How to iterate/parse all children for given tag

[pkasson]

Hi,

I have tried various xpath expressions to get all images, within lists, divs, etc. But, not all images (or script tags) are found.

Not sure if its an xpath issue, but how can the entire tree be iterated through, searching for these tags ... while it may be slower, brute force sometimes works.

Thanks,

Peter

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];
