    単純な XML ドキュメントの作成

    この例では、XMLWriter を使ってメモリ上に XML ドキュメントを作る方法を示します。

    例1 単純な XML ドキュメントの作成

    <?php

    $xw     = xmlwriter_open_memory();
    xmlwriter_set_indent($xw, 1);
    $res = xmlwriter_set_indent_string($xw, ' ');

    xmlwriter_start_document($xw, '1.0', 'UTF-8');

    // 最初の要素
    xmlwriter_start_element($xw, 'tag1');

    // 要素 'tag1' の属性 'att1'
    xmlwriter_start_attribute($xw, 'att1');
    xmlwriter_text($xw, 'valueofatt1');
    xmlwriter_end_attribute($xw);

    xmlwriter_write_comment($xw, 'this is a comment.');

    // 子要素を開始
    xmlwriter_start_element($xw, 'tag11');
    xmlwriter_text($xw, 'This is a sample text, ä');
    xmlwriter_end_element($xw); // tag11

    xmlwriter_end_element($xw); // tag1


    // CDATA
    xmlwriter_start_element($xw, 'testc');
    xmlwriter_write_cdata($xw, "This is cdata content");
    xmlwriter_end_element($xw); // testc

    xmlwriter_start_element($xw, 'testc');
    xmlwriter_start_cdata($xw);
    xmlwriter_text($xw, "test cdata2");
    xmlwriter_end_cdata($xw);
    xmlwriter_end_element($xw); // testc

    // 処理命令
    xmlwriter_start_pi($xw, 'php');
    xmlwriter_text($xw, '$foo=2;echo $foo;');
    xmlwriter_end_pi($xw);

    xmlwriter_end_document($xw);

    echo     xmlwriter_output_memory($xw);

    上の例の出力は以下となります。

    <?xml version="1.0" encoding="UTF-8"?>
<tag1 att1="valueofatt1">
 <!--this is a comment.-->
 <tag11>This is a sample text, ä</tag11>
</tag1>
<testc><![CDATA[This is cdata content]]></testc>
<testc><![CDATA[test cdata2]]></testc>
<?php $foo=2;echo $foo;?>
