given String 'Foo <nowiki>Bar</nowiki> Baz' yield String 'Foo Baz'

Hi folks,

I did not see anything obvious to do the above, and I am writing some really ugly code to get the task done.

Is anybody aware of a simple message send like...

'Foo <nowiki>Bar</nowiki> Baz' removeAllBetween:'<nowiki>' and: '</nowiki>'.

thx in advance.

a := 'Foo <nowiki>Bar</nowiki> Baz'.

s:= Scanner new.

toks := s typedScanTokens: a.

sel := ''.

level := 0.

toks do: [:t|

t caseOf: {

[#<] -> [level:=1].

[#</] -> [level:=2].

[#>] -> [level =2 ifTrue:[sel:=sel, ' '. level:=0]].

}

otherwise: [

level = 0 ifTrue:[sel := sel, t]

sel

For a one-off case, maybe some of the #findTokenXXX methods? Maybe #parseTokens: would help - it's part of the HTML handling stuff.

For bigger duty, probably time to look into the regexp methods; there's a bunch of likely suspects in the messagenamebrowser.

You can rely on your own parsing, but if you're at all likely to expand into a broader HTML space then explore the HTML Framework. For example, this doesn't do what you want but it gets you close and is generally powerful enough for any and all HTML parsing tasks.

(HTMLParser parse: 'Foo <nowiki>Bar</nowiki> Baz') contents last textualContents => 'Foo Bar Baz'
