У меня есть строка XML следующим образом:
<?xml version="1.0" encoding="utf-8"?> <document id="0" name="RegSimple" Version="0.1"> <Description> Configuration document for simple registration of incidents. This document will contain both the fixed and the user-defined fields to show on the registration screen. </Description> <Fields> <Textbox id="1" name="IncidentID" visibility="Hidden" width="500" displayreadonly="False" /> <Comment id="200" height="10" name="c1" caption=" " /> <Header id="100" name="Header" caption="Description" /> <Radiobox id="2" name="Type" caption="Feedback type" width="500" type="19" displayreadonly="true"></Radiobox> <Textbox id="3" name="Description" caption="My feedback" width="500" height="75" multiline="True" required="True" displayreadonly="True" /> <Textbox id="4" name="Incident" caption="Title *" width="500" height="25" multiline="False" required="True" displayreadonly="False" /> <Comment id="201" width="500" name="Comment2" caption="* All messages are published with a short title that describes the feedback" multiline="True" height="40" /> <Comment id="202" height="20" name="c1" caption=" " /> <Combobox id="5" name="Unit" caption="Unit" width="500" type="12" required="True" displayreadonly="True"></Combobox> <Combobox id="6" name="Country" caption="Country" width="500" type="11" required="True" displayreadonly="True"></Combobox> <Textbox id="7" name="Office" caption="Office" height="50" width="500" multiline="True" displayreadonly="True" /> <Textbox id="8" name="Cause" caption="Cause" height="50" width="500" multiline="True" displayreadonly="True" /> <Textbox id="9" name="Action" caption="Recommended actions" height="50" width="500" multiline="True" displayreadonly="True" /> <Combobox id="10" name="Theme" caption="Theme" width="500" type="3" required="True" displayreadonly="True"></Combobox> <Header id="102" name="Time" caption="Date, Time and location" /> <Datetime id="11" name="Date" caption="Date" width="120" displayreadonly="True" /> <Textbox id="12" name="Time" caption="Time" width="120" displayreadonly="True" property="True" /> <Textbox id="13" name="Location" caption="Location" width="500" displayreadonly="True" /> <Header id="103" name="info" caption="Contact information" /> <Textbox id="14" name="Name" caption="Name" width="500" tag="user.name" displayreadonly="False" /> <Textbox id="15" name="E-Mail" caption="E-Mail" width="500" tag="user.e-mail" displayreadonly="False" /> <Textbox id="16" name="Registered date" visibility="Hidden" width="500" tag="system.date" displayreadonly="False" /> </Fields> </document> Я хочу, чтобы элементы в XML анализировались последовательно, т. Е. В порядке их появления в исходной строке. Но используя SimpleXMLElement и simplexml_load_string массивы похожих элементов:
object(SimpleXMLElement)[292] public '@attributes' => array 'id' => string '0' (length=1) 'name' => string 'RegSimple' (length=9) 'Version' => string '0.1' (length=3) public 'Description' => string ' Configuration document for simple registration of incidents. This document will contain both the fixed and the user-defined fields to show on the registration screen. ' (length=178) public 'Fields' => object(SimpleXMLElement)[293] public 'Textbox' => array 0 => object(SimpleXMLElement)[294] public '@attributes' => array 'id' => string '1' (length=1) 'name' => string 'IncidentID' (length=10) 'visibility' => string 'Hidden' (length=6) 'width' => string '500' (length=3) 'displayreadonly' => string 'False' (length=5) 1 => object(SimpleXMLElement)[298] public '@attributes' => array 'id' => string '3' (length=1) 'name' => string 'Description' (length=11) 'caption' => string 'My feedback' (length=11) 'width' => string '500' (length=3) 'height' => string '75' (length=2) 'multiline' => string 'True' (length=4) 'required' => string 'True' (length=4) 'displayreadonly' => string 'True' (length=4) 