Title: 7 questions Last modified: August 31, 2016 --- # 7 questions * [NanoWisdoms](https://wordpress.org/support/users/nanowisdoms/) * (@nanowisdoms) * [10 years, 3 months ago](https://wordpress.org/support/topic/6-questions/) * 1) I have the following HTML in a post: * `` * I can use the ginner to get “December 22, 2015” but that is not what I want. I want to get the value of the attribute datetime. I would like to get “2015- 12-22T23:52:37+00:00”. How can I get this, i.e. get an attribute’s value? * If I could use regular expressions in the replace function then I could get it very easily like this: * `replace|{line}|| $1|` * Please consider allowing regular expressions in the replace. It would be ***very, very*** useful and powerful. * 2) In WordPress.com RSS feeds, they do not use but include the WordPress categories and tags assigned to a post. Both are coded as: * `` * Is there anyway to get ‘` from the RSS feed? * Then once I have that, if I could use regular expressions in the HTML parser replace function I could extract “… category name goes here …” very easily, like this: * replace|{line}||$1| * 3) I’m still confused about the meta processor. Can you give an example of how it is used and explain exactly what information it used for? * 4) Also for the metakey destination. Can you give an example of where its information goes in the post? * 5) I still don’t understand, what is “fix time”. I read the documentation here: [https://docs.google.com/document/d/1DOwgYcMJnzFdybhQN7n1CdZVK1bSa2ZHqbO1CumpjUs/edit?pref=2&pli=1#](https://docs.google.com/document/d/1DOwgYcMJnzFdybhQN7n1CdZVK1bSa2ZHqbO1CumpjUs/edit?pref=2&pli=1#) * And it says: * “This Option will set a lag time between time article being published in the source and the time outputted by obGrabber RSS Reader Engine. By default it is set to -24, meaning the outputted time will be 24 hours earlier than the publish time of your original article.” * But I don’t understand what this means. Can you give an exact example with times. * 6) Also can you explain the cache? It is unclear what is being cached and where? * * Thx * [https://wordpress.org/plugins/wp-pipes/](https://wordpress.org/plugins/wp-pipes/) Viewing 4 replies - 1 through 4 (of 4 total) * Plugin Contributor [Tung Pham](https://wordpress.org/support/users/phamtungpth/) * (@phamtungpth) * [10 years, 3 months ago](https://wordpress.org/support/topic/6-questions/#post-6963247) * Hi Nanowisdoms, * You bought HTML Parser processor, didn’t you?

Are they not accurate or have the wrong time zone? * Thread Starter [NanoWisdoms](https://wordpress.org/support/users/nanowisdoms/) * (@nanowisdoms) * [10 years, 3 months ago](https://wordpress.org/support/topic/6-questions/#post-6963292) * REPOST OF ORIGINAL FOR REFERENCE BECAUSE ORIGINAL DID NOT FORMAT CORRECTLY * DO NOT REPLY!!! ———————- 1) I have the following HTML in a post: * `` * I can use the ginner to get “December 22, 2015” but that is not what I want.
