Querying HTML with LINQ to XML

by Beth Massi via Beth Massi on 4/25/2008 11:00:28 PM

Often times we need to parse HTML for data. Sure in a perfect world everything would have a nice service or API wrapped around it but as we all know this is not always the case. Many times we're left with parsing files or "screen scraping" to get the data we need from other applications. Sure this is brittle, but sometimes it's the best we can do. And sometimes you're just trying to get the data once so "good enough" is really good enough. I was faced with that challenge myself this week. Yes ... [ read more ] 11 comment(s)

VB XML Cookbook, Recipe 3: Identity Transforms (Doug Rothaus)

by VBTeam via The Visual Basic Team on 4/25/2008 6:19:00 PM

An identity transform in XSLT does just what the name implies: replace the identity of an element or attribute with a new identity. Identity transforms are especially critical when dealing with XML markup that is less rigid in its structure. Consider a documentation structure for news articles. Whenever a title is referred to within an article, it is highlighted with italics. However, the XML schema for the article does not specify italics, it specifies that the term is some type of title so t ... [ read more ] 2 comment(s)

Generating proxies with Astoria's WebDataGen under Vista UAC

by Julie Lerman via Julie Lerman on 4/25/2008 2:55:09 AM

This bit me in the butt ... TWICE! When using WebDataGen so that you can get a proxy class for an Astoria data service, if you are running under UAC, the output file will NOT get created, however the tool reports that the file was created successfully. I spent a lot of time trying to find the file or figure out what I was doing wrong. Then a week later, when it was late at night and I was sick so my brain was a little foggy, I had to create another proxy but totally forgot the pain ... [ read more ]

by V. Neil Knobbe via VB & .NET Blogs @ vbCity.com on 4/25/2008 2:17:00 AM

Ok, let’s call this page 22,492 in the book of things I did not know about Visual Studio 2005. I was reading something the other day, if I can remember or find it I will post up a link, and was surprised that I had missed this little bit before. (I have recently been reading “WPF for those who know Windows Forms” that can be found here and watching webcasts by William Steele on his WPF Soup To Nuts series so it could have could have come ...
