With this one, seemingly minor change to the headers, this code suddenly won't work, even if I make the appropriate modifications to the header criteria. Say that, rather than those columns being labeled 'Character' and 'Entity' they were and, respectively. However, if the header I'm looking for is an image (usually of stylized text stating what the columns represent), this ceases to work. Thanks to HTML::TableExtract's headers method, this is quite simple: My goal is to extract the data from a table (for this example we'll use this one), where I know only the headers for the fields. Let's try this again, this time fueled by a bit more sleep. I should have known better than to create a root node that only contained one line of actual perl code.

sooper :) That's the preferred way, probably, but I suspect you're parsing someone else's web pages, so I guess it's probably not possible.

Or, if you're dealing with XHTML, you could parse it using an XML::Parser, and then use XML::XPath to generate a query which would automatically find your answer! (Check out XPath if you haven't before - you can search through parsed XML trees for tags based on their name, their text content, their attributes, their lineage, etc. Probably the best way will be to write your own parser in HTML::Parser, or (better) extend HTML::TableExtract to make it possible to use 'nodes' (the tags :) and their attributes within the evaluation. This is obvious, because is an empty tag - in X/HTML, it would be written, making it plain it contains no text nodes. Now, by my understanding, you're trying to pick out a table with a tag in the tag? I've never tried this myself, but it's quite possible that it's only evaluating text nodes - that is, the tag is markup, not content, even if it has attributes. If I haven't, try to rephrase - with examples, if possible. Re: using the headers method of HTML::TableExtract to find an imageįorgive me, but I'm not exactly sure if I understand your question. Am I approaching this the right way? Do I need to 'textify' HTML::Parser objects to make HTML::TableExtract search for the image's url, or can all this be done interfacing only with TableExtract? Is there some better way to extract the data from an HTML table when using an image as an anchor point?Īnd no, I don't own 2 7 pairs of sweatpants.

However, I can't figure out how to do this with HTML::Parser. If I were dealing with HTML::TokeParser I'd work around this with a line like this: I assume that the source of the problem lies in the fact that, as TableExtract is a subclass of HTML::Parser, it's no longer seeing the url for the image as text that it should be parsing. For most of the data this only takes a few lines, but for some reason I can't make it search for a header when that header consists only of an image (for which I know the URL). I'm wanting to parse the content out of an html table using HTML::TableExtract. Brainpan emerges from the shadows of the monastery and humbly seeks enlightenment from his elders.
