xml xmlns namespace and xsi_type extractions from xml using bash

Greetings.
I need to know how to pull the values from XML header information:
<?xml version="1.0" encoding="UTF-8"?><?xml-stylesheet href="http://www.accessdata.fda.gov/spl/stylesheet/spl.xsl" type="text/xsl"?>
<document xmlns="urn:hl7-org:v3" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="urn:hl7-org:v3 http://www.accessdata.fda.gov/spl/schema/spl.xsd">

Open in new window


In addition, in several areas I have tags with xsi_type: attributes in it.  They do not show up in XPATH locations.  (ie. <tag xsi_type="CE" ... />

I am obligated to pull the xmlns, xmlns:xsi, xsi:schemaLocation and the specific tag (assuming I know the xpath to the tag) into a bash variable to do something with it.  Is this possible?

Thanks.

I need all of them.
I need to put them into a variable in BASH so I can put it somewhere.

Thanks.

xsi:type (it should be colon and not underscore) should show up in the XPath (given the right expression).  Are you sure it does not?

For parsing XML, you really want a true parser of some sort.  Since you reference XPath, I'm assuming you have access to one.  Otherwise, I would write a small script in Perl (or your language of choice) to extract the pieces you need.

That said, you can extract XML using regexes but it's tricky.
