xml - How do I XPath to attribute whose namespace is different to its ancestor's -


i'm trying query codebase attribute on line 11 of xml file.

<?xml version="1.0" encoding="utf-8"?> <asmv1:assembly xsi:schemalocation="urn:schemas-microsoft-com:asm.v1 assembly.adaptive.xsd" manifestversion="1.0" xmlns:asmv1="urn:schemas-microsoft-com:asm.v1" xmlns="urn:schemas-microsoft-com:asm.v2" xmlns:asmv2="urn:schemas-microsoft-com:asm.v2" xmlns:xrml="urn:mpeg:mpeg21:2003:01-rel-r-ns" xmlns:xsi="http://www.w3.org/2001/xmlschema-instance" xmlns:asmv3="urn:schemas-microsoft-com:asm.v3" xmlns:dsig="http://www.w3.org/2000/09/xmldsig#" xmlns:co.v1="urn:schemas-microsoft-com:clickonce.v1" xmlns:co.v2="urn:schemas-microsoft-com:clickonce.v2">     <assemblyidentity name="vcilapp.application" version="0.0.0.0" publickeytoken="0000000000000000" language="neutral" processorarchitecture="msil" xmlns="urn:schemas-microsoft-com:asm.v1" />     <description asmv2:publisher="vcil" asmv2:product="vcilapp" xmlns="urn:schemas-microsoft-com:asm.v1" />     <deployment install="true" minimumrequiredversion="0.0.0.0" co.v1:createdesktopshortcut="true">         <subscription>             <update>                 <beforeapplicationstartup />             </update>         </subscription>         <deploymentprovider codebase="file://vandc/vcfileshare/vc apps/dialler/vcilapp.application" />     </deployment>     <compatibleframeworks xmlns="urn:schemas-microsoft-com:clickonce.v2">         <framework targetversion="4.5" profile="full" supportedruntime="4.0.30319" />     </compatibleframeworks>     <dependency>         <dependentassembly dependencytype="install" codebase="application files\vcilapp_3_0_9_2705\vcilapp.exe.manifest" size="26738">             <assemblyidentity name="vcilapp.exe" version="0.0.0.0" publickeytoken="0000000000000000" language="neutral" processorarchitecture="msil" type="win32" />             <hash>                 <dsig:transforms>                     <dsig:transform algorithm="urn:schemas-microsoft-com:hashtransforms.identity" />                 </dsig:transforms>                 <dsig:digestmethod algorithm="http://www.w3.org/2000/09/xmldsig#sha256" />                 <dsig:digestvalue>7ikkd3ls5fcflulntbyd54jzwk/4l5dnnz4rgbzelb8=</dsig:digestvalue>             </hash>         </dependentassembly>     </dependency> </asmv1:assembly>

it need along lines of /assembly/deployment/deploymentprovider/@codebase namespace prefixes need accounted for. deployment element possibly causing problem it's not in asmv1 namespace ancestors.

can provide xpath codebase attribute?

you didn't give details of in context use xpath expression, generally:

  1. map asmv1 urn:schemas-microsoft-com:asm.v1
  2. map asmv2 urn:schemas-microsoft-com:asm.v2

then expression want: 

/asmv1:assembly/asmv2:deployment/asmv2:deploymentprovider/@codebase

linux - xterm copying to CLIPBOARD using copy-selection causes automatic updating of CLIPBOARD upon mouse selection -

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...

c++ - qgraphicsview horizontal scrolling always has a vertical delta -

Image
i've subclassed qgraphicsview custom canvas used in cad application. i've reimplemented qgraphicsview::wheelevent check keyboard modifiers control key and, if control key pressed, zoom. i'm trying implement horizontal scroll when user holds shift , uses wheel. the problem i'm having horizontal scrolling always scrolls 0.279. not huge problem, hugely annoying , points else being wrong. so, here questions: is right way implement horizontal scrolling? if not, is? how eliminate delta of 0.279? thanks in advance. code , sample output below void myview::zoom(int delta) { double factor = pow(1.2, delta/abs(delta)); this->scale(factor, factor); } void myview::scrollhorizontal(int level) { qpointf center = maptoscene(viewport()->rect().center()); qdebug() << "center: " << center.x() << ", " << center.y(); centeron(qpointf(center.x() - level, center.y())); } void myview::wheelevent(qwheeleve...
