Tinymce editor gallery plugin Regexp problem? - regex

Question

I am using tinymce editor for inserting contents to mysql.
I have changed wordpress gallery editor plugin according to my system.
If there is gallery code in content. I convert this code to a symbolic photo, so that user understand there is a gallery , in stead of seeing a code. Like wordpress does.
If there is only 1 gallery in content, i convert this code to image successfully, but if there is more than 1 gallery it fails.
How can i convert all {gallery} code into a symbolic image before saving to db and convert these photos back to {gallery} code again while inserting or updating into mysql.
I am so bad on regular expression.
I think do_gallery RegExp has mistake. How should i change this.
initalising editor like:
ed.onBeforeSetContent.add(function(ed, o) {
ed.dom.loadCSS(url + "/css/gallery.css");
o.content = t._do_gallery(o.content);
});
ed.onPostProcess.add(function(ed, o) {
if (o.get)
o.content = t._get_gallery(o.content);
});
My "do and get gallery" codes like that:
_do_gallery : function(co) {
return co.replace(/\{gallery([^\]]*)\}/g, function(a,b){
var image = '<img src="gallery.gif" class="wpGallery mceItem" title="gallery'+tinymce.DOM.encode(b)+'" />';
console.log(image);
return image;
});
},
_get_gallery : function(co) {
function getAttr(s, n) {
n = new RegExp(n + '="([^"]+)"', 'g').exec(s);
return n ? tinymce.DOM.decode(n[1]) : '';
};
return co.replace(/(?:<p{^>}*>)*(<img[^>]+>)(?:<\/p>)*/g, function(a,im) {
var cls = getAttr(im, 'class');
if ( cls.indexOf('wpGallery') != -1 )
return '<p>{'+tinymce.trim(getAttr(im, 'title'))+'}</p>';
return a;
});
}
If Content is:
<p>Blah</p>
<p>{gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p>
<p>test</p>
this is ok
<img src="gallery.gif" class="wpGallery mceItem" title="gallery Name="tekne1" id="82" galeryID="15" sizeId="6" galery_type="liste"" />
But, if content is:
<p>Blah</p>
<p>{gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p>
<p>test</p>
<p>{gallery Name="gallery2" id="88" galeryID="11" sizeId="1" galery_type="slide"}</p>
<p>test2</p>
it logs
<img src="gallery.gif" class="wpGallery mceItem" title="gallery Name="gallery1" id="82" galeryID="15" sizeId="6" galery_type="list"}</p> <p>test</p> <p>{gallery Name="gallery2" id="88" galeryID="11" sizeId="1" galery_type="slide"" />
I hope i could explain my problem
Thank you.

I suspect that your original regex is a typo, looks like a missing Shift when you hit the ]. Try this:
/\{gallery([^\}]*)\}/g
Then the ([^\}]*) part will (greedily) eat up any sequence of characters that aren't }; your original one would consume any sequence of character that didn't include a ] and the result is that you'd grab everything between the first { and the last } rather than just grabbing the text between pairs of braces.
