获取2个html标签之间的文本c# [英] Get text between 2 html tags c#

问题描述

我正在尝试获取提供的 html (span) 之间的数据(在本例中为 31)

这是原始代码(来自 chrome 中的检查元素)

<块引用>

<span id="point_total" class="tooltip" oldtitle="注意:如果数字是黑色的，你的分数实际上有点负数.别担心，这只是意味着你需要重新开始涂胶."aria- describeby="ui-tooltip-0">31</span>

我有一个包含页面源的富文本框，这里是相同的代码，但在富文本框的第 51 行:

<块引用>

<DIV id=point_display>你有<BR><SPAN id=point_total class=tooltip jQuery16207621750175125325="23" oldtitle="注意:如果数字是黑色的，你的点其实是一点点负数.别担心，这只是意味着您需要重新开始订阅.">17</SPAN><BR>积分 </DIV><IMG style="FLOAT: right" title="获得订阅者" border=0 alt="当人们订阅你时，你会失去一分" src="http://static.subxcess.com/images/page/decoration/remove-1-point.png"></DIV>

我该怎么做呢?我尝试了几种方法，但似乎都不适合我.

我正在尝试从此页面检索点值:http://www.subxcess.com/sub4sub.php该数字会根据您的订阅者而有所不同.

解决方案

你可以非常具体:

var regex = new Regex(@"<span id=""point_total"" class=""tooltip"" oldtitle="".*?"" aria- describeby=""ui-tooltip-0"">(.*?)</span>");var match = regex.Match(@"<span id=""point_total"" class=""tooltip"" oldtitle=""注意:如果数字是黑色的，你的分数实际上有点负数.不要担心，这只是意味着你需要重新开始字幕."" aria- describeby=""ui-tooltip-0"">31</span>");var 结果 = match.Groups[1].Value;

I am trying to get the data between the html (span) provided (in this case 31)

Here is the original code (from inspect elements in chrome)

<span id="point_total" class="tooltip" oldtitle="Note: If the number is black, your points are actually a little bit negative.  Don't worry, this just means you need to start subbing again." aria-describedby="ui-tooltip-0">31</span>

I have a rich textbox which contains the source of the page, here is the same code but in line 51 of the rich textbox:

<DIV id=point_display>You have<BR><SPAN id=point_total class=tooltip jQuery16207621750175125325="23" oldtitle="Note: If the number is black, your points are actually a little bit negative.  Don't worry, this just means you need to start subbing again.">17</SPAN><BR>Points </DIV><IMG style="FLOAT: right" title="Gain subscribers" border=0 alt="When people subscribe to you, you lose a point" src="http://static.subxcess.com/images/page/decoration/remove-1-point.png"> </DIV>

How would I go about doing this? I have tried several methods and none of them seem to work for me.

I am trying to retrieve the point value from this page: http://www.subxcess.com/sub4sub.php The number changes depending on who subs you.

解决方案

You could be incredibly specific about it:

var regex = new Regex(@"<span id=""point_total"" class=""tooltip"" oldtitle="".*?"" aria-describedby=""ui-tooltip-0"">(.*?)</span>");

var match = regex.Match(@"<span id=""point_total"" class=""tooltip"" oldtitle=""Note: If the number is black, your points are actually a little bit negative.  Don't worry, this just means you need to start subbing again."" aria-describedby=""ui-tooltip-0"">31</span>");

var result = match.Groups[1].Value;
