=={{header|Lua}}==

Using the LuaXML library as available via luarocks. Note that strings in Lua can be enclosed in either single or double quotes to help reduce the need for escape characters.

<lang Lua>require("LuaXML")

function addNode(parent, nodeName, key, value, content)

local node = xml.new(nodeName)

table.insert(node, content)

parent:append(node)[key] = value

end

root = xml.new("CharacterRemarks")

addNode(root, "Character", "name", "April", "Bubbly: I'm > Tam and <= Emily")

addNode(root, "Character", "name", "Tam O'Shanter", 'Burns: "When chapman billies leave the street ..."')

addNode(root, "Character", "name", "Emily", "Short & shrift")

print(root)</lang>

{{out}}

<pre><CharacterRemarks>

<Character name="April">Bubbly: I&apos;m &gt; Tam and &lt;= Emily</Character>

<Character name="Tam O&apos;Shanter">Burns: &quot;When chapman billies leave the street ...&quot;</Character>

<Character name="Emily">Short &amp; shrift</Character>

</CharacterRemarks></pre>

Note also that LuaXML escapes quote marks and apostrophes, which makes the output slightly different to the task requirement. This can be 'fixed' if necessary using Lua's in-built string.gsub function:

<lang Lua>xmlStr = xml.str(root):gsub("&apos;", "'"):gsub("&quot;", '"')

print(xmlStr)</lang>

{{out}}

<pre><CharacterRemarks>

<Character name="April">Bubbly: I'm &gt; Tam and &lt;= Emily</Character>

<Character name="Tam O'Shanter">Burns: "When chapman billies leave the street

..."</Character>

<Character name="Emily">Short &amp; shrift</Character>

</CharacterRemarks></pre>
