<p>Created page with "'''Official:''' [https://www.php.net/manual/en/book.xml.php XML Parser] This library consists of an opaque (no public methods or members) class that is read/written by a coll..."</p> <p><b>New page</b></p><div>'''Official:''' [https://www.php.net/manual/en/book.xml.php XML Parser]<br /> <br /> This library consists of an opaque (no public methods or members) class that is read/written by a collection of PHP functions.<br /> <br /> The result of parsing XML content consists of two arrays:<br /> * a flat array of all the tags in the content, with their attributes and values<br /> * an "index" of all the locations in the array where each type of tag occurs<br /> <br /> I haven't been able to puzzle out whether these arrays preserve the structure of the document.<br /> ==Example PHP Code==<br /> <syntaxhighlight lang=php><br /> $onXML = xml_parser_create();<br /> $ok = (bool)xml_parse_into_struct($onXML, $s, $arVals, $arIdx);<br /> if (!$ok) {<br /> $nErr = xml_get_error_code($onXML);<br /> $sErr = xml_error_string($nErr);<br /> $nLine = xml_get_current_line_number($onXML);<br /> $sErr = "could not parse string data: XML error $nErr (line $nLine): ".$sErr;<br /> }<br /> </syntaxhighlight><br /> If successful, the main content is in $arVals and the index is in $arIdx. If not successful, $sErr will show an error message indicating the location in the XML source of the problem.<br /> <br /> There must be only one base-level tag (e.g. {{fmt/xml/tag|data}} below), or there will be an error (something like "premature ending"). Comments can be outside of this, however.<br /> ==Example XML Data==<br /> <syntaxhighlight lang=XML><br /> <br /> <data format="wooz-ui-def" name="ui-def"><br /> <meta><br /> <docs><br /> <link url="https://wooz.dev/Futilities/" /> <br /> </docs><br /> <summary>backs up or restores one or more databases</summary><br /> </meta><br /> <request><br /> <option type="flag" name="do.read"><br /> <summary>back up the database(s)</summary><br /> <cue>-dr</cue><br /> <cue>--do-read</cue><br /> </option><br /> <option type="flag" name="do.write"><br /> <summary>write the given backups to the given database connections</summary><br /> <cue>-dw</cue><br /> <cue>--do-write</cue><br /> </option><br /> <option type="flag" name="get.list"><br /> <summary>just list the available databases</summary><br /> <cue>-gl</cue><br /> <cue>--get-list</cue><br /> </option><br /> </request><br /> </data><br /> </syntaxhighlight><br /> This results in the following arrays:<br /> {| class=wikitable<br /> !
