抓取页面的内容
我已经抓取了某个页面,已经把内容局限在以下的这个表里,请问2个问题:
1)如何抓取每对的 "英文名称 "和 "中文名称 "
2)如何抓取PAGE数(page= "xx ")

[解决办法]
VS 2003 下调试结果：
英文名称：Acidcyanine中文名称：酸性花青[染料]
英文名称：Actualcount(=actualyarncount)中文名称：实际支数,实际纱支
英文名称：actualyarncount中文名称：实际纱支
英文名称：Aeratedyarn中文名称：气泡纱[由含有气泡的纤维构成]
英文名称：agfapolyamide中文名称：阿克发聚酰胺
英文名称：airentangledyarn中文名称：气流喷射交缠丝《化纤》
英文名称：Airjetbulkyyarn中文名称：喷气（法）膨松变形丝
英文名称：air-bulkedyarn中文名称：喷气膨化纱

一个Form1 一个button1 一个 textBox1
private void button1_Click(object sender, System.EventArgs e)
{
StreamReader f1=new StreamReader( "1.txt ",Encoding.Default);
string str1=f1.ReadToEnd();
this.textBox1.Text=str1;
MatchCollection str2=Regex.Matches(str1, " <TR> .*?英文名称.*? </TR> .*? <TR> .*?中文名称.*? </TR> ",RegexOptions.Singleline);
MessageBox.Show( "找到 "+str2.Count.ToString()+ "匹配项 ");
this.textBox1.Text= " ";
foreach (Match str in str2)
{
string str3=Regex.Replace(str.ToString(), "(\\s)|( <.*?> )|( ) ", " ",RegexOptions.Singleline);
this.textBox1.Text+=str3+ "\r\n ";
}
}
[解决办法]
这个的正则要怎样写:
<a href= '/dictionary/result.asp?page=正整数&Blur=1&Keyword=任意字符 ' > [正整数] </a>
正整数和任意字符要怎样表达?
<a href= '/dictionary/result.asp?page=(\d)+?&Blur=1&Keyword=.*? ' > [(\d)+?] </a>
使用时注意转义符
