Question

我有以下XML代码：

<w:footerReference w:type="default" r:id="rId6"/>

在PHP中，我有以下代码：

// $footer is a SimpleXMLElement, contain the code above

foreach ($footer->attributes() as $attr_name => $attr_value) {
    dd($attr_name." = ".$attr_value);
}

foreach没有运行。

我也尝试过：

$type = 'type';
$footer->attributes()->$type; // empty string

$wtype = 'w:type';
$footer->attributes()->$wtype; // empty string

我当然可以将XML转换为字符串并执行一些正则表达式魔术，但是我认为这不是一个好方法。

更新：

这是整个XML文档代码：

如何访问w:type和r:id属性值？

Answer 1

您必须将属性名称空间作为attributes的参数传递

$type = $footer->attributes("http://schemas.openxmlformats.org/wordprocessingml/2006/main")->type;

$id = $footer->attributes("http://schemas.openxmlformats.org/officeDocument/2006/relationships")->id;

与foreach相同

foreach ($footer->attributes("http://schemas.openxmlformats.org/wordprocessingml/2006/main") as $attr_name => $attr_value) {
    dd($attr_name." = ".$attr_value);
}
foreach ($footer->attributes("http://schemas.openxmlformats.org/officeDocument/2006/relationships") as $attr_name => $attr_value) {
    dd($attr_name." = ".$attr_value);
}
