Lua Requires Chilkat v9.5.0.77+

Scrub Xml

See more XML Examples

Demonstrates the Scrub method for some common XML cleaning needs. Lua

local chilkat = require("chilkat")

-- The Scrub method has options for trimming whitespace from the ends of attributes and content,
-- trimming inside whitespace, and for case conversion for tags and attribute names.

-- Trimming inside whitespace is defined as replacing CR, LF, and tab chars with SPACE chars, and
-- removing extra SPACE chars so that at most one SPACE separates non-SPACE chars.

-- For example, load the following XML:

local s = "<xyz><td class=\" colHoldingPercent col7\" style=\"border-bottom-color: rgb(221, 221, 221);               border-image-outset: 0;  \"> abc\r\n123    456</td></xyz>"

local xml = chilkat.Xml.new()
local success = xml:load_xml(s)

print(xml:get_xml())

-- The XML before scrubbing is:

-- <xyz>
--     <td class=" colHoldingPercent col7" style="border-bottom-color: rgb(221, 221, 221);               border-image-outset: 0;  ">abc
-- 123    456</td>
-- </xyz>

xml:scrub("AttrTrimEnds,AttrTrimInside,ContentTrimEnds,ContentTrimInside")
print(xml:get_xml())

-- The XML after scrubbing is:

-- <?xml version="1.0" encoding="utf-8"?>
-- <xyz>
--     <td class="colHoldingPercent col7" style="border-bottom-color: rgb(221, 221, 221); border-image-outset: 0;">abc 123 456</td>
-- </xyz>
