Hyphens in XML attribute Name

[SeanF]

Hi:

I am trying to parse an SVG file in PHP by using SimpleXML. (Basically, I want to parse the SVG code, manipulate some elements to change color and write the new values back to the file.

I am able to read the file successfully and I am able to read the elements and the @attributes, so I think I'm on the right track.

The problem I am having is that some of the attribute elements have a hyphen (-) in their names and my code does not like that. I have tried various combinations of quotes and escaping the character but I am still getting errors.

The original SVG code looks like this:

 <g class="layer">
 <title>Layer 1</title>
 <image height="1735" id="Background" width="1071" x="0" xlink:href="data:img/png;base645ErkJggg==" y="-2"/>
 <rect fill="#d6d6d1" height="43" id="B709" width="43" x="771.5" y="125.5"/>
 <text class="cls-1" data-name="P 709 " fill="black" id="P_709_" x="791.559" y="142.076">
 <tspan id="svg_11" x="791.559">P</tspan>
 <tspan class="cls-2" dy="20.167" id="svg_12" x="791.559">709</tspan>
 </text>
 <rect fill="#d6d6d2" height="43" id="B710" width="43" x="816.5" y="126.5"/>
 <rect fill="#d6d6d3" height="43" id="B700" width="43" x="363.5" y="125.5"/>

I read the file using :

$xml = simplexml_load_file($file) or die("Can't read the AML data");

Checking what I have, I use:

print_r($xml);

A sample of what is returned is:

[rect] => Array ( 
[0] => SimpleXMLElement Object ([@attributes] => Array ( [fill] => #d6d6d6 [height] => 43 [id] => B709 [width] => 43 [x] => 771.5 [y] => 125.5 ) ) 
[1] => SimpleXMLElement Object ( [@attributes] => Array ( [fill] => #d6d6d6 [height] => 43 [id] => B710 [width] => 43 [x] => 816.5 [y] => 126.5 ) ) 
[2] => SimpleXMLElement Object ( [@attributes] => Array ( [fill] => #d6d6d6 [height] => 43 [id] => B700 [width] => 43 [x] => 363.5 [y] => 125.5 ) ) 
[3] => SimpleXMLElement Object ( [@attributes] => Array ( [fill] => #d6d6d6 [height] => 43 [id] => B703 [width] => 43 [x] ) 
[text] => Array ( 
[0] => SimpleXMLElement Object ( [@attributes] => Array ( [class] => cls-1 [data-name] => P 709 [fill] => black [id] => P_709_ [x] => 791.559 [y] => 142.076 ) [tspan] => Array ( [0] => P [1] => 709 ) ) 
[1] => SimpleXMLElement Object ( [@attributes] => Array ( [class] => cls-1 [data-name] => P 700 [fill] => black [id] => P_700_ [x] => 383.971 [y] => 142.494 ) [tspan] => Array ( [0] => P [1] => 700 ) ) 
[2] => SimpleXMLElement Object ( [@attributes] => Array ( [class] => cls-1 [data-name] => P 703 [fill] => black [id] => P_703_ [x] => 519.945 [y] => 142.084 ) [tspan] => Array ( [0] => P [1] => 703 ) ) 
) 

The problem I am having is the "data-name" attribute.

I am trying to assign it to a variable name using:

$dataname = $text->attributes()->data-name;

But it keeps failing.

Can someone suggest a solution? (or maybe there's an easier way to programmatically manipulate the SVG file?)

I am trying to assign it to a variable name using:

$dataname = $text->attributes()->data-name;

i'm not a PHP expert but i would try using quoting like this:

$dataname = $text->attributes()->"data-name";

Try

$dataname = $text->attributes()->{'data-name'};
