Powershell TrimEnd trims trailing e's

I've been tasked with converting XML files exported from PDFs into XML files usable by another program. I'm using Powershell for this. I have noticed that when I trim the end of lines, if there is a trailing e, the e is also removed. And it's not just one e. If there are multiple e's, they are all trimmed. For example:

$lines[i].TrimStart(">").TrimEnd("</field")

If the line given is:

>123 Sycamore</field

The result is:

123 Sycamor

If the line given is:

>Agee</field

The result is:

Ag

Interestingly, this only happens to lowercase e's. So, if the line is:

>LANE</field

The result is:

LANE

I wasn't able to locate anything on technet or in the documentation. (Maybe I'm searching for the wrong thing.)

Anyone have any ideas on this? Am I implementing the function incorrectly?

TrimEnd takes a char[] as parameter, not a string. PowerShell will implicitly convert the string to its underlying characters array, which will then mean: Remove the following characters from the end of the string: <, /, f, i, e, l, d. The documentation also points this out quite clearly, so if you didn't arrive at this page, then yes, I guess you were searching for the wrong thing :-)

If you meant to remove the string </field> from the end of another string, you can use a regular expression:

$s -replace '</field>$'

You can even combine that with your TrimStart in this case:

$lines[$i] -replace '^>|</field>$'
