[PHP] xpath question

2008-02-19 Thread RJO 
Hey guys,

I have a form accepting a KML file from users and from there I want to
draw polylines based on a KML file's
PlacemarkerLineStringcoordinates element.


The problem I am having is that sometimes the KML file can have a
documentfolder or folderdocument or none of the above, or any
number of random scenarios in the KML file making it hard to parse.


To deal with this randomness I'm using an xpath and I think I have it
right but it just wont work... the code:
$result = $xml-xpath('Placemark/LineString/coordinates');


An the particular XML file I am trying to pull from looks like:
?xml version=1.0 encoding=UTF-8?
kml xmlns=http://earth.google.com/kml/2.1;
Document
namecoehilltotweed.kml/name

Any ideas why this won't work?

It's the namespace. I'm not positive (I can't test on this computer)
but try this:

$result = $xml-xpath(*[local-name()='Placemark' and
namespace-uri()='http://earth.google.com/kml/2.1']/*[local-name()='LineString'
and 
namespace-uri()='http://earth.google.com/kml/2.1']/*[local-name()='coordinates'
and namespace-uri()='http://earth.google.com/kml/2.1']);

That may be a little off, but that's the idea, anyway.

If you're just trying to get the coordinates, you can use:

$result = $xml-xpath('//coordinates');

I have a feeling you'll want to do more parsing than that, thought.

In the case of your example, I believe it should be the following:

$result = $xml-xpath('Folder/Placemark/LineString/coordinates'); _or_

$result = $xml-xpath('Document/Folder/Placemark/LineString/coordinates'); 

I can never remember. One of those 2 will work.

[PHP] XPath question

2007-02-05 Thread Eli 

Hi,

ns:root i=0
tag
ns:node i=1/
/tag
ns:anothernode i=2
ns:notme i=3
ns:meneither i=4/
/ns:notme
anothertag/
/ns:anothernode
/ns:root

I need to retrieve a list of all the INNER ns:* nodes (not the root 
i=0 node), that do not have an ancestor of any ns:* node but the root 
ns:root i=0 node.

In other words: get all ns:* nodes with i in {1,2}.

-thanks!

[PHP] xpath question

2006-06-29 Thread bruce 
hi...

in getting information on xpath/xml.. i thought i'd ask these lists as
well...

i'm trying to find out if there's a tool that i could use to load an HTML
web page into, that would allow me to point to a given item/element within
the Tree/DOM structure and allow me to see what the Xpath statement would be
to generate that given itm/element of the Tree...

i've seen a few tools but none that have exactly what i'm looking for...

has anyone knowledge of any kind of tool/plugin like this? i'd also like to
hear your comments pro/con of the tool if you've actually used it!!

thanks

-bruce
