[英]PHP - Two same nodes in xml
I have the following code: 我有以下代码:
<?php
$str = '<?xml version="1.0" encoding="utf-8"?>
<ROOT>
<ITEM>
<TITLE>Title1</TITLE>
<CATEGORY>Books</CATEGORY>
<CATEGORY>Books | Novel</CATEGORY>
</ITEM>
<ITEM>
<TITLE>Title2</TITLE>
<CATEGORY>Books</CATEGORY>
<CATEGORY>Books | Sci-fi</CATEGORY>
</ITEM>
</ROOT>';
$xml = simplexml_load_string($str);
$s_xml = $xml->xpath("/ROOT/ITEM");
foreach($s_xml as $s_cat){
$cat_group = htmlspecialchars($s_cat->CATEGORY);
echo $cat_group."<BR />";
}
?>
I can't edit the XML so I need to solve the folowing problem. 我无法编辑XML,因此需要解决以下问题。 How to say to PHP that I need to show the second node called CATEGORY and not the first one.
怎么说PHP,我需要显示第二个名为CATEGORY的节点,而不是第一个。 In my example I have the output
在我的示例中,我有输出
Books
Books
And I need: 我需要:
Books | Novel
Books | Sci-fi
Thank you! 谢谢!
This is what you are looking for (note the [1]): 这是您要寻找的(请注意[1]):
$cat_group = htmlspecialchars($s_cat->CATEGORY[1]);
It takes the second item in the array of category elements 它需要类别元素数组中的第二项
You can always look at your elements like this, to figure out how the structure looks: 您总是可以这样看待您的元素,以弄清楚结构的外观:
print_r($s_cat->CATEGORY);
