(Node.js) Scrub Xml

Demonstrates the Scrub method for some common XML cleaning needs.

Note: This example requires Chilkat v9.5.0.77 or greater.

Install Chilkat for Node.js and Electron using npm at Chilkat npm packages for Node.js Chilkat npm packages for Electron on Windows, Linux, MacOSX, and ARM

    // 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:

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

    var xml = new chilkat.Xml();
    var success = xml.LoadXml(s);

    console.log(xml.GetXml());

    // 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");
    console.log(xml.GetXml());

    // 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>
