Auto-Trim XML Content when Loading

See more XML Examples

This example explains the "autoTrim" argument that is passed to a method such as LoadXml2. Swift

func chilkatTest() {
    var success: Bool = false

    let xml = CkoXml()!

    // If autoTrim is true, then the content inside an leaf element is trimmed.
    // For example:
    var autoTrim: Bool = true
    xml.loadXml2(xmlData: "<abc><xyz>  123   </xyz></abc>", autoTrim: autoTrim)
    print("\(xml.getXml()!)")

    // Output is:
    // (notice the SPACE chars before and after "xyz" are trimmed)

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc>
    //     <xyz>123</xyz>
    // </abc>

    // If autoTrim is false, then the content inside leaf elements are not trimmed.
    autoTrim = false
    xml.loadXml2(xmlData: "<abc><xyz>  123   </xyz></abc>", autoTrim: autoTrim)
    print("\(xml.getXml()!)")

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc>
    //     <xyz>  123   </xyz>
    // </abc>

    // --------------------------------------------------------------------
    // The EmitCompact property controls whether XML is emitted indented (pretty-printed)
    // or compact.  For example:

    // Auto-trim + emit compact:
    autoTrim = true
    xml.loadXml2(xmlData: "<abc><xyz>  123   </xyz></abc>", autoTrim: autoTrim)
    xml.emitCompact = true
    print("\(xml.getXml()!)")

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc><xyz>123</xyz></abc>

    // No Auto-trim + emit compact:
    autoTrim = false
    xml.loadXml2(xmlData: "<abc><xyz>  123   </xyz></abc>", autoTrim: autoTrim)
    xml.emitCompact = true
    print("\(xml.getXml()!)")

    // Output is:

    // <?xml version="1.0" encoding="utf-8" ?>
    // <abc><xyz>  123   </xyz></abc>
