字符串过滤问题

[IT流渊]

字符串过滤问题
有一字符串：
<IMG alt=\"\" hspace=50 src=\"F:\\OLDData\\网页制作知识\\网页制作知识\\导入数据库.jpg\" align=baseline vspace=40 border=0>5235风光好好
<IMG alt=\"\" hspace=50 src=\"F:\\OLDData\\网页制作知识\\网页制作知识\\导入数据库2.jpg\" align=baseline vspace=40 border=0>"5858泰国人天天

想通过过滤得到下面的字符串：
{导入数据库.jpg}5235风光好好{导入数据库2.jpg}5858泰国人天天

想不到好方法~

同志们 帮忙 看看哇~~~~

在哪里用的js? vs.net?什么版本？2005?2008?

[IT流渊]

不好意意思
delegate(Match m)
{
return string.Format("{{{0}}}{1}", m.Groups["file"].Value, m.Groups["text"].Value);
});
这个问题
就是 字符串经过 处理
出来 没有变化
一进一出 没有变化

[IT流渊]

代码 没问题
就是没起作用

[兔子-顾问]

你要贴你的例子来。你用我给你的例子没结果么？你代码贴来。

private string DoContentText(string fj)
{

if (!fj.Contains("<IMG alt="))
{
return fj;
}
string result = System.Text.RegularExpressions.Regex.Replace(fj, @"(?is)<img.*?src="".+?(?<file>[\w.]+)""[^>]*>(?<text>[^<]+)",delegate(System.Text.RegularExpressions.Match m){return string.Format("{{{0}}}{1}", m.Groups["file"].Value, m.Groups["text"].Value);});

return result;
}
这个是我的处理函数

[IT流渊]

另外 我的vs2008的

[兔子-顾问]

调用的也贴来。才知道你用什么数据测试出没结果的。

[IT流渊]

恩找到原因了 )<img.*?src="".+?(?<

我的字符串里 img是大写的 把 它改成大写 就ok 了 谢谢~~

[兔子-顾问]

拜托像我这样贴，方便大家阅读。

static void Main(string[] args)
{
    string test = "<IMG alt=\"\" hspace=50 src=\"F:\\OLDData\\网页制作知识\\网页制作知识\\导入数据库.jpg\" align=baseline vspace=40 border=0>5235风光好好\r\n<IMG alt=\"\" hspace=50 src=\"F:\\OLDData\\网页制作知识\\网页制作知识\\导入数据库2.jpg\" align=baseline vspace=40 border=0>\"5858泰国人天天";
    Console.WriteLine(DoContentText(test));
    Console.ReadKey();
}

private static string DoContentText(string fj)
{

    if (!fj.Contains("<IMG alt="))
    {
        return fj;
    }
    string result = System.Text.RegularExpressions.Regex.Replace(fj, @"(?is)<img.*?src="".+?(?<file>[\w.]+)""[^>]*>(?<text>[^<]+)", delegate(System.Text.RegularExpressions.Match m) { return string.Format("{{{0}}}{1}", m.Groups["file"].Value, m.Groups["text"].Value); });

    return result;
}

结果：
{导入数据库.jpg}5235风光好好
{导入数据库2.jpg}"5858泰国人天天


------------------------------------------------------------------

以上代码都是运行测试过，。你贴进去一定有结果的。你如果测试过我给你的，你不会回复说没结果。如果说不对，像我这样给出完整测试例子。否则谁猜得到你的问题是什么？

[兔子-顾问]

和大小写无关。我给你的正则忽略大小写的。

[IT流渊]

呵呵 我也试 用C#语言 发表 不知怎么弄~

非常感谢 逍遥兄 ....

[暖枫无敌]

我顶

[xinv19shi]

顶起！！

[xandercheng]

等候高手

c中存放源字符串。

string result="{导入数据库.jpg}";
int index=c.IndexOf("5235风光好好");
result+=c.Substring(index,8);
result+="{导入数据库2.jpg}";
index=c.IndexOf("5858泰国人天天");
result+=c.Substring(index,9);

result为最终字符串。

Substring+stringbuffer

[马老虎]

可以使用正则匹配截取！
