我需要从rss提要描述,但始终得到一个描述与路径图像。
RSS提要是:
<description>
<![CDATA[<img src="http://example.com/img/1/title/1967304.jpg"/> Ukrainian forces launch an "anti-terrorist operation" after pro-Russian gunmen seize buildings in the eastern part of the country.]]>
</description>我有密码:
if (this._groups.Count != 0)
return;
SyndicationClient client = new SyndicationClient();
Uri feedUri = new Uri("url_feed");
var feed = await client.RetrieveFeedAsync(feedUri);
foreach (SyndicationItem item in feed.Items)
{
string data = string.Empty;
if (feed.SourceFormat == SyndicationFormat.Rss20)
{
// Get description
data = item.Summary.Text;
}
Regex regx = new Regex("http://([\\w+?\\.\\w+])+([a-zA-Z0-9\\~\\!\\@\\#\\$\\%\\^\\&\\*\\(\\)_\\-\\=\\+\\\\\\/\\?\\.\\:\\;\\'\\,]*)?.(?:jpg|bmp|gif|png)"
, RegexOptions.IgnoreCase);
string filePath = regx.Match(data).Value;
DataGroup group = new DataGroup(item.Id,
item.Title.Text,
item.Links[0].Uri.ToString(),
filePath.Replace("small", "large"),
data.Split(new string[] { "<br>" }, StringSplitOptions.None)[0].ToString());
this.Groups.Add(group);
}输出是(在文本块中):
< img src="">http://example.com/img/1/title/1967304.jpg">乌克兰部队在亲俄枪手占领乌克兰东部的建筑物后发动了“反恐行动”。
我只需要文字,没有文字与img路径。

如果您的文本不包含“<”或“doesn>”,您可能会发现这是有用的:
使用:
using System.Text.RegularExpressions;片段:
// Do your stuff to get the description
string description = "< img src=\"http://example.com/img/1/title/1967304.jpg\"> Ukrainian forces launch an \"anti-terrorist operation\" after pro-Russian gunmen seize buildings in the eastern part of the country.";
string cleaned = Regex.Replace(description, @"<[^>]*>", String.Empty, RegexOptions.IgnoreCase).Trim();
Console.WriteLine(cleaned);https://stackoverflow.com/questions/23040422
