我必须提取标签的内容,这就是我所拥有的:
<?xml version="1.0" encoding="utf-8"?>
<string xmlns="http://tempuri.org/">iVBORw0KGgoAAAANSUhEUgAAAU0AAAD6CAYAAAAlSBW9AAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAP+lSURBVHhehP1lnB3H1a4P75Ely8zMzOyYHcccjsNOHNtx7IDtJCbJgtEwM4tG0kgzghnRaEgMI2aWLNlisMVMlgxa73Wv2tvJ85xz ...
</string>
这就是我想要的:
iVBORw0KGgoAAAANSUhEUgAAAU0AAAD6CAYAAAAlSBW9AAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAP+lSURBVHhehP1lnB3H1a4P75Ely8zMzOyYHcccjsNOHNtx7IDtJCbJgtEwM4tG0kgzghnRaEgMI2aWLNlisMVMlgxa73Wv2tvJ85xz ...
我试过这个正则表达式:
iframeContents.match(/<string[^>]*>(.*?)<\/string>/i);
但是我一直得到字符串标签而不再是xml:
<string xmlns="http://tempuri.org/">iVBORw0KGgoAAAANSUhEUgAAAU0AAAD6CAYAAAAlSBW9AAAAAXNSR0IArs4c6QAAAARnQU1BAACxjwv8YQUAAAAJcEhZcwAADsMAAA7DAcdvqGQAAP+lSURBVHhehP1lnB...
答案 0 :(得分:0)
尝试
iframeContents.match( /<string[^>]*>([\s\S]*?)<\/string>/i )[1]
匹配返回一个数组,如果没有匹配则返回null
数组的第一个元素是整个匹配,第二个元素是第一个捕获组()
匹配的文本。
.
与换行符不匹配,但[\s\S]
会换行。

使用here
中的解析xml方法var parseXml;
if (typeof window.DOMParser != "undefined") {
parseXml = function(xmlStr) {
return ( new window.DOMParser() ).parseFromString(xmlStr, "text/xml");
};
} else if (typeof window.ActiveXObject != "undefined" &&
new window.ActiveXObject("Microsoft.XMLDOM")) {
parseXml = function(xmlStr) {
var xmlDoc = new window.ActiveXObject("Microsoft.XMLDOM");
xmlDoc.async = "false";
xmlDoc.loadXML(xmlStr);
return xmlDoc;
};
} else {
throw new Error("No XML parser found");
})
var xml = parseXml("...");
var text = xml.documentElement.firstChild.nodeValue;
