Regular Expressions - match content in XML page

Question

I am new to regular expressions and need to write one that will pull certain data out of an XML page. For instance,

<name>Number of test runs</name>
<value>2</value>

The only number I need to pull is the 2. I want it to look at the XML tag Name so I don't pull from any other numbers on the page. Below is what I have but I am matching all the content instead of just the 2. Any help would be appreciative.

Current Regular Expression:

/<name>Number of Failed BGPs</name>\n<value>(.+?)/

Answer 1

You said the problem is that it's matching all the content, not just the value (2). But you do need to match all the content to ensure it's the correct <name> tag.

The distinction you want is the matched group, designated by parens.

/<name>Number of Failed BGPs<\/name>\n<value>(.+?)<\/value>/

You want to get the first matched group, which should be just the value itself. Notice I also added the </value> tag to the regex. If you don't, your lazy quantifier would pick up only the first digit.
