editing an attribute of an XML file

[dandan86]

hey guys,
so, here is the issue: I got this XML with a very long attribute in it (the attribute is more than a few lines long, it represents a part of an html document using escape tags) - now, I need to edit specific parts of that attribute - my problem is: say i have the attribute node - how can i change/erase specific parts of the attributes, like, how can tell the parser to go "until you reach some certain word".
to illustrate: say it's something like that:
<element att="&lg;b&gd;some text bla bla&lg;/b&gt;"
that's how the attribute looks like, it basically represents:
<b>some text bla bla</b>
so, how can i reach, say, the start of the sentence ("some text bla bla") and change it to another sentence

thanks in advance

Hey,
I am just using editplus - i am rather a beginner.
I can download other tools if that's the way to do it.

thanks.
