Parser. How to implement?

Question

PHP

Good day! Please tell me how you can implement a parser with the following logic
. There are a bunch of files with names like abc.htm abc1.htm in the files there is a question and an answer, respectively, you need to parse the content from these files and write Bitrix to the infoblock element. Here are the results pastebin.com/p3Wi4vzC. The problem is that only one property is written. Thoughts on this are as follows. you need to take a file with the name abc, parse it (this is done), then add 1 to the name and search for a file with the name abc1, if found, then parse, if not, do nothing and write it to the info block, and so on

Answer 1

well, apparently the condition is not met if (is_readable($name."1"))
Either PROPERTY_VALUES cannot parse arrays but only strings
Show the code that you have with the $el->Add method
