Good Lord. I just got my own email, and I apologize for the sea of code. Apparently, my email client sucks. Email me directly if you want a text file with code that is actually formatted. -Karl.

trouble destructing xml
by jeff＠ayendesigns.com 25 Mar '11

25 Mar '11

When all else fails, and #xml, ##php and #drupal-support come up empty...ask the folks who actually code :) I have an xml structure that has <this> <that parm1="a" parm2="b" parm3="c">red</that> <that parm1="e" parm2="f" parm3="d">blue</that> </this> I've tried simplexml and a few third-party scripts, one that loads the xml into an associative array rather than an object, and nothing lets me get at 'red' or 'blue'. When I use dsm() on the results, for example, in the case of the object with simplexml I get only one 'that' and do not get its contents. When I use the script that creates the array, I get both that's, and all their parms as elements, but not the colors. I'm curious what else people are using. Jeff -- /I am a non sequitur.

I needed something similar for my module. First of all, I wanted it to be compatible with PHP4. This means I needed to use xml_parser functions. Second, I didn't want the user to have to install another module or library. I ended up using two functions (one is recursive): /** * Takes an XML string, and returns a multidimensional array. Each "dimension" * may be a text string, a key-value array of tag attributes, and/or another * multidimensional array containing child nodes. * * @param $string * String containing XML data to parse * @return * Multidimensional array with attributes, values, and children */function _discogs_xml_to_array(&$string) { $parser = xml_parser_create(); xml_parser_set_option($parser, XML_OPTION_CASE_FOLDING, 0); xml_parse_into_struct($parser, $string, $vals, $index); xml_parser_free($parser); $multi_array = array(); foreach ($vals as $val) { $tag = $val['tag']; if ($val['type'] == 'open') { if (isset($multi_array[$tag])) { if (isset($multi_array[$tag][0])) { $multi_array[$tag][]=array(); } else { $multi_array[$tag]=array($multi_array[$tag], array()); } $cv = &$multi_array[$tag][count($multi_array[$tag])-1]; } else { $cv = &$multi_array[$tag]; } if (isset($val['attributes'])) { foreach ($val['attributes'] as $k => $v) { $cv['_attributes'][$k] = $v; } } $cv['_nodes'] = array(); $cv['_nodes']['_recursion'] = &$multi_array; $multi_array = &$cv['_nodes']; } elseif ($val['type'] == 'complete') { if (isset($multi_array[$tag])) { if (isset($multi_array[$tag][0])) { $multi_array[$tag][] = array(); } else { $multi_array[$tag] = array($multi_array[$tag], array()); } $cv = &$multi_array[$tag][count($multi_array[$tag])-1]; } else { $cv = &$multi_array[$tag]; } if (isset($val['attributes'])) { foreach ($val['attributes'] as $k => $v) { $cv['_attributes'][$k] = $v; } } if (isset($val['value'])) { $cv['value'] = trim($val['value']); } } elseif ($val['type'] == 'close') { $multi_array = &$multi_array['_recursion']; } } // Clean up the recursion and merge attributes with child nodes $multi_array = _discogs_xml_clean($multi_array); return $multi_array;} /** * Helper function for _discogs_xml_to_array. * * Cleans up the array structure, by getting rid of the recursive data, and * merging the values, attributes and child nodes. * * @param array $old_array * Old array to clean up * @return array $new_array * Cleaned up array */function _discogs_xml_clean($old_array) { // Double check that it's an array, for recursion if (!is_array($old_array)) { return $old_array; } foreach ($old_array as $k => $v) { if ($k === '_recursion') { unset($old_array[$k]); } elseif (is_array($old_array[$k]['_nodes']) && is_array($old_array[$k]['_attributes'])) { $old_nodes = _discogs_xml_clean($old_array[$k]['_nodes']); $new_merged = array_merge($old_array[$k]['_attributes'], $old_nodes); $new_array[$k] = $new_merged; } elseif (isset($old_array[$k]['value']) && is_array($old_array[$k]['_attributes'])) { $value['value'] = trim($old_array[$k]['value']); $new_merged = array_merge($old_array[$k]['_attributes'], $value); $new_array[$k] = $new_merged; } elseif (is_array($old_array[$k]['_nodes'])) { $new_array[$k] = _discogs_xml_clean($old_array[$k]['_nodes']); } elseif (isset($old_array[$k]['_attributes'])) { $new_array[$k] = $old_array[$k]['_attributes']; } elseif (isset($old_array[$k]['value'])) { $new_array[$k] = $old_array[$k]['value']; } else { $old_nodes = _discogs_xml_clean($old_array[$k]); $new_array[$k] = $old_nodes; } } return $new_array;} So, if you passed your XML file to the first function, this would be the resulting multidimensional array: Array( [this] => Array ( [that] => Array ( [0] => Array ( [parm1] => a [parm2] => b [parm3] => c [value] => red ) [1] => Array ( [parm1] => e [parm2] => f [parm3] => d [value] => blue ) ) )) It's complicated, but it works. -Karl.

