Scrub Xml

See more XML Examples

Demonstrates the Scrub method for some common XML cleaning needs.

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

Zig

const std = @import("std");
const chilkat = @import("chilkat");

pub fn main(init: std.process.Init) !void {
    const alloc = init.arena.allocator();

    // 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:

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

    const xml = try chilkat.Xml.init();
    defer xml.deinit();
    try xml.loadXml(s);

    std.debug.print("{s}\n", .{try xml.getXml(alloc)});

    // 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");
    std.debug.print("{s}\n", .{try xml.getXml(alloc)});

    // 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>
