Перейти непосредственно к simplexmlelement без xpath php
Все еще очень плохо знаком с php... У меня есть большая строка simplexml, и я хочу получить все фамилии из файла и в какой статье они где:
что-то вроде:
номер статьи 0 позиция автора 0 'van Tricht'
статья № 0 автор позиция 1 'Неман'
статья № 0 авторская позиция 2 'ван Трихт'
статья № 0 авторская позиция 3 'Бур'
.....
статья № 1 позиция автора 0 'van Tricht'
статья № 1 автор позиции 1 "Неман"
статья № 1 авторская позиция 2 'ван Трихт'
статья № 1 авторская позиция 3 'Бур'
Я хочу пойти прямо к Author->LastName но без использования xpath я попробовал это с xpath, но затем мои циклы foreach дают странные результаты... вот что я попробовал:
<?php
$i = 0;
$j = 0;
foreach ($xml->xpath('//AuthorList') as $AuthorList) {
$i ++;
$j = 0;
foreach ($xml->xpath('//Author') as $Author) {
$j ++;
echo $i . "articlenumber " . "author position" . $AuthorList->Author->LastName;
}
}
?>
Это строка XML:

[AbstractText] => Abnormalities in eye tracking are consistently observed in schizophrenia patients and their relatives and have been proposed as an endophenotype of the disease. The aim of this study was to investigate the performance of patients at Ultra High Risk (UHR) for developing psychosis on a task of smooth pursuit eye movement (SPEM). Forty-six UHR patients and twenty-eight age and education matched controls were assessed with a task of SPEM and psychiatric questionnaires. Our results showed that both the corrective and non-corrective saccadic rates during pursuit were higher in the UHR group. There were however no differences in smooth pursuit gain between the two groups. The saccadic rate was related to positive UHR symptoms. Our findings indicate that abnormalities in SPEM are already present in UHR patients, prior to a first psychotic episode. These abnormalities occur only in the saccadic system.

Чтобы получить желаемый результат, ваш цикл должен выглядеть так:
$i = 0;
foreach ($xml->xpath('//AuthorList') as $AuthorList) {
$j = 0;
foreach ($AuthorList->Author as $Author) {
echo join(' ', array('article number', $i, 'author position', $j, $Author->LastName));
$j++;
}
$i++;
}
