How to check VARCHAR(n) for well-formed XML before CAST/CONVERT

由 ℡╲_俬逩灬. 提交于 2021-01-27 06:23:08
问题 My company has a logging table containing a VARCHAR(N) column in which a string is placed that is supposed to be XML, but as it turns out it is not always well-formed. In order to perform analysis on the logging (to identify error trends, etc.), I have been using a LIKE statement. However, this is remarkably slow. Recently, I discovered that SQL Server supports XQuery, so I started playing with it. The problem I'm running into is that I can't figure out a way to handle CAST/CONVERT errors

how to validate decimal numbers in PHP

Numeric strings consist of optional sign, any number of digits, optional decimal part and optional exponential part . Thus +0123.45e6 is a valid numeric value. Hexadecimal notation (0xFF) is allowed too but only without sign, decimal and exponential part. I don't want the exponent part or hexadecimal notation. The user will be
