Post your favorite new PARSE examples
With so many new parse features in R3, various types of operations should be documented as simple examples.
For example, while working on website revisions I wanted to use R3 to strip out some of the obsolete HTML tags, such as the old FONT markups like:
<FONT SIZE="4" FACE="Arial, Helvetica">About REBOL's Technology</FONT>
And, in fact, all such FONT tags and end tags, regardless of attributes.
Here's the parse code I used. It also shows how to make two passes over the same file because some of the end tags may not be properly paired.
parse page [
top: while [to "<font" remove thru ">"]
:top while [to "</font>" remove thru ">"]
Notice the use of while rather than some. This is important because remove causes the position index to not advance. See the new note in Parse Summary about this.
Now, I invite you to post your own useful little R3 parse examples. Thanks. We'll collect some of them for use as examples in the parse documentation.
