PHP通过xml读取带有特殊字符的链接

Question

I have an xml file that is editable via a webpage where users enter links. This looks like

 <links>
    <link1 path="http://abc.def.com/abcd?id=2&ed=4" > </link1>
 <links>

I read this xml via php and then add a button which will link here. What I'm currently doing is use a str_replace('&', '&',) on the xml string and then a str_replace('&', '&',) on the extracted path. Is there a more elegant way to do this?

Answer 1

What you have shown is not an XML file. An XML file cannot contain an unescaped ampersand.

The URL as stored in the XML should encode ampersand as &. When you read the XML file the XML parser will present you with the unescaped text, that is &. Of course, if you try to read the XML file without doing proper XML parsing, you will be in a mess, as you deserve to be.
