS.
Every headline in google news has the same structure and it looks like this:
<a class="y"
href="http://news.google.com/url?ntc=05SA0&q=http://www.canada.com/sports/st
ory.html%3Fid%3D5FBD7D23-AA7A-4E4C-AE1D-01CEBC350782"> Everyone expected
Ullrich to show up - instead it was teammate Kloden</a><br><font size="-1"
style="font-family: arial,sans-serif"><b>
<font color="#6f6f6f" style="font-family:
arial,sans-serif">Canada.com -</font>15 minutes ago</b><br>
BESANCON, France (AP) - Look for a German cyclist to be on the Tour de
France podium Sunday - just not the one most people expected. <br>
go to lets say: http://news.google.com/news/en/us/sports.html and look up
the source if needed.
So, this is my parser (function) for grabbing links. And it works (thanks
God) and I am able to extract with this function all 20 major headlines URL
links:
Public Function ParseLinks(ByVal HTML As String) As ArrayList
Dim objRegEx As System.Text.RegularExpressions.Regex
Dim objMatch As System.Text.RegularExpressions.Match
Dim arrLinks As New System.Collections.ArrayList
objRegEx = New System.Text.RegularExpressions.Regex("(?:y
[hH][rR][eE][fF]\s*=)(?:[\s""'']*)(?!#|[Mm]ailto|[lL]ocation.|[jJ]avascript|.
*css|.*this\.)(.*?)(?:[\s>""''])",
System.Text.RegularExpressions.RegexOptions.Ignore Case Or
System.Text.RegularExpressions.RegexOptions.Compil ed)
objMatch = objRegEx.Match(HTML)
While objMatch.Success
Dim strMatch As String
strMatch = objMatch.Groups(1).ToString
arrLinks.Add(strMatch)
objMatch = objMatch.NextMatch()
End While
Return arrLinks
End Function
Now as you probably guessed already, my problem is that I am simply not able
to write the same function for extraction of URL TEXT and DESCRIPTION TEXT.
please help

Krakatioison,
What do you mean by url, url test and description text. show me which
portions you need.

Hi Jared,
so when you look at this google html:
<a class="y"
href="http://news.google.com/url?ntc=05SA0&q=http://www.canada.com/sports/st
ory.html%3Fid%3D5FBD7D23-AA7A-4E4C-AE1D-01CEBC350782"> Everyone expected
Ullrich to show up - instead it was teammate Kloden</a><br><font size="-1"
style="font-family: arial,sans-serif"><b>
<font color="#6f6f6f" style="font-family:
arial,sans-serif">Canada.com -</font>15 minutes ago</b><br>
BESANCON, France (AP) - Look for a German cyclist to be on the Tour de
France podium Sunday - just not the one most people expected. <br>
This is what I need to get:
LINK:
http://news.google.com/url?ntc=05SA0...D-01CEBC350782
LINKS TEXT: Everyone expected Ullrich to show up - instead it was teammate
Kloden
DESCRIPTION: BESANCON, France (AP) - Look for a German cyclist to be on the
Tour de France podium Sunday - just not the one most people expected.
That is what I need.
My parser gets the LINK.
But I need to get LINKS TEXT and DESCRIPTION.
God bless you men If you can extract it from the code.
