Hi;

Using VEX codes, how could I remove some letters from end of a string ?

Thanks.

It's a bit tricky, I don't know if there's another way or if it's working for all cases, but the idea is here : transform your name to a string array, remove the values your don't need, and write it back to a string.

Hi,

please have a look at the string manipulation functions in the docs. In your case http://www.sidefx.com/docs/houdini/vex/functions/rstrip.html [www.sidefx.com]
Note the related functions at the bottom of that page.

Edit:

Here's some further info: http://www.sidefx.com/docs/houdini/vex/strings.html [www.sidefx.com]

string a_string = "hello world!";
string thirdbyte = a_string[:-3];

result: hello wor

Hope this helps
Andy

Use functions that start with re_ . They take regex expressions and you should be able to do very complex replacements. Do you have an example string?
