如何使用java修剪xml标记和值之间的空格

I have an xml file like this

我有一个像这样的xml文件

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

This is the actual XML file. In our application, we receive this xml as a String.

这是实际的XML文件。在我们的应用程序中,我们将此xml作为String接收。

But somehow, due to hardware problems, the application is receiving the xml like the following.

但不知何故,由于硬件问题,应用程序正在接收xml,如下所示。

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove+++</to>
<from>Jani+</from>
<heading>Reminder++++</heading>
<body>Don't forget me this weekend!</body>
</note>

In my java method I wrote code like this,

在我的java方法中,我编写了这样的代码,

//It will trim all the + in the xml.
if(xml.indexOf("[+]")!=-1)){
xml = xml.replaceAll("[+]","").trim();
}

This gave a result like the following.

这给出了如下结果。

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove  </to>
<from>Jani </from>
<heading>Reminder    </heading>
<body>Don't forget me this weekend!</body>
</note>

I again modified my code like this.

我再次像这样修改了我的代码。

//It will replace all the + and white spaces in the xml.
if(xml.indexOf("[+]")!=-1)){
xml = xml.replaceAll("[+ ]","").trim();
}

But, this code is giving me a result like the following.

但是,这段代码给了我一个如下结果。

<?xmlversion="1.0"encoding="ISO-8859-1"?>//here I lose the spaces. 
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

Here I am losing the spaces in the <?xmlversion="1.0"encoding="ISO-8859-1"?>.

在这里,我将丢失中的空格。

The other part of the xml body is OK.

xml正文的另一部分没问题。

    <note>
    <to>Tove</to>
    <from>Jani</from>
    <heading>Reminder</heading>
    <body>Don't forget me this weekend!</body>
    </note>

except this <?xmlversion="1.0"encoding="ISO-8859-1"?>.

除了。

When I am trying to run this in my application, I am getting SAXParcerException: Missing white spaces...etc.

当我试图在我的应用程序中运行它时,我得到SAXParcerException:缺少空格......等等。

How can I write my code exactly to get the file as,

如何准确编写我的代码以获取文件,

<?xml version="1.0" encoding="ISO-8859-1"?>
<note>
<to>Tove</to>
<from>Jani</from>
<heading>Reminder</heading>
<body>Don't forget me this weekend!</body>
</note>

My application is built on purely Jdk 1.4, web server as tomcat.

我的应用程序基于纯粹的Jdk 1.4,Web服务器构建为tomcat。

3 个解决方案

#1

Try with xlm.replaceAll("\\++", ""); to replace one or more + with nothing at once.

尝试使用xlm.replaceAll(“\\ ++”,“”);一次性取代一个或多个+。

#2

It seems you want to remove all "+" that appear before "</",:

您似乎想删除“

xml = xml.replaceAll("\\++<\", "<\");

This won't affect "+" appearing elsewhere, such as:

这不会影响其他地方出现的“+”,例如:

<tag>Bill + Ted+++</tag>

will become

<tag>Bill + Ted</tag>

#3

Maybe you can use

也许你可以使用

if (xml.contains("+")) {
    xml = xml.replace("+", "");
}

instead of

xml = xml.replaceAll("[+ ]","").trim();

with jdk 1.4 you can use

用jdk 1.4你可以使用

if (xml.indexOf("+") != -1) {
    xml = xml.replace("+", "");
}
