匹配XPath（）使用C＃正则表达式 [英] XPath matches() using regular expressions in C#

问题描述

更新：我写了我做什么，以源代码和看点，在 - 的添加的XPath 2.0功能和变量.NET的XPath （我的博客）。

有没有办法通过一个正则表达式来匹配（）在.NET中XPath语句

例如：是否的

 /迎风的一室公寓/员工/雇员[匹配（字符串（姓氏），* A-b的XPath [12] C. *'）]
  

解决方案

的XPath 2.0支持的匹配功能。然而，净实现的XPath 1.0。

您将需要添加一个自定义函数来实现匹配。请参见 http://msdn.microsoft.com/en-us/library/ms950806.aspx

它看起来像Mvp.Xml项目：EXSLT.NET模块实现了大部分的XPath 2.0;包括火柴。请参见 http://mvp-xml.sourceforge.net/exslt/

Update: I wrote up what I did, with source code and things to watch for, at - Adding XPath 2.0 functionality and variables to .NET XPath (my blog).

Is there a way to pass a regular expression to matches() for an XPath statement in .NET?

Example: do an xpath of

"/windward-studios/Employees/Employee[matches(string(LastName), '.*A?B[12]C.*')]"

解决方案

XPath 2.0 supports the matches function. However, .Net implements XPath 1.0.

You would need to add a custom function to implement match. See http://msdn.microsoft.com/en-us/library/ms950806.aspx

It looks like the Mvp.Xml Project: EXSLT.NET module implements most of XPath 2.0; including matches. See http://mvp-xml.sourceforge.net/exslt/
