[REBOL] shifting characters in rejoin Re:

From: kgd03011:nifty:ne:jp at: 5-Oct-2000 10:16

Hi Ryan, Andrew Martin already answered you, but maybe this provides a little different perspective ... The results look strange because the < and > aren't part of the tag! data, they just delimit it.
>> length? <TAG>
== 3 When you do markup-string: rejoin [open-tag data/name close-tag] the first item in REJOIN's block argument is a tag, so the result is a tag. But before close-tag is appended, it is formed to a string, which causes the delimiting < > to actually become characters of data. A tag! is meant to represent only one tag. If you want to have more than one tag in an HTML element, you need to make a string. So it's very easy to correct your function. Replace the line quoted above with: markup-string: rejoin ["" open-tag data/name close-tag] Eric
