Is there any difference between these two methods of writing scraper?

Code:

<RegExp input="$$7" output="\1" dest="5+">
                <RegExp input="$$6" output="&lt;credits&gt;\1&lt;/credits&gt;" dest="7">
                    <RegExp input="$$1" output="\1" dest="6">
                        <expression noclean="1">scenariusz:(.*?)&lt;/ul&gt;</expression>
                    </RegExp>
                    <expression repeat="yes" fixchars="1">title=[^&gt;]+&gt;([^&lt;]+)&lt;</expression>
                </RegExp>
                <expression noclean="1" />
            </RegExp>

Code:

<RegExp input="$$1" output="\1" dest="6">
                <expression noclean="1">scenariusz:(.*?)&lt;/ul&gt;</expression>
            </RegExp>
            <RegExp input="$$6" output="&lt;credits&gt;\1&lt;/credits&gt;" dest="7">
                <expression repeat="yes" fixchars="1">title=[^&gt;]+&gt;([^&lt;]+)&lt;</expression>
            </RegExp>
            <RegExp input="$$7" output="\1" dest="5+">
                <expression noclean="1" />
            </RegExp>

I can not understand the difference. The second way is to me more readable.
