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($xw); // tag11xmlwriter_end_element($xw); // tag1// CDATAxmlwriter_start_element($xw, 'testc');xmlwriter_write_cdata($xw, "This is cdata content");xmlwriter_end_element($xw); // testcxmlwriter_start_element($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;?>