2 => object(SimpleXMLElement)[299] public '@attributes' => array 'id' => string '4' (length=1) 'name' => string 'Incident' (length=8) 'caption' => string 'Title *' (length=7) 'width' => string '500' (length=3) 'height' => string '25' (length=2) 'multiline' => string 'False' (length=5) 'required' => string 'True' (length=4) 'displayreadonly' => string 'False' (length=5) public 'Comment' => array 0 => object(SimpleXMLElement)[295] public '@attributes' => array 'id' => string '200' (length=3) 'height' => string '10' (length=2) 'name' => string 'c1' (length=2) 'caption' => string ' ' (length=1) 1 => object(SimpleXMLElement)[300] public '@attributes' => array 'id' => string '201' (length=3) 'width' => string '500' (length=3) 'name' => string 'Comment2' (length=8) 'caption' => string '* All messages are published with a short title that describes the feedback' (length=75) 'multiline' => string 'True' (length=4) 'height' => string '40' (length=2) 2 => object(SimpleXMLElement)[301] public '@attributes' => array 'id' => string '202' (length=3) 'height' => string '20' (length=2) 'name' => string 'c1' (length=2) 'caption' => string ' ' (length=1) public 'Header' => array 0 => object(SimpleXMLElement)[296] public '@attributes' => array 'id' => string '100' (length=3) 'name' => string 'Header' (length=6) 'caption' => string 'Description' (length=11) 1 => object(SimpleXMLElement)[308] public '@attributes' => array 'id' => string '102' (length=3) 'name' => string 'Time' (length=4) 'caption' => string 'Date, Time and location' (length=23) 2 => object(SimpleXMLElement)[312] public '@attributes' => array 'id' => string '103' (length=3) 'name' => string 'info' (length=4) 'caption' => string 'Contact information' (length=19) public 'Radiobox' => object(SimpleXMLElement)[297] public '@attributes' => array 'id' => string '2' (length=1) 'name' => string 'Type' (length=4) 'caption' => string 'Feedback type' (length=13) 'width' => string '500' (length=3) 'type' => string '19' (length=2) 'displayreadonly' => string 'true' (length=4) public 'Combobox' => array 0 => object(SimpleXMLElement)[302] public '@attributes' => array 'id' => string '5' (length=1) 'name' => string 'Unit' (length=4) 'caption' => string 'Unit' (length=4) 'width' => string '500' (length=3) 'type' => string '12' (length=2) 'required' => string 'True' (length=4) 'displayreadonly' => string 'True' (length=4) 1 => object(SimpleXMLElement)[303] public '@attributes' => array 'id' => string '6' (length=1) 'name' => string 'Country' (length=7) 'caption' => string 'Country' (length=7) 'width' => string '500' (length=3) 'type' => string '11' (length=2) 'required' => string 'True' (length=4) 'displayreadonly' => string 'True' (length=4)
В этом результате все элементы Textbox возвращаются в одном массиве. Аналогично, все комментарии и Comboboxes возвращаются в отдельных массивах независимо от порядка в исходном XML.
Может ли кто-нибудь сказать мне, как разбирать элементы в их фактическом порядке? Благодарю.
Вы можете использовать SimpleXmlIterator и RecursiveIteratorIterator для перемещения по дереву:
$tree = new RecursiveIteratorIterator( new SimpleXmlIterator($xml), RecursiveIteratorIterator::SELF_FIRST ); foreach ($tree as $node) { echo $node->getName(), PHP_EOL; }
выведет ( demo )
Description Fields Textbox Comment Header Radiobox Textbox Textbox Comment Comment Combobox Combobox Textbox Textbox Textbox Combobox Header Datetime Textbox Textbox Header Textbox Textbox Textbox
Вам нужно продолжать перемещаться по дереву элементов XML. Каждая ветка – еще один simple_xml_element, и вы ударяете их в ловушки foreach.
<?php /* For each <character> node, we echo a separate <name>. */ foreach ($xml as $element) { $elementName = $element->getName(); $elementAttributes = $element->attributes(); if ($element->children()) { foreach ($element->children() as $subElement) { // etc } } } ?>
