XML to Objects in PHP 5.x eregi_replace vs preg_replace
Posted: Sat Feb 13, 2016 6:13 pm
Wow, so I just modified my XML reader and Object nesting creator from eregi_replace to preg_replace. It went from confusing to what the fuck am I doing to oh... this is much more logical and I can understand it.
I built my own CMS website skeletons like wordpress in a way. So, instead of always using MySQL for a db and tables, sometimes I take the route of text files sites.xml and interests.xml etc
At times, I might forget to add no more than one space, or tabs and newlines all over the place to make my code easier to understand. Well, when you parse, or mechanically read it, the computer goes nuts. 7 years ago I tackled making XML into an object so you could access it with arrows in a family tree in PHP
db-> sect-> (title | blurb | gallery | link)
db[0]->sect[0]->title[0]-DATA
would be the title from
<db>
<sect>
<title>the mummy</title>
</sect>
</db>
etc..
well, regular expression are NUTS! Especially the 40+ flavors where the rules are always all different. So, I tackled POSIX a long time ago, which is eregi_replace in PHP, and now a more logical and expressive version PCRE.
What once was
"find a greater than symbol >"
"find lots of space, tabs, or new lines"
"find a less than symbol <"
in POSIX was this:
$data=eregi_replace(">"."[[:space:]]+"."<","><",$data);
in PCRE is this:
$exp1='/(?<=>)\s+(?=<)/';
$data=preg_replace($exp1,'',$data);
and to then find "&" or "&" which are ampersands in two ways from a web server output, you could do this:
POSIX
$data=eregi_replace("&","##",$data);
PCRE
$data=html_entity_decode($data);
$exp2='/\&+/';
$data=preg_replace($exp2,'##',$data);
so now I can replace "&" and or "&" to just "&" inline with a cool "html_entity_decode" subrountine built into PHP
then I can find all "&" characters and replace them with '##' which I use to notate an ampersand just in case an xml field has & in it "LAW & ORDER" etc, looks like "LAW ## ORDER"
then when I spit it back into a DATA node I build in my nesting, I just tell it, hey replace it back from ## to &
POSIX
$data=eregi_replace("##","&",$data);
PCRE
$exp1='/(##)/i';
$data=preg_replace($exp1,'&',$data);

/*
XML_parse.php v3.0 generic xml parser to associate arrays ©2008,2016 by Kristoffe Brodeur. All Rights Reserved.
04-07-2008 COMPACT VERSION v1.0
08-24-2008 added CSS formatting and colored DIV alternations
08-28-2008 found a way to replace &->## and then ##->& so the PHP parser wouldn't freak out for HTML links with variables
02-16-2009 made XML_parse.php it's own file to be included in other php files by include 'XML_parse.php';
02-23-2009 added __contruct php5 class model changes
07-01-2009 made all calls have proper amounts of arguments
07-14-2009 found that if(!tgtPar->{$sName}) throws an error but if(!isset(tgtPar->{$sName}) does not, thus the apache error.log fills up slower!
02-13-2016 preg_replace is depreciated, so now preg_replace is used.
reformatted code layout
/(?<=>)\s+(?=<)/ replace all >..~..< with space(s) in-between with just >< by selecting inside > and < and giving '' nothing
html_entity_decode change all forms of "&" or "&" with "&"
'/\&+/ replace all "&" with "##" for coding and non collision with xml
/(##)/i inline into an object oriented format, replace all "##" with "&"

<title>Vox Inc.Design Consortium</title>
<blurb>This multimedia website has a custom designed PHP GD2 drop down menu system. The client wanted to have a transparent custom TTF typeface and animate it, but not rely entirely on flash. The menu system was broken into segments, and a dynamic backend renderer was created for the menu system to make transparent PNG files rendered via GD2, which can change anytime the client modifies the areas in the backend. There is jQuery, JS, PHP and AS2 all working together to get the custom look they required.</blurb>
