使用正则表达式和VS Replace选项更新Asp.NET Project中的href

Question

I have project on Asp.NET Web Forms.

I need to update hrefs on Views. This hrefs is for Downloading, so on click user are able to save document, in my case .pdf files. So i need to change href-Links just for target pdf-files

Example : Now href is in next format:

href="/about/news/downloads/Ingram%20Announcement_5.31.07.pdf"

What is needed : Add

<%=MyProject.Core.Common.PublisherConfigurationManager.Content%>

instead of first / in href link (possible href link hasn't / as first symbol).

Expected result is:

href="<%=MyProject.Core.Common.PublisherConfigurationManager.Content%>
    about/news/downloads/Ingram%20Announcement_5.31.07.pdf"

How can i make this update using Ctrl + Shift + F and Regex?

Work in VS 2013

Answer 1

This will match any href ending in ".pdf".

Regex: href\\=\\"/?([^"]+\\.pdf)\\" .

Note this will match the optional / but not capture it. Then it finds at least 1 character which is not a quote to close the href and ends with .pdf" . The path without the leading / and filename are then stored in match position $1

Replacement: href="<%=MyProject.Core.Common.PublisherConfigurationManager.Content%>$1"

If you want to match other extensions in addition to pdfs, you can just add an OR clause | to the regex. For example href\\=\\"/?([^"]+\\.(pdf|jpg))\\" will match pdfs and jpgs. The replacement does not need to change

Answer 2

按ctrl + h并在搜索词中输入href="/在替换词中输入href="/ href="<%=MyProject.Core.Common.PublisherConfigurationManager.Content%> 。
