如何实现用首字母搜索新闻标题

Answer 1

采用xpath
例子
<script type="text/javascript">
xml = "<root><title>aaaa</title><title>bbb</title><title>acccc</title></root>"
doc = new ActiveXObject("MSXML2.DOMDocument")
doc.async = false;
doc.loadXML(xml);
doc.setProperty("SelectionLanguage", "XPath")
nlist = doc.selectNodes("/root/title[contains(.,'a')]");
for(i=0;i<nlist.length;i++)
{
 alert(nlist.item(i).text);
}
</script>
