使用Java删除数字xml标签

Question

I have the following xml:

<?xml version=\"1.0\"?>
<1>
<TITLE>A Sample Article</TITLE>
<SECT>The First Major Section      <PARA>This section will introduce a subsection.</PARA>
    <2>
    <SECT>The Subsection Heading         <PARA>This is the text of the subsection.         </PARA>      
    </SECT>
</SECT>
</ARTICLE>

I want to remove the numeric tags "<1>" and "<2>" using Java.

Parsers won't work as its an invalid xml. I need another solution such as a regular expression or any other idea.

Answer 1

You can just use the replaceAll method.

String str = "YOUR XML HERE";
str = str.replaceAll("<[12]>", "");

Or as Boheamian pointed in his comment you can use the \\d shortcut for digits:

str = str.replaceAll("<\\d>", "");

Btw, if you have more than <1> and <2> , like <n> being n whatever number, then you could use:

str = str.replaceAll("<\\d+>", "");
