<ns1:Abstract xml:lang="en-US">Uses mean and standard deviation for each environmental variable separately to calculate bioclimatic envelopes. Level of fitness between the environmental values on a point and the respective envelopes classifies points as Suitable, Marginal, or Unsuitable for presence.
Implements the Bioclimatic Envelope Algorithm. For each given environmental variable the algorithm finds the mean and standard deviation (assuming normal distribution) associated to the occurrence points. Each variable has its own envelope represented by the interval [m - c*s, m + c*s], where 'm' is the mean; 'c' is the cutoff input parameter; and 's' is the standard deviation. Besides the envelope, each environmental variable has additional upper and lower limits taken from the maximum and minimum values related to the set of occurrence points.
In this model, any point can be classified as:
Suitable: if all associated environmental values fall within the calculated envelopes;
Marginal: if one or more associated environmental value falls outside the calculated envelope, but still within the upper and lower limits.
Unsuitable: if one or more associated enviromental value falls outside the upper and lower limits.
Bioclim's categorical output is mapped to probabilities of 1.0, 0.5 and 0.0 respectively.</ns1:Abstract>

J'utilise jQuery. J'ai converti le xml en dom et maintenant je dois l'interroger pour extraire l'enfant du nœud Status.
$.ajax({
type: 'GET',
url: "php/proxy.php?proxy_url=" + obj.requests[i].output,
contentType: "text/xml",
dataType: "text/xml",
async:false,
success: function(xml){
var $dom = $.xmlDOM(xml, function(error){
alert('A parse error occurred! ' + error);
});
//extract data
}});
Merci beaucoup.
C'est complètement inutile. Utilisez "xml" comme "dataType" et vous obtenez un document XML. –
Je suis d'accord, utile de savoir à propos de xml2json, mais trop pour cette tâche. – artlung
