You can't really parse HTML with regular expressions. It's too complex. Regular expression won't handle <![CDATA[ sections and reference enities correctly at all.
I recommend Html Agility Pack
This is an agile HTML parser that builds a read/write DOM and supports plain XPATH or XSLT (you actually don't HAVE to understand XPATH nor XSLT to use it, don't worry...). It is a .NET code library that allows you to parse "out of the web" HTML files. The parser is very tolerant with "real world" malformed HTML. The object model is very similar to what proposes System.Xml, but for HTML documents (or streams).
How can I extract repeated paragraphs of data from an html document. Every paragrahp is preceded by the line:
<p><i>Summary as passed House:</i> <br>
You can obtain all Paragraph tags using the WebBrowser control using the following technique:
Dim oElements as HtmlElementCollection
oElements = WebBrowser1.Document.GetElementsByTagName("p")
For each oElement as HtmlElement in oElements
if oElement.InnerHtml.Contains("<i>Summary as passed House:</i>") then
You can parse the rest to get the specific data within the <P> tags
Hope this helps.
Hi. I have a form with list box : lst_product, datagridview : grd_order and button: btn_addline. lst_product has a list of product ids selected from database (MS Acess 2013) , grd_order is by default empty except for 2 headers and btn_addline adds rows to grd_order.
Hi, as I was told that my code doesn’t scale well at all, I thought perhaps I’d try to get a better understanding of interfaces/abstract classes and classes and the relationship between them.
I don’t want at this stage work on a big separate project as I've already got plenty ...
I am writing a java program that needs to execute shell commands, so I wrote a function that would take the command to execute as a string (ie: "mkdir ~/Folder1") and execute that command with the shell. Here is the function:
Runtime run = Runtime.getRuntime();
