Reading in text file

[Sebastian2011]

I have a text file that contains something like this:

<setting name="ip_address" serializeAs="String">
                <value>239.0.0.1</value>

I want to be able to search through the text file and based upon finding <setting name="ip_address" serializeAs="String">, I'd like to get the 239.0.0.1

New to Labview.  So I'm not sure how to do it.  Currently using LabView 2012.  Thanks.

That looks a lot like XML.  You might want to look at the few XML examples in the LabVIEW Example Finder (do a search for XML in the Example Finder).

It is xml, but it doesn't have the xml extention.  From what I've seen, the .xml is required.  I'm currently using read from text file, but can't figure out how to do the search.

Generally, your txt file will be read in as a spreadsheet string or as an array of strings.

You can use Match Pattern to look for <setting name="ip_address" serializeAs="String">\r<value>

Three outputs will contain the text leading up to the search string, the search string, and the rest (the rest will contain the ip_address followed by the rest of the text file),

Use Match Pattern again looking for </value> that comes after the ip_address.  The first output will contain the ip_address.

Thansks for the help.  When I enter <setting name="port" serializeAs="String"> it finds the string, but when I enter <setting name="port" serializeAs="String">\r<value> it does not find it.

Copy/paste that section of text from the file into a string constant.  (I may have missed some tab characters or was incorrect in how I added the return character).

Cool, it works. 

     <setting name="port" serializeAs="String">
                <value>5678</value>

How can I strip off the trailing </value>

[pjr1121]

Use the same vi with </value> as the search string.  The port will be the string returned before the search results (top output)
