使用jsoup设置元标记的内容值

Question

I have an HTML document with a number of meta tags

<meta name="donald" content="duck" />
<meta name="micky" content="mouse" />
<meta name="daisy" content="duckling" />
<meta name="scrooge" content="macduck" />

I am able to get the content values ok but wish to change "mouse" to "horse" say.

Answer 1

Example:

final String html = "<meta name=\"donald\" content=\"duck\" />\n"
        + "<meta name=\"micky\" content=\"mouse\" />\n"
        + "<meta name=\"daisy\" content=\"duckling\" />\n"
        + "<meta name=\"scrooge\" content=\"macduck\" />";

Document doc = Jsoup.parse(html, "");

Element mouse = doc.select("meta[content=mouse]").first();
mouse.attr("content", "horse");

You just have to select the proper tag and change the attributes value.

Explanation:

Element mouse = doc.select("meta[content=mouse]").first();

Select all meta -tags, with attribute content with value mouse ; since select() returns a list of tags, first() is used to get the first one.

mouse.attr("content", "horse");

Change value of attribute content .
