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. C

#include <C_CkXml.h>

void ChilkatSample(void)
    {
    BOOL success;
    HCkXml xml;
    BOOL autoTrim;

    success = FALSE;

    xml = CkXml_Create();

    // If autoTrim is TRUE, then the content inside an leaf element is trimmed.
    // For example:
    autoTrim = TRUE;
    CkXml_LoadXml2(xml,"<abc><xyz>  123   </xyz></abc>",autoTrim);
    printf("%s\n",CkXml_getXml(xml));

    // 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;
    CkXml_LoadXml2(xml,"<abc><xyz>  123   </xyz></abc>",autoTrim);
    printf("%s\n",CkXml_getXml(xml));

    // 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;
    CkXml_LoadXml2(xml,"<abc><xyz>  123   </xyz></abc>",autoTrim);
    CkXml_putEmitCompact(xml,TRUE);
    printf("%s\n",CkXml_getXml(xml));

    // Output is:

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

    // No Auto-trim + emit compact:
    autoTrim = FALSE;
    CkXml_LoadXml2(xml,"<abc><xyz>  123   </xyz></abc>",autoTrim);
    CkXml_putEmitCompact(xml,TRUE);
    printf("%s\n",CkXml_getXml(xml));

    // Output is:

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


    CkXml_Dispose(xml);