If you check out the project page at http://drupal.org/project/querypath you will see that it is licensed to be compatible with d.o.

After Drupal itself, and then Drush, Querypath is the next most useful tool in my arsenal. I couldn't imagine going back to SimpleXML. The code performs well, is well documented, and Matt Butcher, the maintainer, is very responsive on the mailing list and queues. Not only that, but he's a pretty all around great guy, going above and beyond to answer questions and ease adoption. So, in short, as one small part of this community, I would say, yes, add QP to your toolbox to easily solve these kinds of problems.

DevScore Module
by Fred Jones 24 Mar '11

24 Mar '11

Can I ask a question? This new module http://drupal.org/sandbox/robertcfi/1104066 says it's a sandbox, but it also says "This module is currently in production" in the text. My guess is that it will go nowhere (it is his first module also), but does anyone else think the criteria for scores are *ludicrous*? Since when is a site with more nodes and more modules and more users any "better" than a site with less? Should be obvious but a specialty site may be optimized and beautiful and in all ways built "perfectly" yet have a small user base and of course a small number of modules and nodes, yet far "better" than a big fat site slapped together with 1000 modules that serve only to SLOW it down. And also, since when does one have to know SEO to be a good developer?!?? Perhaps this is offtopic. Sorry. :( F PS: At least ranting made me feel better.

node_load using cck fields
by Lluís Forns 24 Mar '11

24 Mar '11

I want to load a node using cck fields instead of nid or core fields. Is there a "no-sql" way of doing this? I have read that maybe I could achieve it using views, but I think it would be an overkill. What I want to achieve is something like this: $inscripcio = node_load(array( 'type' => 'inscripcio', 'field_alumne' => $nid_alumne, 'field_convocatoria' => $nid_convocatoria, )); any hint? If I could get which tables use a cck type and how to join them, maybe I could code a "generic" way to do this, so if cck-type is changed, there is no problem. -- *Les normes hi són perquè hi pensis abans de saltar-te-les *La vida és com una taronja, què esperes a exprimir-la? *Si creus que l'educació és cara, prova la ignorància. *La vida és com una moneda, la pots gastar en el que vulguis però només una vegada. *Abans d'imprimir aquest missatge, pensa en el medi ambient.

Two tiered menus in D7 when the top level is user specific
by Rob Thorne 22 Mar '11

22 Mar '11

I'm looking into a two tiered menu in a D7 application where the second level of the menu is standard, but the top level is different for every user. To make this concrete, suppose the user is a teacher at a school where the teacher uses multiple rooms, and needs to order materials for each room separately. Each teacher has a separate list of rooms, but the the pages we track -- class lists, crafts inventory, furniture... are the same for each room. So for teacher A, we might have a set of menus like this: * Room 220 o Class List o Crafts Inventory o Furniture * Room 221 o Class List o Crafts Inventory o Furniture and so on. It's clear to me how to do a loader function and menu handler for a link like 'teacher/%teacher/room/%/class_list', but I don't see how to populate the level of the menus for '220' and '221' in the 3 position. In Drupal 5, I used to use the !$may_cache argument for these sorts of things. I'm not arguing that this was efficient, but it did work. What hooks would I need to use in addition to hook_menu to make this work in Drupal 7? Thanks, Rob Thorne Torenware Networks
