Re: etc_query: all things Textpattern

Thanks Oleg, my mistake!

But I still can not get the data from fields like {swell/minBreakingHeight?} e.g., from the specific timestamp. I try this query:

query="//localTimestamp[. ='1376784000']"/*

But it does not work, obviously.

Re: etc_query: all things Textpattern

Yes, because swell is a sibling of localTimestamp, not its child. Try

query="//localTimestamp[.='1376784000']/following-sibling::swell/minBreakingHeight"

if you wan just this data, or

query="//localTimestamp[.='1376784000']/.."

to match the parent of the desired timestamp, then {swell/minBreakingHeight?} and other selectors inside etc_query.

Re: etc_query: all things Textpattern

Oleg, sorry for being such a pain in the ass, but it would be possible to replace the datestamp in the query for the current datestamp using something like this?

<txp:php>
        $now = time();
        $date = date('m/d/Y H', $now) . ':00';
        $currenttime = strtotime($date);       
</txp:php>

then

query="//localTimestamp[. =misterious code $currenttime]/.."

Re: etc_query: all things Textpattern

Sure, the usual parsing rules apply, just mind the quotes. You can even do it etc_query-way, calling query="//localTimestamp[.='{?||strftime(%F %H:00).strtotime}']/..". However, there is no guarantee that this timestamp will be present in the feed. Edit: you can use query="//localTimestamp[.>='{?||strftime(%F %H:00).strtotime}']/.." to find the immediate successor of the current timestamp.

Re: etc_query: all things Textpattern

Hi Oleg.
If you have time (and inclination), I’d appreciate a pointer on where I’m going wrong with the following. I want to query and display database contents, specifically the ip field of txp_discuss with a provided discussid. My SQL syntax is correct, I think, but this isn’t outputting anything when used in a comment form:

<txp:etc_query data="SELECT ip FROM txp_discuss WHERE discussid = <txp:comment_id />">{ip?}</txp:etc_query>

Thank you in advance.

Re: etc_query: all things Textpattern

Hi Pete, I think that’s just double quotes:

<txp:etc_query data='SELECT ip FROM txp_discuss WHERE discussid = <txp:comment_id />'>{ip?}</txp:etc_query>

or even

<txp:etc_query data='SELECT ip FROM txp_discuss WHERE discussid = <txp:comment_id />' />

should be ok.

Re: etc_query: all things Textpattern

Version 1.2.7: minor update to enable LDAP queries (data is composed of ;-separated rdn, filter and only fields):

<txp:etc_query markup="ldap" url="ldaps://my.ldap.server:636" data="ou=people,dc=org; uid=ol*; uid,sn" query="count" />

Works for me, but testers are more than welcome.

Edit: also tightened the security a little bit: only privileged users can import data from url or databases.

Re: etc_query: all things Textpattern

Version 1.2.8: few changes inspired by this thread:

  • new save attribute, allowing to save the imported and transformed dom tree, that can be quickly reused later with markup="data";
  • new {!variable} pattern, that will be actualized on each call, and not only once like {?variable} pattern;
  • new {##} pattern for internal nodelist number;
  • more secure: requires php privileges for all advanced operations.

Re: etc_query: all things Textpattern

Here’s one. I want to reformat a mail chimp archive called on a page with javacript… it looks like this…

document.write("<div class=\"display_archive\"><div class=\"campaign\">09\/19\/2013 - <a href=\"http:\/\/us7.campaign-archive1.com\/?u=999&id=888\" title=\"Title 1\" target=\"_blank\">Title 1<\/a><\/div><div class=\"campaign\">09\/12\/2013 - <a href=\"http:\/\/us7.campaign-archive1.com\/?u=777&id=666\" title=\"Title 2\" target=\"_blank\">Title 2<\/a><\/div><\/div>");

So obviously I point the query field at the url of the script, but in order to process this properly I need to do two things first:

  1. strip escape characters
  2. remove document.write(" and "0;

At that point I’m confident that I can do the reformatting I need.

Re: etc_query: all things Textpattern

Hi Dale,

if you import this script from external url and are quite sure about its structure, try this:

<!-- save the script in "some_script" variable -->
<txp:etc_query url="script_url" markup="raw" name="some_script" />

<!-- now clean up and query -->
<txp:etc_query data="{?some_script||trim.preg_replace(/^document\.write\(|\);$/i,,$)}" argsep="," markup="json" />

If it is inside the page itself, you can go the same “save then transform” way, but the optimal solution depends on how many they are, and what has to be extracted.
