XML Lint Validation Shared Encoding Tutorial<\/p><\/div>\n

There are a lot of web applications we’ve been involved with that …<\/p>\n

    \n
  1. try to avoid (what we are most “peeved” by, as an issue)<\/font> gobbledegook when dealing with non-ascii content we try, encoding wise, to corral towards UTF-8 encoding … and today we …<\/li>\n
  2. add sharing and collaboration functionality, via email or SMS, to our current XML Lint Validation web application<\/a> development<\/li>\n<\/ol>\n

    … hence the “Shared Encoding” curiosity in our blog posting title … well, you had to be there …<\/font> today, in the days after yesterday’s XML Lint Validation SelectionChange Tutorial<\/a> …<\/p>\n

    Fancy a pertinent riddle?<\/p>\n

    \nWhat is always coming but never arrives?\n<\/p><\/blockquote>\n

    Anyone, anyone<\/a>?<\/p>\n

    Yes, Hoagy<\/a>, do you have an answer?<\/p>\n

    \nNo Bull Cow No Bull\n<\/p><\/blockquote>\n

    Well, that’s quite rude and wise all at once, Hoagy! Anybody else? Yes, Edward<\/a>, your answer …<\/p>\n

    \nRearrange the sycophant!\n<\/p><\/blockquote>\n

    … has merit too! But wish one of you would enunciate … use your words …

    You have the answer Tatsumi<\/a>? Well …<\/p>\n

    \nToday\n<\/p><\/blockquote>\n

    … excellent try! But no, not quite. The answer is …<\/p>\n

    \nTomorrow\n<\/p><\/blockquote>\n

    But, five points to Hufflepuff, and we add today’s voucher for a cup of tea<\/sub> (no rushing please)<\/font>!<\/p>\n

    But, back to business, as far as the encoding issue (of gobbledegook) goes, we mucked around thinking the fault lay with “meta” tags, and such, in the parent, until we relooked at the FileReader arrangements we had going back at a changed<\/a> client_browsing.htm<\/a> client side HTML and Javascript inhouse helper. We were always using readAsDataURL()<\/a> method for this URL call containing “straighttext=” argument pattern, but we found more success starting to use readAsText()<\/a> method for HTML and XML data inputs. Makes sense really! Now we go<\/font> …<\/p>\n


    \n blob.push(file.slice(start, stop + 1));
    \n if (parent.document.getElementById('txtresultout')) {
    \n reader[ij].readAsText(blob[ij]);
    \n } else {
    \n if (document.URL.indexOf('straighttext=') != -1) {
    \n if (window.parent) {
    \n if (parent.document.getElementById('result1') && parent.document.getElementById('result2')) {
    \n reader[ij].readAsText(blob[ij]);
    \n } else {
    \n reader[ij].readAsDataURL(blob[ij]);
    \n }
    \n } else {
    \n reader[ij].readAsDataURL(blob[ij]);
    \n }
    \n } else {<\/font>
    \n reader[ij].readAsDataURL(blob[ij]);
    \n }
    \n }<\/font>
    \n<\/code><\/p>\n

    … as well as<\/font> …<\/p>\n


    \n reader[ij].onloadend = (function(mfile) {
    \n return function(evt) {
    \n var dp='', ds=dssuffix, slideshowparent=false, ssuffix='0', nsuffix='2', blnks=' ', xhsf='', zhsfs=[];
    \n var tomt='video\/mp4', thext='', ithext=0;
    \n if (evt.target.readyState == FileReader.DONE) { \/\/ DONE == 2
    \n if (document.URL.indexOf('straighttext=') != -1) {
    \n if (window.parent) {
    \n if (parent.document.getElementById('result1') && parent.document.getElementById('result2')) {
    \n if (parent.document.getElementById('result1').innerHTML == '') {
    \n parent.document.getElementById('result1').innerHTML=(evt.target.result); \/\/ used to use window.atob and .replace('data:application\/octet-stream;base64,', '')
    \n } else {
    \n parent.document.getElementById('result2').innerHTML=(evt.target.result); \/\/ retest earth_scanner.html
    \n }
    \n }
    \n }
    \n }<\/font>
    \n\/\/ rest of FileReader.DONE code follows
    \n } };
    \n })(files[ij]);
    \n<\/code><\/p>\n

    … as a solution to this issue, putting a smile to many an emoji<\/a> out there.<\/p>\n

    And as far as our email or SMS sharing goes, we avoided any need for PHP mail ideas by starting to involve hashtagged versions of the incoming XML or HTML input to the XML Lint validator …<\/p>\n
