The XML code block contains HTML code instead of the expected XML tags.
Converting these to proper XML format should at least make it readable.
Also replaced "ps" with "xml" as the correct code block syntax name.
Ref. #3819 ([LOC]"<"needs to be replaced with"<", ">"needs to be
replaced with">")
(Should close issue ticket #3819 after migration to
docs.microsoft.com/en-us/ and later updated to the Japanese page.)
