Hi Josh, It's ok to use item(0) with the xpath approach. I was discouraging the way you were finding the <Text> nodes with getElementsByTagName(), since that would return all <Text> nodes in the CCR's section.
With xpath, you can be more procise. I've posted a sample here: http://code.google.com/apis/health/docs/1.0/developers_guide_php.html#ExtractCCRElements Eric On Jan 9, 8:10 am, Josh <[email protected]> wrote: > Thanks for the input, I appreciate the help.
