如何修改正则表达式，精准匹配含Supply类词汇的特定HTML属性？

Hey there! Let's sort out that regex issue you're facing with targeting those attribute values containing Supply-related terms. Your original regex was too broad and missed some edge cases—here's how to refine it for precise matches:

The Problem With Your Original Regex #

Your initial pattern had a few gaps:

• It didn’t restrict matches to the inside of double-quoted attribute values, leading to false positives on unrelated text.
• The Supply\Ssite segment incorrectly targeted non-space characters instead of the optional space in "Supply site".
• It lacked clear boundaries for attribute names and their values, making it prone to over-matching.

Fixed Regex for Targeting Attributes #

Use this pattern in your Ctrl+Shift+F search (make sure "Use Regular Expressions" is enabled):

(Text|HeaderText|ToolTip)="([^"]*(?:Supply\s?site|Suppliers|Supply|Supplier)[^"]*)"

Breakdown of the Pattern:

• (Text|HeaderText|ToolTip): Explicitly matches only the attribute names you care about.
• =": Anchors to the start of the attribute’s double-quoted value.
• [^"]*: Matches any characters except double quotes (so we stay inside the attribute value).
• (?:Supply\s?site|Suppliers|Supply|Supplier): A non-capturing group that covers all your target terms—\s? handles the optional space in "Supply site".
• [^"]*: Continues matching until the closing double quote.
• ": Anchors to the end of the attribute value.

Bonus: Case Insensitivity (If Needed) #

If you need to match variations like "supply Site" or "SUPPLIER", add the case-insensitive flag at the start:

(?i)(Text|HeaderText|ToolTip)="([^"]*(?:Supply\s?site|Suppliers|Supply|Supplier)[^"]*)"

How to Replace the Terms #

Once you’ve found all matching attributes, you can replace the target terms in two simple steps:

1. Use the regex above to locate all relevant attributes.
2. For each matched attribute value, run a secondary search-and-replace with this pattern:
   • Find: (Supply\s?site|Suppliers|Supply|Supplier)
   • Replace: depot

This ensures you only swap the exact terms you want, without touching unrelated text or attributes.

Notes to Keep in Mind #

• This regex won’t touch CDATA sections (as requested) since it only targets double-quoted attribute values in your ASPX/ASCX files.
• For your .cs backend files, you’ll need a simpler regex (like (Supply\s?site|Suppliers|Supply|Supplier)) since you’re targeting string literals rather than HTML attributes.
