如何使用正则表达式仅大写参考文献Title字段内的单词？

Let's fix your regex issue and get those title words properly capitalized!

Why Your Original Regex Didn't Work #

Your regex (?<=Title)(\b.+?\b) only targets the first word after "Title" because:

• The non-greedy .+? stops at the first word boundary (\b) right after "Title"
• It doesn't restrict matches to the content inside the {} brackets, so it could accidentally pick up unrelated text elsewhere in your file

Correct Approach: Target Title Content & Capitalize Each Word #

We need to first isolate the text inside Title = { ... }, then capitalize the first letter of every word (including those after hyphens, like bi-elemental → Bi-Elemental).

1. For VS Code (Most Flexible)

Enable regex mode (click the .* button in the search/replace panel):

• Find: (?<=Title = {)(.*?)(?=})
• Replace: ${1/(^|\s|-)([a-z])/$1\u$2/g}

This works by:

• Capturing all text inside the title brackets
• Running a nested regex on that captured text to find:
  • The start of the string, a space, or a hyphen (^|\s|-)
  • Followed by a lowercase letter ([a-z])
• Replacing with the preceding character plus the uppercase version of the letter ($1\u$2), applied globally (g)

2. For Sublime Text

Enable regex mode:

• Find: (Title = {)(.*?)(})
• Replace: $1${2/(\b|-)([a-z])/$1\u$2/g}$3

3. For Notepad++

Enable Perl-compatible regex (check the box in the replace dialog):

• Find: (?<=Title = {)(\b[a-z]|[-][a-z])
• Replace: \u$0

This directly matches every lowercase letter that starts a word (or comes after a hyphen) inside the title brackets, then uppercases it.

Example Result #

Original line:

... Title = {Direct synthesis of antimicrobial coatings based on tailored bi-elemental nanoparticles}, journal={APL Mat.}, ...

After replacement:

... Title = {Direct Synthesis of Antimicrobial Coatings Based on Tailored Bi-Elemental Nanoparticles}, journal={APL Mat.}, ...
