如何在Asp.Net C中替换H＃ [英] How Can I Replace Html In Asp.Net C#

问题描述

我有一个HTML字符串，如

< P style =MARGIN-BOTTOM：12px; TEXT-ALIGN：center ; MARGIN-LEFT：0px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana';  FONT-重量：正常; FONT-STYLE：正常>自动化以简化您的业务流程< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana';  FONT-WEIGHT：normal; FONT-STYLE：normal>简化整个保险流程工作流程< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana';  FONT-WEIGHT：正常; FONT-STYLE：正常>强大的报告符合所有联邦标准< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Arial Black';  FONT-WEIGHT：normal; FONT-STYLE：normal>不同业务领域之间的数据流< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Arial Black';  FONT-WEIGHT：正常; FONT-STYLE：正常>节省时间，成本和资源< / SPAN>< / P> 

i想要处理这个HTML字符串

并想要输出像

< P style =MARGIN-BOTTOM：12px; TEXT-ALIGN：center; MARGIN-LEFT：0px; MARGIN-TOP：0px; LINE-高度：1.1499>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana'！重要;  FONT-WEIGHT：正常; FONT-STYLE：正常>自动化简化您的业务流程< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana'！重要;  FONT-WEIGHT：正常; FONT-STYLE：正常>简化整个保险流程工作流程< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Verdana'！重要;  FONT-WEIGHT：正常; FONT-STYLE：正常>强大的报告符合所有联邦标准< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Arial Black'！重要;  FONT-WEIGHT：正常; FONT-STYLE：正常>不同业务领域之间的数据流< / SPAN>< / P> 
< P style =MARGIN-BOTTOM：12px; MARGIN-TOP：0px; LINE-HEIGHT：1.1499; MARGIN-RIGHT：0px>< SPAN style =FONT-SIZE：16px;  FONT-FAMILY：'Arial Black'！重要;  FONT-WEIGHT：正常; FONT-STYLE：正常>节省时间，成本和资源< / SPAN>< / P> 

我想添加！在CSS的每个字体系列属性中很重要。



我怎样才能做到这一点。



谢谢

解决方案

使用正则表达式：

  public   static 正则表达式正则表达式=  new 正则表达式（
  （？< ; = FONT-FAMILY：\\\\）（？< Font>'。+'）（？=;），
 RegexOptions.IgnoreCase 
 | RegexOptions.Multiline 
 | RegexOptions.CultureInvariant 
 | RegexOptions.IgnorePatternWhitespace 
 | RegexOptions.Compiled 
）; 
  public   static   string  regexReplace =   

{Font}！mportant;

// 使用替换模式替换InputText中的匹配文本
string result = regex.Replace（InputText，regexReplace）;

修订版：

  public  静态正则表达式regex = 新正则表达式（
  （？< = FONT-FAMILY：\\\\）（？< Font>'。+？'）（？=;），
 RegexOptions .IgnoreCase 
 | RegexOptions.Multiline 
 | RegexOptions.CultureInvariant 
 | RegexOptions.IgnorePatternWhitespace 
 | RegexOptions.Compiled 
）; 
  public   static   string  regexReplace =   

{Font}！mportant;

// 使用替换模式替换InputText中的匹配文本
string result = regex.Replace（InputText，regexReplace）;

I have a HTML String like

<P style="MARGIN-BOTTOM: 12px; TEXT-ALIGN: center; MARGIN-LEFT: 0px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana'; FONT-WEIGHT: normal; FONT-STYLE: normal">Automate to streamline your business process</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana'; FONT-WEIGHT: normal; FONT-STYLE: normal">Streamlining the entire insurance process workflow</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana'; FONT-WEIGHT: normal; FONT-STYLE: normal">Powerful reporting that meets all Federal Standards</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Arial Black'; FONT-WEIGHT: normal; FONT-STYLE: normal">Data flow among different business areas</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Arial Black'; FONT-WEIGHT: normal; FONT-STYLE: normal">Savings on time‚ cost and resources</SPAN></P>

i Want to process this HTML string
and want a output like

<P style="MARGIN-BOTTOM: 12px; TEXT-ALIGN: center; MARGIN-LEFT: 0px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana' !mportant; FONT-WEIGHT: normal; FONT-STYLE: normal">Automate to streamline your business process</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana' !mportant; FONT-WEIGHT: normal; FONT-STYLE: normal">Streamlining the entire insurance process workflow</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Verdana' !mportant; FONT-WEIGHT: normal; FONT-STYLE: normal">Powerful reporting that meets all Federal Standards</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Arial Black' !mportant; FONT-WEIGHT: normal; FONT-STYLE: normal">Data flow among different business areas</SPAN></P>
<P style="MARGIN-BOTTOM: 12px; MARGIN-TOP: 0px; LINE-HEIGHT: 1.1499; MARGIN-RIGHT: 0px"><SPAN style="FONT-SIZE: 16px; FONT-FAMILY: 'Arial Black' !mportant; FONT-WEIGHT: normal; FONT-STYLE: normal">Savings on time‚ cost and resources</SPAN></P>

I want to add !important in Each Font-Family Attribute of CSS .

How can i accomplish this.

Thanks

解决方案

Use a regex:

public static Regex regex = new Regex(
      "(?<=FONT-FAMILY:\\s)(?<Font>'.+')(?=;)",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );
public static string regexReplace = "

{Font} !mportant"; // Replace the matched text in the InputText using the replacement pattern string result = regex.Replace(InputText,regexReplace);

Revised version:

public static Regex regex = new Regex(
      "(?<=FONT-FAMILY:\\s)(?<Font>'.+?')(?=;)",
    RegexOptions.IgnoreCase
    | RegexOptions.Multiline
    | RegexOptions.CultureInvariant
    | RegexOptions.IgnorePatternWhitespace
    | RegexOptions.Compiled
    );
public static string regexReplace = "

{Font} !mportant"; // Replace the matched text in the InputText using the replacement pattern string result = regex.Replace(InputText,regexReplace);
