这是我的示例XML文件,实际上高于2gb。使用vtd-xml我已经实现了这么多:
当前代码:
https://gist.github.com/shadow-fox/21d1d4f30cbed0909f403c3ac0e1fa4d
public void reader() throws IOException, ParseException, NavException, XPathParseExceptionHuge, NavExceptionHuge,
XPathEvalExceptionHuge {
VTDGenHuge vg = new VTDGenHuge();
if (vg.parseFile("sku_extract_main.xml",true,VTDGenHuge.MEM_MAPPED)) {
VTDNavHuge vnh = vg.getNav();
AutoPilotHuge aph = new AutoPilotHuge(vnh);
aph.selectElementNS("*", "*");
int i = 0;
while (aph.iterate()) {
int t = vnh.getText();
if (t != -1) {
System.out.println(vnh.toString(vnh.getCurrentIndex()) + "|||" + vnh.toNormalizedString(t));
i++;
}
}
}
}
当前结果:
PVAL|||298374234
PVAL|||1231
PVAL|||brown
PVAL|||medium
PVAL|||7
PVAL|||solid
PVAL|||brown
我想要的是什么:
Sku_ID|||298374234
LotNum|||1231
COLOR|||brown
WIDTH|||medium
SIZE|||7
Pattern|||solid
Color Family|||brown
示例xml:
<?xml version="1.0" encoding="UTF-8" ?>
<RECORDS>
<RECORD>
<PROP NAME="Sku_ID">
<PVAL>298374234</PVAL>
</PROP>
<PROP NAME="LotNum">
<PVAL>1231</PVAL>
</PROP>
<PROP NAME="COLOR">
<PVAL>brown</PVAL>
</PROP>
<PROP NAME="WIDTH">
<PVAL>medium</PVAL>
</PROP>
<PROP NAME="SIZE">
<PVAL>7</PVAL>
</PROP>
<PROP NAME="Pattern">

<PROP NAME="Color Family">

</PROP>
</RECORD>
</RECORDS>
我不想硬编码attr
名称。我想在他们访问它们时检索它们。我该怎么做?
答案 0 :(得分:1)
下面是我编写代码以编辑attr名称和值...它是基于xpath的...
