escaping

I'm trying this $Global:commandBlock={ Start-Transcript -path $projectFolder\gruntLog.txt; grunt $argList; Stop-Transcript } $cmdProc=start-process powershell -ArgumentList ('-command `$Global:commandBlock') -WorkingDirectory $fwd -PassThru -NoNewWindow:$NoNewWindow And keep getting $commandBlock : The term '$Global:commandBlock' is not recognized as the name of a cmdlet, function, script file, or operable program. My guess was it has to do with scope. But making variable global didn't help. Adding -args $commandBlock like that: -ArgumentList ('-command `$Global:commandBlock -args "

I load xml file into DOM model and analyze it. The code for that is: public class MyTest { public static void main(String[] args) { Document doc = XMLUtils.fileToDom("MyTest.xml");//Loads xml data to DOM Element rootElement = doc.getDocumentElement(); NodeList nodes = rootElement.getChildNodes(); Node child1 = nodes.item(1); Node child2 = nodes.item(3); String str1 = child1.getTextContent(); String str2 = child2.getTextContent(); if(str1 != null){ System.out.println(str1.equals(str2)); } System.out.println(); System.out.println(str1); System.out.println(str2); } } MyTest.xml <tests> <test name

After attempting to answer the question to this post Another SO post I noted that this Function('return "\\101\\40\\171\\145\\154\\154\\157\\167\\40\\142\\165\\164\\164\\157\\156\\56"')() or Function('return "\101\40\171\145\154\154\157\167\40\142\165\164\164\157\156\56"')() both return the same string - "A yellow button." In regards to the question I linked to above, the JS code snippet is run in a tag. I have also noted in the past that when working on some JSON strings, that the '\' was needed over '\' When is it necessary? Why is it necessary? If it is not necessary, then why is it done?
