正则表达式在此模式中查找文字然后任意文本 [英] Regular expression to find literal and then arbitrary text in pattern of this

问题描述

您好我正在尝试在正则表达式中识别这样的模式：

并替换为相同的 - 最后4个属性。

< polypolygon name =PolyPolygon35height =13width =23left =346top =126visible =true壁纸=falseisreferenceobject =falsebackstyle =solidbackcolor =＃3F3F3Fforecolor =blacklinestyle =solidlinewidth =1patternstyle =nonepatterncolor =blackendcolor =white gradientstop =50gradientdirection =gradientDirectionHorizo​​ntalgradientshadingstyle =gradientHorizo​​ntalFromRight> 
 

引号中的所有数值都不重要只有

< polypolygon as a literal与结尾有关的事项> 
 

我真的需要这个模式与其属性完全匹配（不是引号中的属性值 - 它们不重要），所以我可以用任何东西替换所有最后4个属性。



如果任何人能让我开始正确的方向我可以解决它 - 我试过< pre lang =text>< polypolygon

带有数字计数 - 但这往往会导致问题无法正确识别，所以我的reg-ex可能是好的。

谢谢大家的时间和帮助。

解决方案

PIEBALDConsult是对的：正则表达式是一种非常非常糟糕的方式解析HTML / XML - 它确实是一个问题，错误和挫折的秘诀 - 特别是当你需要在三个月的时间内进行微小的改变时，你已经忘记了那个不可读的正则表达式是如何工作的......

Hello I am trying to identify a pattern like this in regular expression:
And replace with same - last 4 attributes.

<polypolygon name="PolyPolygon35" height="13" width="23" left="346" top="126" visible="true" wallpaper="false" isreferenceobject="false" backstyle="solid" backcolor="#3F3F3F" forecolor="black" linestyle="solid" linewidth="1" patternstyle="none" patterncolor="black" endcolor="white" gradientstop="50" gradientdirection="gradientDirectionHorizontal" gradientshadingstyle="gradientHorizontalFromRight">

All values in quotes are not important only this

<polypolygon as a literal matters along with the ending >

I really need an exact match on this pattern with its attributes (not the attribute values in quotes - they are unimportant) , so I can replace all the last 4 attributes with nothing.

If any one can get me started in the right direction I can work it out - I tried

<polypolygon

with a numeric count - but that tends to get problems not identifying correctly so my reg-ex is probably bad.
Thank you all for your time and help.

解决方案

PIEBALDConsult is right: a regex is a very, very poor way to parse HTML / XML - it really is a recipe for problems, bugs, and frustration - particularly when you need a minor change in three months time, and you have forgotten how that unreadable Regex works...

Have a look at the HTML Agility Pack[^] - it'll probably do most of what you want a lot simpler and quicker.
