当定义很多个样式时，往往在页面中显示优先级高的样式，一些定义的样式就被屏蔽了，所以要合并自定义样式到一个span中，
protected string MergeStyle(string s)
{
string pattern = @"(<span[\s\S]*><span[\s\S]*>)[\u4e00-\u9fa5]+(</span></span>)+";
Regex regex = new Regex(pattern);
MatchCollection matches = Regex.Matches(s, pattern, RegexOptions.IgnoreCase | RegexOptions.ExplicitCapture);
foreach (Match m in matches)
{
string str = m.ToString();
string p1 = @"[\u4e00-\u9fa5]+";
Regex r1 = new Regex(p1);
Match m1 = r1.Match(str);
string s1 = m1.ToString();
System.Collections.Generic.List<int> al = new System.Collections.Generic.List<int>();
char[] strChars = str.ToCharArray();
for (int i = 0; i < strChars.Length; i++)
{
if (strChars[i] == '\"')
{
al.Add(i);
}
}
string style = "";
int tag = 1;
for (int i = 0; i < al.Count/2; i++)
{
if (i == 0)
{
style= str.Substring(al[i] + 1, al[i + 1] - al[i] - 1)+";";
}
else {
style+= str.Substring(al[tag + 1] + 1, al[tag + 2] - al[tag + 1] - 1)+";";
tag = tag + 2;
}
}
string newStyle = "<span style=\" " + style + "\" >" + s1 + "</span>";
s = regex.Replace(s, newStyle);
}
return s;
}
目前还有bug,当一些特殊情况就不能合并。在改进中
