php-使用XMLWriter生成XML文件
我正试图通过以下循环创建一个包含人员及其子女姓名的XML文件:php-使用XMLWriter生成XML文件,php,xml,xmlwriter,Php,Xml,Xmlwriter,我正试图通过以下循环创建一个包含人员及其子女姓名的XML文件: $xml_file = new XMLWriter(); $xml_file->startElement("People"); while ($list_of_people->current != NULL ){ $xml_file->writeElement("Person"); // create a new person $xml_file->startElement('Pers
$xml_file = new XMLWriter();
$xml_file->startElement("People");
while ($list_of_people->current != NULL ){
$xml_file->writeElement("Person"); // create a new person
$xml_file->startElement('Person');
$xml_file->writeAttribute('name', $list_of_people->current->name); // add their name as an attribute
if ($list_of_people->current->children != NULL){
while ($list_of_people->current->child_current != NULL){ // if they have children create them as well
$xml_file->writeElement("Person");
$list_of_people->startElement('Person');
$xml_file->writeAttribute('name', $list_of_people->current->child_current->child_name);
$xml_file->endElement();
$list_of_people->current->child_current = $list_of_people->current->child_current->next;
}
}
$xml_file->endElement();
$list_of_people->current = $list_of_people->current->next;
}
正如您所看到的,在输出文件中,我应该有多个名为“Person”的元素,这取决于列表中有多少人以及他们中有多少人有孩子
我希望最终的XML文档是这样的一个示例:
<People>
<Person name="Anna"></Person>
<Person name="Joe">
<Person name="Willy"></Person> // Joe has a child named Willy
</Person>
<Person name="Rob"></Person>
</People>
//乔有一个孩子叫威利
现在,我关心的是,我如何知道$xml_file->startElement('Person');选择了我刚刚创建的当前人员,而不是之前已创建的任何人员元素,因为它们的名称相同
如果最终XML文件的各个元素具有相同的名称,如何访问它们
最后,我想保存这个XML文档并将其内容打印到stdout
谢谢 startElement方法不会选择当前人员,而是启动另一个人。事实上,您可以使用writeElement或startElement添加元素,但不必同时使用这两种元素 请参见此示例:
<?php
$people = array(
array('name' => 'Anne', 'children' => array()),
array('name' => 'Joe', 'children' => array(array('name' => 'Willy')))
);
//create a new xmlwriter object
$xml = new XMLWriter();
// Used to write to xml file - uncomment the next line to print xml to a file
// $xml->openURI('people_test.xml');
// used for string output from memory
$xml->openMemory(); // comment this line to print xml to a file
//set the indentation to true
$xml->setIndent(true);
//create the document tag
$xml->startDocument();
$xml->startElement("People"); // start People
foreach($people as $person) {
$xml->startElement("Person"); // start Person
$xml->writeAttribute('name', $person['name']);
if(!empty($person['children'])) {
foreach($person['children'] as $child) {
$xml->startElement("Person"); // start Person
$xml->writeAttribute('name', $child['name']);
$xml->endElement();
}
}
$xml->endElement(); //End Personn
}
$xml->endElement(); //End People
// Display thue current buffer
echo $xml->flush();
?>

谢谢你发这篇文章!我现在明白多了:)然而,我这里有一个问题。生成的子项不是以“Person”标记结尾,而是如下所示:即使在内部循环中调用了endElement函数。Il也应该是相同的。看:谢谢你的帖子!我现在明白多了:)然而,我这里有一个问题。生成的子项不是以“Person”标记结尾,而是如下所示:即使在内部循环中调用了endElement函数。Il也应该是相同的。见:
