search & replace in a string

Yunqi

Hello Andrew,

How can I remember the pattern, and recall it in the replacement?

e.g.  "inst1.inst2/inst3/net4<1>#1" 

=>  "inst1.inst2\\/inst3\\/net4\\<1\\>\\#1"

pat=pcreCompile("([/<>#])")

string=pcreReplace(pat string "\\\\$_" 0)  ?

Thanks

  • Please read the forum guidelines in future. You posted this in the middle of a 12-year old post, and the guidelines ask you not to do that. So I split your post off into a new thread to avoid confusing the original.

    You can use "\0" (which needs to be escaped for SKILL to "\\0" to match the entire pattern, or "\1" (i.e."\\1" once escaped) to get the first grouped pattern (in parentheses).

    In other words:

    pcreReplace(pat string "\\\\\\1" 0)

    or

    pcreReplace(pat string "\\\\\\0" 0)

    Note that the second will work if your pattern omitted the parentheses and was just:

    pat=pcreCompile("[/<>#]")

    Regards,

    Andrew
