We are running a PowerShell command and in that PowerShell command we are calling the XML file and trying to install veeam software. I am getting an error like
hexadecimal value 0x00, is an invalid character. Line 2, position 1.
Could someone please kindly help me to fix this issue? We have no idea about that.
I have attached the XML file below.
<event id="113" title="Unexpected error occurred."> <description><![CDATA['.', hexadecimal value 0x00, is an invalid character. Line 2, position 1.]]></description> </event>

Your posted XML does not have the posted error — it is well-formed — but here are some general reasons and remedies for an XML illegal character error:
The "XML" file has an illegal character:
See XML Recommendation for the allowed characters in XML :
[2] Char ::= #x9 | #xA | #xD | [#x20-#xD7FF] | [#xE000-#xFFFD] | [#x10000-#x10FFFF]
Examine the file in a dedicated XML editor or a hex editor such as ImHex or an XML or hex mode of a general purpose editor.
Remove the illegal character.
Fix the upstream source that produced the bad XML if possible.
The intended XML file is not making its way to the XML application:
application/xml.)Your declared encoding does not match the reality of your file's bytes. (Although this usually would result in different sorts of errors or output.)
