How do I replace this line ?

[jeddiki]

Hi,

I have some data in a flat file called test_file.xml
that reads:

<?xml version="1.0" encoding="utf-8"?><marketplace xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.click2sell.eu/marketplace.xsd"><product>

And I want to change it so that it reads :

<?xml version="1.0" encoding="utf-8"?><marketplace><product>

What is the best way to do this ?

I assume I should open the file and get the contents:

$file_in = 'test_file.xml';
$source = file_get_contents( $file_in  );

Now should ıs use preg_match()

or would str_replace()

E.g can I have "wild characters" in the str_replace() ?

$source= str_replace('<marketplace xmlns*' , '<marketplace>', $source);

// Write it to out file
file_put_contents( $file_out, $source );

Maybe I need to use preg_match()
to do this, or preg_replace() ??

Any advice, much appreciated :)

As far as I know str_replace does not accept wildcards

1. If you're comfortable with regular expressions preg_replace should do it.. basically you'd be looking for <marketplace<sp ace>*>

2. you could parse it using php built-in xml parser functions. If element marketplace is found and it has attributes, you would replace that with a <marketplace> element without attributes.

info about xml parser is found here: http://www.php.net/manual/en/function.xml-parse.php

You could go through the file line by line and when condition is not met you just feed the original line and when one is found you do a replace.

3. Go through the document programmaticall y searching each line for
<marketplace<sp ace>. When found, search for > ignore that part and insert the rest of the line. This is not all that time efficient but might be fun

I would definetley go with option one though as the coding required would be significantly less. Also the regexp required is not complicated so it should be quite efficient.

preg_replace() is overkill if you know what the string is that you need to replace.

$str = str_replace("<marketplace xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:noNamespaceSchemaLocation="http://www.click2sell.eu/marketplace.xsd">", "<marketplace>", $str);

Thanks for reply,

I should have said - there is only one place where this occurs and it is right at the top of the file.

So is this what I need : ?

$file_in = 'test_file.xml';
$file_out = 'test_output.xml';

$source = file_get_contents( $file_in  );
$source = preg_replace( '#\<marketplace *\>#', '<marketplace>', $source);

 // Write it to out file
file_put_contents( $file_out, $source );

Hi Markus,

I am a bit concerned about that being so specific.

If they change the file schema name, it won't work.

I would recommend loading this up in a XML parser. It's less risk of accidentally messing up the markup.

Try using the DomElement::rem oveAttribute method, or something like that.
