c# - Linq to xml query not returning any values -


i'm pulling xml list of sharepoint site collection users , trying query innerxml. innerxml looks this:

<users xmlns="http://schemas.microsoft.com/sharepoint/soap/directory/">  <user id="91" name="jane smith" loginname="domain1\jsmith" /> <user id="814" name="brad jones" loginname="domain1\bjones" /> <user id="1252" name="charles johnson" loginname="domain2\cjohnson" /> </users>

query not returning (el null), though there user id 814.

xmlnode siteusers = tempug.getusercollectionfromsite(); xelement root = xelement.parse(siteusers.innerxml);     ienumerable<xelement> siteuserselement =         el in root.elements("user")         (string)el.attribute("id") == "814"         select el; foreach (xelement el in siteuserselement) console.writeline("el: " + el);

root contains innerxml text, don't think problem has sharepoint.

you're not specifying namespace in elements call. fortunately easy in linq xml:

xnamespace ns = "http://schemas.microsoft.com/sharepoint/soap/directory/"; ... el in root.elements(ns + "user");

if know id attribute integer, i'd make clear, , avoid using query expression when doesn't you:

// todo: find nicer way of doing this; shouldn't need parse again xelement root = xelement.parse(siteusers.innerxml); var siteuserelements = root.elements(ns + "user")                            .where(el => (int) el.attribute("id") == 814);  foreach (xelement el in siteuserelements) {     console.writeline("el: " + el); }

php - Calling a template part from a post -

i include iframe within post in wordpress. located inside content of post, meaning cannot in post template file, otherwise either before or after. i'd add facebook plugin within posts: <div id="socialwrap"><div class="fb-like" data-href="http://onlinearizonahomes.info" data-send="true" data-width="450" data-show-faces="true" data-font="arial"></div></div> i thinking of calling template part within post <?php get_template_part( 'social' ); ?> cannot use php within post without plugin (i'd avoid using plugin this). an alternative using javascript create html in post, seems unnecessary use of javascript. what best way add html within wordpress post? you can use shortcode. add functions.php function cudjex_fbshare( $atts, $content = null ) { global $post; $link = get_permalink($post->id); return '<div id="socialwrap...
