以下是源xml:xml
这是Adobe生成的fxg文件的xml。 FXG文档是有效的xml,它基本上包含可以编辑的文档的所有信息。此特定问题适用于可在FXG中更改的文本,以便内容可以更改。
我尝试使用xpath相对位置获取该元素中具有s7:elementID
属性的所有RichText元素和属性。
源XML只有三个RichText
个元素,其中只有两个元素具有s7:elementID
<?php
$url = "http://testvipd7.scene7.com/is/agm/papermusepress/HOL_12_F_green?&fmt=fxgraw";
$xml = simplexml_load_file($url);
$xml->registerXPathNamespace('default', 'http://ns.adobe.com/fxg/2008');
$xml->registerXPathNamespace('s7', 'http://ns.adobe.com/S7FXG/2008');
$textNode = $xml->xpath("//default:RichText/@s7:elementID");
print("<pre>".print_r($textNode,true)."</pre>");
?>
我在另一个问题的帮助下得到了这一点。但返回的数组并不是我所期待的。像我一样设置xpath,我希望它选择具有RichText
的所有s7:elementID
元素,以及该元素的其他属性。但是,它并没有抓住这些元素的任何其他属性。这是它输出的内容:
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[elementID] => smalltext
)
)
[1] => SimpleXMLElement Object
(
[@attributes] => Array
(
[elementID] => largetext
)
)
)
如果我采用完全相同的php但是像这样更改xpath:
$textNode = $xml->xpath("//default:RichText");
我得到这个数组结果:
Array
(
[0] => SimpleXMLElement Object
(
[@attributes] => Array
(
[x] => 278.418
[y] => 115.542
[columnGap] => 18
[columnCount] => 1

)
)
)
)
[1] => SimpleXMLElement Object

[trackingRight] => 4%

[height] => 29
)
[content] => SimpleXMLElement Object
(
[p] => SimpleXMLElement Object
(
[span] => THE JOHNSONS
)
)
)
[2] => SimpleXMLElement Object
(
[@attributes] => Array
(
[x] => 278.418
[y] => 77.2373
[columnGap] => 0
[columnCount] => 1
[textAlign] => left
[fontFamily] => Trade Gothic LT Pro Bold Cn
[fontSize] => 11
[color] => #518269
[whiteSpaceCollapse] => preserve
)
[content] => SimpleXMLElement Object
(
[p] => SimpleXMLElement Object
(
[span] => Array
(
[0] => W
[1] => ishing you the best this season.
)
)
)
)
)
如果您注意到,前两个数组项甚至没有s7:elementID
的信息,但它们应该是两个。第三个设计没有s7:elementID
。
任何人都可以解释为什么我会得到这些意外的数组结果,某些属性显示出来,而其他属性没有?
更新
Per dusan,我将php更新为:
$textNode = $xml->xpath("//default:RichText[@s7:elementID]");
现在,数组只返回没有前缀的元素的属性。我需要所有属性,前缀而不是。

更新2
将php更改为此似乎获取所有属性,包括默认属性和s7
前缀:
<?php
$url = "http://testvipd7.scene7.com/is/agm/papermusepress/HOL_12_F_green?&fmt=fxgraw";
$xml = simplexml_load_file($url);
$xml->registerXPathNamespace('default', 'http://ns.adobe.com/fxg/2008');
$xml->registerXPathNamespace('s7', 'http://ns.adobe.com/S7FXG/2008');
$textNode = $xml->xpath("//default:RichText[@s7:elementID]"); // //default:RichText[@s7:elementID]/@*
function pr($var) { print '<pre>'; print_r($var); print '</pre>'; }
foreach($textNode as $node){
pr($node->attributes('http://ns.adobe.com/S7FXG/2008'));
pr($node->attributes());
}
?>
XML结果:

现在它能够检索RichText
元素的所有属性。如何将某些属性存储为特定变量?例如,如何为s7:elementID
和fontSize
属性设置变量?
答案 0 :(得分:2)
使用//default:RichText/@s7:elementID
,您选择elementID
属性,而不是RichText
标记。
使用此:
$textNode = $xml->xpath("//default:RichText[@s7:elementID]");
更新 SimpleXMLElement::attributes docs说:
SimpleXML制定了向大多数方法添加迭代属性的规则。无法使用var_dump()或其他任何可以检查对象的内容来查看它们。
所以print_r
没有向您显示所有信息。尝试使用其命名空间获取属性:
foreach($textNode as $node){
var_dump($node->attributes('http://ns.adobe.com/S7FXG/2008'));
}
