How to iterate/parse all children for given tag about hpple

Can you show me your code?

The code I used earlier is below. In the interim, I just iterated through the whole tree, looking for child tags that matched what I wanted (brute force). While not elegant, it worked.

This is re-used in a method, passing in various tags, like "script" or "img"

NSArray * elements = [doc searchWithXPathQuery:[@"//" stringByAppendingFormat:@"%@", tagName]];

Clearly, not the most exhaustive REGEX expression, so I tried this as wellL

NSArray *imageTags = [NSArray arrayWithObjects:@"img", @"ul/li/img", @"ul/img", @"div/img", @"li/img", @"a/img", nil];

and iterated through these variations to determine if more hits were found.

Lastly, tried direct REGEX interaction with this

NSString *REGEX_IMG_CONTENT = @"<img[^>]+src="([^\">]+)"";

(the regex is not playing nice with web editor - < img [ ^ > ] + src ...

[self search:doc withRegexString:REGEX_IMG_CONTENT];
