substRE, substallRE

Format: substRE ( string, pattern, replacement )
Format: substallRE ( string, pattern, replacement )

Purpose: Substitutes regular expression patterns in a string by other strings. All three arguments must be strings. substRE() replaces the first occurrence of the pattern specified by the pattern parameter in string by the replacement parameter.

The substallRE() function works the same, except that it replaces all occurrences of the pattern.

Return Values: Returns the string with the replacements.

Example 1:

heitml input:resulting output:
<? substRE("Hello World ??!","[[:punct:]]",".")>Hello World .?!
<? substallRE("Hello World ??!","[[:punct:]]","!")>Hello World !!!
<? substallRE("Hello World ??!","^.*?o(.*)d.*$","$1")> Worl
<? substallRE("First,Next,Last", "(?x: ^([^,]*) \, ([^,]*) \, ([^,]*) $)", "$3,$2,$1");>Last,Next,First
<? substallRE("<h1>The h1-Tag and the h2-Tag</h1>", "(?x: h(\\d))", "H$1");><H1>The H1-Tag and the H2-Tag</H1>
<? substallRE("<h1>The h1-Tag and the h2-Tag</h1>", "(?x: h((1)|(2)) )()", "H$2$3");><H1>The H1-Tag and the H2-Tag</H1>

Example 2:

<let a="v   w  x    y      z"; b=" +"; c=",";
