Hi All,

Greetings.

Today new issue and solution.

Background

  • I am executing few PowerShell CMDLET in my PowerShell 7 app.
  • I required a string variable storing my bit long string.
  • As I am assigning my string variable I am getting an error

Error : No characters are allowed after a here-string header but before the end of the line

PowerShell command line interface displaying a parser error related to a malformed HTML doctype declaration.

Solution

  • I did research and understand the concept of here-string.
  • We have detailed article on here-string – PowerShell Learning: Here-String (@” “@)
  • Then I realized text in here-string always start with new line.
  • I have started the text on the same line.
  • It should be like that

PS C:\> $test = @"
>> {
>> <!doctype html><html xmlns="http://www.w3.org/1999/xhtml" xmlns:v="urn:schemas-microsoft-com:vml" xmlns:o="urn:schemas-microsoft-com:office:office"></html>
>> }
>> "@
PS C:\>
