在没有父节点的情况下解析XML文档-JAVA

Question

I have an XML file that needs to be parsed to output the data of an element. However, the file doesn't have a parent node and the conventional way to parse XML files is giving me this error:

The markup in the document following the root element must be well-formed.

XML File:

<row>
    <dam>bellair dam</dam>
    <last_year>70.6</last_year>
    <fsc>4.3</fsc>
    <latitude>33:42:43</latitude>
    <river>brak river</river>
    <last_week>35.9</last_week>
    <this_week>35.9</this_week>
    <longitude>20:35:52</longitude>
</row>
<row>
    <dam>berg river dam</dam>
    <last_year>52.7</last_year>
    <fsc>127.1</fsc>
    <latitude>33:54:25</latitude>
    <river>berg river</river>
    <last_week>37.3</last_week>
    <this_week>38.2</this_week>
    <longitude>19:3:30</longitude>
</row>
<row>
    <dam>brandvlei dam</dam>
    <last_year>38.0</last_year>
    <fsc>286.1</fsc>
    <latitude>33:42:42.88</latitude>
    <river>lower brandvlei river</river>
    <last_week>20.7</last_week>
    <this_week>20.5</this_week>
    <longitude>19:25:7.85</longitude>
</row>

Is there a way to parse the data in the XML file as string and use string manipulation to work on it? Because the conventional way of parsing the file is not working. Plus I cannot change (add) a root node to the XML file. Or how about writing the data to a text file?

Example of output:

Enter name of the data file:
testdata.xml
The dams are:
bellair dam
berg river dam
brandvlei dam

Answer 1

Because you have a malformed XML you will have a few options. You can either modify the input, write your own parser or partially parse each row as an xml.

A suggestion:

File file = new File("malformedXmlMissingRoot.xml");
FileInputStream fis = new FileInputStream(file);
List<InputStream> streams = Arrays.asList(
    new ByteArrayInputStream("<root>".getBytes()),
    fis,
    new ByteArrayInputStream("</root>".getBytes()));
InputStream cntr = new SequenceInputStream(Collections.enumeration(str));

and use that InputStream in your typical XML parser.
