Bug description: Will not parse tags with certain chars
Description:
------------
Note: SimpleXML has issues parsing tags with ":" in it.
GML tags for example are formatted like:
<gml:name>Foo</gml:name>.
In the SimpleXML Documentation, it states to put tags between {} that
could contain chars. that could break the parser, like "-" for example.
In our example below:
$xml->firstLayer->secondLayer->{'gml:name'}
will not be parsed by SimpleXML, but SimpleXML will NOT throw an error or
lead you to believe that it has NOT parsed it.
I was parsing output from hostip.info which uses XML as an output with
GML.
Here is an example of the XML I was working with when I cam a
Reproduce code:
---------------
---
>From manual page: book.simplexml
---
$ipAddr = "209.240.56.78";
$data = file_get_contents("http://api.hostip.info/?ip=".$ipAddr);
$xml = @simplexml_load_string(str_replace(":", "_", $data));
//SimpleXML has issues parsing the ":", replacing it with underscore to
make this work.
$city = $xml->gml_featureMember->Hostip->gml_name;
$country = $xml->gml_featureMember->Hostip->countryName;
$country_abbrev = $xml->gml_featureMember->Hostip->countryAbbrev;
$lat_long =
$xml->gml_featureMember->Hostip->ipLocation->gml_PointProperty->gml_Point->gml_coordinates;
echo $city
Expected result:
----------------
This is what XML looks like coming from the site:
<HostipLookupResultSet version="1.0.0" xmlns="http://www.hostip.info/api";
xmlns:gml="http://www.opengis.net/gml";
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";
xsi:schemaLocation="http://www.hostip.info/api/hostip-1.0.0.xsd";>
<gml:description>This is the Hostip Lookup Service</gml:description>
<gml:name>hostip</gml:name>
<gml:boundedBy>
<gml:Null>inapplicable</gml:Null>
</gml:boundedBy>
<gml:featureMember>
<Hostip>
<gml:name>(Unknown City?)</gml:name>
<countryName>(Unknown Country?)</countryName>
<countryAbbrev>XX</countryAbbrev>
<!-- Co-ordinates are unavailable -->
</Hostip>
</gml:featureMember>
</HostipLookupResultSet>
Based on my echo of $city, I would expect to see:
Providence RI
Actual result:
--------------
Blank - nothing.
SimpleXML will not throw an error if it runs into an issue parsing
anything with a ":" in the tag.
