正则表达式查找和替换固定标签内的逗号并使用记事本++更改数字

Question

there is a XML-File with a comma instead of a point inside a specific tag.

So for example this Tag: <UPAvg>126,502</UPAvg> should be <UPAvg>126.502</UPAvg>

or <UPAvg>90,31</UPAvg> should be <UPAvg>90.31</UPAvg>

so only the comma in this specific tag should be turned into a point. The numbers are changing, so I tried to only search for the comma and replace it with the point inside this tag. But I can't get it. Can anybody help me?

Answer 1

Find this: ,(?=\d*</UPAvg)
Repleace with this .

• , Find ,
• ?= lookahead, when, is found the regex engine should check to see what is after (ahead).
• \d zero or more digits
• </UPAvg match </UPAvg literally

In plain english. When comma is found, check characters after and if there is digits after and the end tag </UPAvg . There is a match, replace with.
