Java - RegEx to replace text between dollar signs

Question

I am using JAVA and want to replace every instance of text between dollar signs. For example:

1st equation $\\frac{1}{\\mu -1}\\frac{2\\pi }{\\lambda }x$ 
2nd eq         


        

Answer 1

I believe it would be something like this...

myString.replaceAll("\\$[^$]*\\$", 
     "<img src=\"http://latex.codecogs.com/gif.latex?$0 \" border=\"0\"/>"

The $0 in the replacement string should match the capturing group in the search regex per...

String.replaceAll

Matcher.replaceAll

Answer 2

The regex used in C# is the same for Java, except that you need to double escape $.

"\\$([^\\$]*)\\$"
