xpath - msxml selectnodes: namespace in text node -

-

i have following xml file:

<root xmlns="http://someurl/element" xmlns:text="http://someurl/text">    <elements>      <element>        <id>text:some_id</id>        <!-- other elements -->      </element>      <element>        <!-- other elements -->        <reference>           <link ref="text:some_id" />        </refernce>      </element>    </elements> </root>

i want select child elements of elment node have element id=text:some_id reference node. want in c++ using selectnodes method of ixmldomnode object msxml parser.

in following exmaple have refence node selected in pchild , selectionnamespaces propetey set xmlns:n="http://someurl/element":

msxml2::ixmldomnodeptr pselectednodes =     pchild->selectnodes("../../n:element[n:id=n:link/@ref]/n:*"); __assert(pselectednodes->length > 0)

this not working. doing wrong?

the n:link/@ref part of xpath query evaluated in context of element conditional criteria applied; in case ../../n:element.
can’t reference overall context within conditional section; in other words, context node different inside , outside of [square brackets].

i’m afraid have extract pchild->selectsinglenode("n:link/@ref")->text separately, , 'manually' insert xpath query.

how set z-index drawing object when using drawingcontext.drawxxx() methods? the object drawn last have higher z index. can't change index of drawn objects. way draw in order. if using wpf (as placed tag), can use, example, canvas control. create shapes need like polyline obj = new polyline(); //... // ... set properties of obj and add them canvas uielementcollection: yourcanvasname.children.add(obj); //or yourcanvasname.children.insert(i, obj); first items of collection have higher z index. advantages in way: no need redraw on window changes, can anytime move objects , change order.

razor - Is this a bug in WebMatrix PageData? -

i think may have found bug in webmatrix's pagedata, not sure. concerns how pass data partial page calling page. in webmatrix documentation (tutorials, e.g. " 3 - creating consistent look ", , example code), pagedata recommended mechanism pass data between pages (e.g. content page layout page, or partial page). however have found not work other way, pass data partial page calling page. modifying or adding entries in pagedata in partial page, not seem calling page. cutting right down simplest possible example, in test page may have this: @{ pagedata["test"] = "initial entry"; } <p>before calling partial page, test value @pagedata["test"]</p> @renderpage("_testpartial.cshtml") <p>after returning calling page, test value @pagedata["test"]</p> and in _testpartial.cshtml page might have this: @{ pagedata["test"] = "modified entry"; } <p>in partial page...

android - layout with fragment and framelayout replaced by another fragment and framelayout -

edit: so after comments below, revisted , realized hanging me up. imagine client list , client details activity started : public class clientsmainactivity extends fragmentactivity { @override public void oncreate(bundle savedinstancestate) { super.oncreate(savedinstancestate); //studiotabopenhelper db; setcontentview(r.layout.main_client_activity); } } so works great, starts main_client_activity (defined in layout below, , call activity when button on main screen clicked): intent intent = new intent(getactivity(), clientsmainactivity.class); startactivity(intent); easy issue is, clientsmainactivity not call oncreateview or anything, sets layout layout defines fragment, , listfragment. fine cause not trying pass clientsmainactivity , if have hypothetical activity like: sessionmainsactivity called when click on session edit of client, not calling sessionsmainactivity same way (starts activity sets alayout), want layout set defines...
