REBOL [ File: %quote-node-attributes.r Date: 23-11-2020 Title: "Dialect Object Model" Author: daniel murrill Emai: %inetw3--dm--gmail--com Purpose: { This script is used on data Sequence key value pairs with various different syntax styles such as DOM Vars, html,xml,css, objects, arrays, json, rebol series, etc. It attempts to reformat malformed key/value data found in a ^DSL that's usually delimited as objects, arrays, or json statement. It requotes *" "*, and can creates tagged node-elements for look up in Dialect Object Models. Witch then can be set as Vars to be used with rebol-DOM functions. You can allso fine tune your own delimiter rules as characters or words patterens to use with the strip-obj-chars-from() function. ^(DSL: domain specific language) } ] library: [ level: 'intermediate platform: 'all type: function domain: [html vid css json js array] tested-under: 'windows Author: daniel murrill support: none license: none see-also: %HTML-view.r ] ;You can use quote-node-attributes with parameters for more flexibility if needed. ;Replace *does* with *quote-node-attributes: func [(parameters: in-node-element)]* ;Make sure you include *create-tag-element with-these-attributes* ;replace sequence obj. chars. obj-chars: none strip-obj-chars-from: func [node-name obj-chars][ trim node-name remove-head-char? form node-name {"} foreach [-char +char] obj-chars: any [reduce obj-chars [ #"^/" " " " " " " {" , "} {" } {", "} {" } "," " " {" "} {" } {" : "} {: "} {":"} {: "} {":} {:} { " } "" {"[["} {"[[" "} "{" "[" "}" "]" {""} {"} { "} "" " : " ": " ":" " " { =} {=} {=} " " "'" "" "#" " " "'" {"}] ][ replace/all node-name -char +char ] ] ;replace html in-line style-obj chars. tag-tokens: to-hash [ style-obj-chars [ "<" "" {style="} " " {style=} " " " : " { "} ": " { "} ":" {*"} " " {__} {=""} " " "=" {*"} ";" {"*} {""} {"} { "} {"} {*"} { "} {"*} {" } " >" "" ">" "" "rgb" "" {__"} {"} {" "} {"} ] ] remove-tail-char?: func [in-node element][ foreach char element [ all [char = back tail to string! in-node remove back tail in-node] ] ] remove-head-char?: func [in-node element][ type: type? in-node foreach char element [ all [char = any [first to-string in-node form first in-node] to type trim to-string any [attempt [remove in-node] remove form in-node]] ] ] quote-node-attributes: does [with-these-attributes: copy "" remove-tail-char? in-node-element "/" this-node: find/match in-node-element replace node-name: first parse/all in-node-element { =">} "<" "" strip-obj-chars-from in-node-element [ #"^/" " " {:"} {"} ": {" "=true {" { ="" } {="" } { ="} " " {"=""} " " {="" } {" } "://" "&&" ] if find/any this-node "style=" [ parse/all this-node [[to {style="} | to "style="] copy style-obj [thru {;" } | thru {;">} | thru {;>} | thru {;"} | thru {" } | thru {>} | thru "}," | to end] (*style.node: copy style-obj foreach [style-chars found-with-in] tag-tokens/style-obj-chars [replace/all *style.node style-chars found-with-in] replace this-node style-obj *style.node )] ] foreach part replace/all this-node: parse/all this-node {<{} __,=":;[]>} [""] [] [ part: any [if find/match part "'" [ replace/all part "'" ""] part ] strip-obj-chars-from part [" " " " {,} " " "&&" "://" ".
