javascript - Loop Through XML Parse Function and Display in HTML -

-

I have a function that currently displays hard-coded XML data in an iPhone app; 

  Function View XMLFiles () {xmlhttp = new XMLHttpRequest (); Xmlhttp.open ("GET", "TestInfo.xml", incorrect); Xmlhttp.send (); XmlDoc = xmlhttp.responseXML; Document.getElementById ("docname"). InnerHTML = xmlDoc.getElementsByTagName ("document_name") [0]. ChildNode [0] .nodeValue; Document.getElementById ("Filetype"). InnerHTML = xmlDoc.getElementsByTagName ("file_type") [0]. ChildNode [0] .nodeValue; Document.getElementById ("fileloc"). InnerHTML = pathToRoot + "/" + document.getElementById ("docname"). InnerHTML; Document.getElementById ("docname1"). InnerHTML = xmlDoc.getElementsByTagName ("document_name") [1]. ChildNode [0] .nodeValue; Document.getElementById ("filetype1"). InnerHTML = xmlDoc.getElementsByTagName ("file_type") [1] .childNodes [0] .nodeValue; Document.getElementById ("fileloc1"). InnerHTML = pathToRoot + "/" + document.getElementById ("docname1"). InnerHTML; }   
 And I want to put it in a loop so that when I add the option of uploading the file the file will be automatically loop and click on a button while displaying the data. Instead of code it will be clicked on. Button is coded;  
  & lt; Button onclick = "viewXMLFiles (); document.getElementById ('showDocumentLink'). Style.display = 'block';" & Gt; View Document Information & lt; / Button & gt; & Lt; Br>   
 And the page is set to load XML in this form;  
  & lt; Div id = "doclist" & gt; & Lt; H2 & gt; Document 1; & Lt; / H2 & gt; & Lt; Label & gt; Document name; & Lt; / Labels & gt; & Lt; Br> & Lt; Span id = "docname" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; Label & gt; File type & lt; / Labels & gt; & Lt; Br> & Lt; Span id = "filetype" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; Label & gt; File Location & lt; / Label & gt; & Lt; Br> & Lt; Span id = "fileloc" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; / Div & gt; & Lt; Div id = "doclist" & gt; & Lt; H2 & gt; Document 2; & Lt; / H2 & gt; & Lt; Label & gt; Document name; & Lt; / Labels & gt; & Lt; Br> & Lt; Span id = "docname1" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; Label & gt; File type & lt; / Labels & gt; & Lt; Br> & Lt; Span id = "filetype1" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; Label & gt; File Location & lt; / Label & gt; & Lt; Br> & Lt; Span id = "fileloc1" & gt; & Lt; / Span & gt; & Lt; Br> & Lt; / Div & gt;   
 I'm really new to XML files and how to parse them for using Javascript, so there is some help in showing me that they  for  The loop is great. I do not really know how to do it, so any help would be greatly appreciated. Thanks in advance :)   
 
 
 Try it ....  
  XmlDoc = $ .parseXML (xml), $ xml = $ (xmlDoc), $ title = $ xml.find ("document_name"); . $ ("# DOCNAME") enclosed ($ title.text ());

I do not think this is a relativant code. Can anyone tell me what should I do? I have already installed something to remove the password but Solver is still asking for password and I can not get rid of it! itemprop = "text"> Solver Excel is add-in If you want to delete it, then Excel Application & gt; Options & gt; Add-ins & gt; Search for 'Go to' button and gt; Uncheck the solver on the list like press something (I can not give you the exact path because I have the Polish version of Excel). Trying to open Solver's VBA code is not good because it There is allegedly copyright. Besides, I do not think Solver creates any disadvantages while working with Excel or VBA.

github - Teamcity & Git - PR merge builds - anyway to get HEAD commit hash? -

-
I have a team city build project with Gitbab VCS route, I have been triggered for both / head on PR and / Merge the referee. The annoying thing is that you can not do anything useful with the merged hash - it is not present in Gitobb. I want to exclude newsgate packages with head in gutub comet situations in the version number along with Hewash (Newsaging 7) for the music build, but against head hash. However, I can not see a way to get the head hashes while constructing that merge. I just want to head because it's useless - we only care about merge. (PR - Pull Request) This command works reliably while running One on / merge is git log --no-merge -1 ---- = '% h'
