Armstrong\u003c\/b\u003e (Author)\u003c\/p\u003e\u003cp\u003eLet me tell you a story.\u003cbr\u003e\u003cbr\u003eA year before this book came out, I had to query some XML in a SQL Server database. So I looked online and found a language called XPath. \u003cbr\u003e\u003cbr\u003eXPath was THE way to navigate XML documents. It was what SQL was to databases, what regex was to text. XPath would let me extract the data I needed, using one simple line of code. The only problem was, I couldn't get it to work.\u003cbr\u003e\u003cbr\u003eSo I started reading about XPath online. I tried out XPath expressions, just to figure out how the language worked. I copied working code posted online, ran it, and got back errors.\u003cbr\u003e\u003cbr\u003eIn the end, I learned that SQL Server supported XPath 1.0. I'd been trying to use features from version 2.0.\u003cbr\u003e\u003cbr\u003eTime passed. I forgot about XPath.\u003cbr\u003e\u003cbr\u003eThen I used a tool called Selenium to design automated website tests, and I ran into XPath again. This time, it was my only option for navigating to various parts of a web page. This time, it worked great. It navigated the Html perfectly, using a single-line expression each time.\u003cbr\u003e\u003cbr\u003eThis was a great tool. I wanted to master it. The problem was, there is a lot more to XPath than there seems. Also, the information I found online was hard to learn from. Often it was incomplete. The more complete sources were written as technical references, not for learners to work through. Some of what I found was misleading, and, sometimes, it was just wrong.\u003cbr\u003e\u003cbr\u003eSo, I experimented. I ran expressions. I read specifications. I read the specifications they cross-referenced. I took notes. In the end, I did it.\u003cbr\u003e\u003cbr\u003eAnd because I've written a few IT books before, I recorded all of these notes and experiments in an e-book format.\u003cbr\u003e\u003cbr\u003eThis is the result. It has everything I could think of to help someone master using XPath. It has practice exercises (based on downloadable XML files), so you can learn to use XPath, not just read about it. It has answers to those exercises. It has primers on XML and XML namespaces, so you can brush up on those first.\u003cbr\u003e\u003cbr\u003eIt's written as a course, so you can go from beginner, all the way to expert, as simply as possible.\u003cbr\u003e\u003cbr\u003eI hope you find it useful.\u003c\/p\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eNumber of Pages:\u003c\/strong\u003e 182\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003eDimensions:\u003c\/strong\u003e 0.39 x 9 x 6 IN\u003c\/div\u003e\n            \u003cdiv\u003e\n\u003cstrong\u003ePublication Date:\u003c\/strong\u003e January 26, 2020\u003c\/div\u003e\n            ","brand":"BooksCloud","offers":[{"title":"Default Title","offer_id":52493457916211,"sku":"9781675981504","price":39.38,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0300\/5595\/6612\/files\/TnVKVUpzK0JjL2NDNDZoMEk1MkdHUT09.webp?v=1759953538","url":"https:\/\/www.vysn.com\/en-ca\/products\/learn-xpath-fast-a-beginner-friendly-exercise-based-course-for-people-who-want-to-use-xpath-in-selenium-sql-server-xquery-or-anywhere-else-paperback","provider":"VYSN","version":"1.0","type":"link"}
