Powershell Regex to replace XML tag values -


i'm trying parse following xml file using powershell without loading xml document using [xml] since document contain errors.

<data>   <company>walter & cooper</company>   <contact_name>patrick o'brian</contact_name> </data>

to load document need fix errors replacing special characters follows 

& &amp; < &lt; ' &apos; etc..

i know find , replace characters in document

(get-content $filename) | foreach-object {   $_-replace '&', '&amp;' `     -replace "'", "&apos;" `     -replace '"', '&quot;'} | set-content $filename

but replace characters everywhere in file, i'm interest in checking characters inside xml tags <company> , replacing them xml safe entities resultant text valid document can load using [xml].

something should work each character need replace:

$_-replace '(?<=\w)(&)(?=.*<\/.*>)', '&amp' `   -replace '(?<=\w)(')(?=.*<\/.*>)', '&apos;' `   -replace '(?<=\w)(")(?=.*<\/.*>)', '&quot;' `   -replace '(?<=\w)(>)(?=.*<\/.*>)', '&gt;' `   -replace '(?<=\w)(\*)(?=.*<\/.*>)', '&lowast;' } | set-content $filename

which positive look-behind non-word character, capturing group followed positive look-ahead.

i've tried various ways coerce xterm (versions 285 , 292) copy selection clipboard clipboard whenever press ctrl-shift-c. promising way far has been, in ~/.xresources, put this: xterm*vt100.translations: #override \ ctrl shift <keypress> c: copy-selection(clipboard) \n\ ctrl shift <keypress> v: insert-selection(clipboard) ctrl-shift-v works perfectly, copying has nuance... if restart xterm, highlighting text puts things in primary clipboard; expected, proper, default behavior. if hit ctrl-shift-c, copies current selection clipboard clipboard. the bug, however, if highlight text after first time pressed ctrl-shift-c, you'll see highlighting copies both primary and clipboard. cannot figure out how stop xterm updating clipboard upon selection... , doesn't make sense me in first place. i said, @ specific point in time, copy selection clipboard... yet starts updating automatically upon selection after doing once... anyone have workaround...
